Chapter 1 General Description
This chapter briefly introduces the features, design concept and operation mode of the HIPULSE U UPS.
1.1 Features
The HIPULSE U UPS is connected between a critical load, such as a computer, and its 3-phase mains power supply.
Being designed to furnish a well regulated 3-phase output power supply under all rated load and input supply
conditions, the system offers the user the following advantages:
z increased power quality
The UPS has its own internal voltage and frequency regulators which ensure that its output is maintained
within close tolerances independent of voltage and frequency variations on the mains power lines.
z increased noise rejection
By rectifying the input AC power to DC power, and then converting it back to AC power, any electrical noise
present on the input mains supply line is effectively isolated from the UPS output, therefore the critical load
sees only clean power.
z power blackout protection
If the mains power fails, the UPS continues to power the critical load from its battery source, leaving the load
immune from power disturbances.
1.2 Design Concept
1.2.1 HIPULSE U Module Design
This section describes the operating principle of an individual module. The UPS basically operates as an AC-DC-AC
converter (see Figure 1-1). The first conversion stage (from AC to DC) uses a 3-phase, fully controlled
silicon-controlled resistor (SCR) bridge rectifier to convert the incoming mains supply into a regulated DC busbar.

Single module block diagram
The DC busbar produced by the rectifier provides both battery charging power – being equipped with a temperature
compensated battery charging system, to prolong battery life – and power to the inverter section – which utilizes the
latest integrated gate bipolar transistor (IGBT) switching space vector pulse width modulation (SVPWM) design – and
provides the second conversion phase, that is, reconverting the DC busbar voltage back into an AC voltage
waveform.
During normal operation, both the rectifier and inverter sections are active and provide regulated load power whilst
simultaneously charging the battery. In the event of a mains power failure, the rectifier becomes inoperative and the
inverter is powered solely from the battery. Critical load power is maintained under these conditions until the battery is
fully discharged, whereupon the UPS shuts down. The end of battery discharge is assumed when the battery voltage
falls below a preset value (that is, 330Vdc for a 400Vac system).
The period for which the load can be maintained following a mains power failure is known as the system’s “Autonomy
Time” and is dependent upon both the battery A/Hr capacity and the applied percentage load.

Chapter 1 General Description
1.2.2 Bypass Supplies
The circuit block annotated “Static switch” in Figure 1-2 contains an electronically controlled switching circuit, which
enables the critical load to be connected either to the inverter output or to a bypass power source through the static
bypass line. During normal system operation, the load is connected to the inverter, and the inverter-side of the static
switch is closed. But in the event of a UPS overload or inverter failure, it is automatically transferred to the static
bypass line.

Figure 1-2 UPS power switches configuration
To provide a clean (no-break) load transfer between the inverter output and static bypass line, the static switch
activates connecting the load to the bypass supplies. To achieve this, the inverter output and bypass supply must be
fully synchronized during normal operating conditions. This is achieved through the inverter control electronics, which
make the inverter frequency track that of the static bypass supply provided that the bypass remains within an
acceptable frequency window.
A manually controlled, maintenance bypass supply is also incorporated into the UPS design. Its purpose is to enable
the critical load to be powered from the mains (bypass) supply while the UPS is shut down for routine maintenance.
Note: The load equipment is not protected from normal supply aberrations when operating on bypass side or in the
maintenance bypass mode.
1.2.3 System Control Philosophy
Normal operation
During normal operation, that is, when the UPS input supply is present and within specification, both the rectifier and
inverter sections are active and the static switch is turned on to connect the inverter output to the critical load busbars.
The battery circuit breaker (BCB) is also closed and the battery is therefore permanently float charged at the DC
busbar voltage level.
(“1+N” parallel UPS system) Note: As the unit outputs are connected in parallel, the system checks that the inverter
control circuits are perfectly synchronized with one another and with the bypass mains in terms of both frequency and
phase and that they have the same output voltages. Current supplied to the load is automatically divided among
UPSs. A warning message appears while synchronization is in progress.
A module's static switch cannot close until these conditions are satisfied.
Mains failure
If the power mains has a failure or is out of tolerance the rectifier will go off automatically, while the inverter will
continue to operate on power from the battery for a period of time which depends on the load and the capacity of the
battery. If the mains supply has not returned within this time, the inverter will go off automatically and an alarm
message will appear on the operator control and display panel of the UPS.
Critical load will not be interrupted in the event of a drop or return of the AC power mains.

Chapter 1 General Description

Return of power mains
When the mains returns within the required tolerance, the rectifier will start up again automatically and gradually
(power walk-in), supplying power to the inverter and recharging the battery at the same time. There will be no
interruption of the critical load.
Off-battery
If the battery system only is taken out of service for maintenance, it is disconnected from the rectifier/charger and
inverters by means of (an) external disconnect breaker(s). The UPS shall continue to function and meet all of the
specified steady-state performance criteria, except for the power outage back-up time capability.
UPS module fault
In the event of an inverter fault, the static transfer switch will automatically transfer the load onto the bypass mains
with no interruption. In such an event, seek technical assistance from Emerson local customer service center.
(“1+N” parallel UPS system) In the event of a fault in a unit, the unit’s static transfer switch will automatically
exclude the unit from the system. If the system is still capable of providing the required load, the remaining units will
continue to supply the load with no interruption. When the units still present in the system are no longer capable of
fulfilling power requirements, the load will automatically be transferred onto the bypass mains.
Overload
In the event of an overload at the inverter output which lasts longer than the typical time/current (refer to table 8-6),
the inverter will shut down and the static transfer switch will automatically transfer the load onto the bypass mains
with no interruption. If the overload falls within the typical time/current that has been specified, the load will be
returned to the inverters when the power drops to a level which can be supported by the number of active units in the
system (parallel “1+N”).
In the event of a short circuit in the output, the load will normally be transferred onto the bypass mains, which will
cause the inverter to shut down. This switch is determined above all by the features of the protective devices in use in
the system.
In either case, an alarm message will appear on the operator control and display panel of the UPS.
(“1+N” parallel UPS system) The control logic system constantly monitors load requirements and controls the power
supplied by the UPS modules. In the event that an overload condition is sustained for greater than a preset time, the
load will transfer to the bypass mains supply, when the number of active modules is unable to satisfy load
requirements. The load returns to the inverter supply if the power is reduced to a value that can be sustained by the
number of active modules in the system.
Maintenance bypass
A second bypass circuit contained in the UPS cabinet, identified as the maintenance bypass line, is included to
enable a raw mains supply to be made available to the load while facilitating a safe working environment for carrying
out scheduled UPS system maintenance or trouble shooting. The circuit is manually selected by the maintenance
bypass switch in the OFF position.
Warning
The internal maintenance bypass must not be used when the UPS system is comprised of more than two UPS modules in
parallel.
CAUTION: If an automatic circuit breaking device is not present in the input distribution panel, there remains a dangerously high
voltage at the output busbars and also on the input busbars of the UPS module that is switched off.
1.2.4 ECO Mode (For Single UPS Only)
In ECO mode, the system prefers to put the load on the bypass mains, with the inverter on stand-by. The load is
switched over to the inverter when the mains goes outside of standard frequency and voltage values (settable).
The ECO mode configuration requires a different setup in the default menu configuration.

Chapter 1 General Description
Operating procedures in ECO mode are the same as those described in Chapter 5 Operating Instructions, except
that the load is normally on the bypass mains, the Inverter LED is normally off, and the corresponding alarm message
Bypass mode will appear on the LCD.
Warning
In ECO mode the load is not protected against mains distortion.
1.2.5 UPS Power Switch Configuration
Figure 1-2 illustrates the HIPULSE U UPS module in what is known as the split bypass configuration. In the split
bypass configuration, the static bypass line is connected by a separate power switch to a dedicated bypass power
source which also feeds the maintenance bypass line. Where a separate power source is not available the bypass
(Q2) and rectifier (Q1) input supply connections would be linked together.
With the exception of the maintenance bypass switch, all the switches shown must be closed during normal UPS
operation.
1.2.6 Battery Circuit Breaker
The battery should be connected to the DC busbar through a circuit breaker fitted inside the battery cabinet — or
located adjacent to the batteries where a battery cabinet is not used. This circuit breaker is closed manually, but it
contains an undervoltage release coil which enables it to be tripped from the UPS control electronics following certain
detected faults. It also has a magnetic trip facility for overload protection.
1.2.7 Battery Temperature Compensation
HIPULSE U UPS system offers a battery temperature compensation circuit. As the temperature inside the battery
cabinet/area rises, the DC busbar voltage reduces in order to sustain the battery at its optimum charge voltage. This
must be used in conjunction with the battery temperature sensing device.
1.2.8 System Expansion
If necessary, a single module system can be expanded to cater for an increased load requirement by adding
additional modules — up to a maximum of six UPS modules can be connected in parallel.
System expansion requires a change in the SETUP of the operator control and display panel of each UPS module.
Note:
1. System expansion should be carried out only by trained service personal.
2. The individual modules connected to the system must be of the same power rating.
1.3 Operation Mode
The UPS permits operation in the following alternative modes:
Normal mode
The UPS inverter continuously supplies the critical AC load. The rectifier/charger derives power from the AC mains
input source and supplies DC power to the inverter while simultaneously float or boost charging its associated backup
battery.
Battery mode
Upon failure of the AC mains input power, the critical AC load is supplied by the inverter, which obtains power from
the battery. There is no interruption in power to the critical load upon failure or restoration of the AC mains input
power after which the Normal mode operation will continue without the necessity of user intervention.
Note: Battery start device (optional) is available for switching the UPS on into Battery (charged) mode directly during
mains failure.

Chapter 1 General Description

Auto-restart mode
The battery becomes exhausted following an extended AC mains failure. The inverter shuts down when the battery
reaches the end-of-discharge voltage (EOD). The UPS can be programmed to Auto Recovery after EOD after a set
variable delay time. This mode and any delay time are programmed by the commissioning engineer.
Bypass mode
The load power is supplied though the mains static bypass line. This may be considered as an intermediate operating
condition being utilized for the purpose of load transfers between inverter and maintenance bypass or supply under
abnormal operating conditions.
Maintenance mode
The UPS is shut down but the load is connected to the unprotected mains through the maintenance bypass supply
line.
Source Share mode
The UPS has the capability of fully supporting their critical load while limiting the amount of power taken from the
incoming AC mains supply. Any balance of power required is supplied by the UPS battery. This feature is useful, for
example, in applications where peak-hour tariffs apply or where a generator smaller than needed feeds the UPS
during mains outages. The Source Share mode is user-activated and the ratio of the mains AC input power is
programmable from 20% to 100% of the rated UPS power.
ECO mode (for single UPS only)
All power switches and the BCB are closed, the system prefers to put the load on the bypass mains, with the inverter
on stand-by; only when the voltage and/or frequency of the bypass supply are beyond pre-defined and adjustable
limits is the critical AC load transferred to the inverter.
Parallel redundancy mode (system expansion)
For higher capacity or higher reliability or both, the outputs of up to six UPS modules can be programmed for directly
paralleling while a built-in parallel controller in each UPS ensures automatic load sharing.
Frequency converter mode
The UPS can be programmed into Frequency Converter mode for either 50Hz or 60Hz stable output frequency. The
input frequency may vary from 45Hz to 65Hz. In this mode, it is required to open the bypass switch to disable the
static bypass operation, and the battery becomes optional depending on any requirement to operate in Battery mode.

The UPS equipment should be installed by a qualified engineer in accordance with the information contained in this chapter and
all equipment not referred to this manual is shipped with details of its own mechanical and electrical installation.
Warning: battery hazards
Special care should be taken when working with the batteries associated with this equipment. When connected together, the
battery terminal voltage will exceed 400Vdc and is potentially lethal.
1. Eye protection should be worn to prevent injury from accidental electrical arcs.
2. Remove rings , watches and all metal objects.
3. Only use tools with insulated handles.
4. Wear rubber gloves.
5. If a battery leaks electrolyte, or is otherwise physically damaged, it must be replaced, stored in a container resistant to sulfuric
acid and disposed of in accordance with local regulations.
6. If electrolyte comes into contact with the skin the affected area should be washed immediately with water.
Warning
The UPS system can be connected to an isolated neutral (IT) power system.
This chapter describes the environmental requirements and mechanical considerations that must be taken into
account when planning the positioning and cabling of the UPS equipment.
Because every site has its peculiarities, it is not the aim of this chapter to provide step-by-step installation instructions,
but to act as a guide as to the general procedures and practices that should be observed by the installing engineer.
2.2 Environmental Considerations
2.2.1 UPS Location
The UPS module should be located in a cool, dry, clean-air environment with adequate ventilation to keep the
ambient temperature within the specified operating range (see Table 8-2).
All models in the HIPULSE U UPS range are cooled with the aid of internal fans. Cooling air enters the module
through ventilation grills located at various parts of the cabinet and exhausted through grills located in the cabinet roof.
When the cabinet is located on a raised floor, and bottom cable entry is used, additional cooling air also enters the
UPS through the floor void. If necessary, a system of extractor fans should be installed to aid cooling-air flow, and a
suitable air filtration system used where the UPS is to operate in a dirty environment.
Note:
1. When batteries are cabinet-mounted adjacent to the UPS module, it is the battery which dictates the designed
maximum ambient temperature, not the UPS.
2. Power losses from the system which may be used in an air conditioning system are intended for operation using
the inverter, as in the ECO mode configuration they would be undersized.

2.2.2 Battery Location
Temperature is a major factor in determining the battery life and capacity. Battery manufacturers quote figures for an
operating temperature of 20°C. Operating above this temperature will reduce the battery life, and operation below this
temperature will reduce the battery capacity. On a normal installation the battery temperature is maintained between
15°C and 25°C. Batteries should be mounted in an environment where the temperature is consistent and even over
the whole battery. Keep batteries away from main heat sources or main air inlets, and so on.
The batteries can be mounted in a purpose-built battery cabinet, which is positioned adjacent to the UPS module.
Pedestals are required for the battery cabinets when they are located on raised floors, in the same way as for the
UPS cabinets If the batteries are rack-mounted, or otherwise located remote to the main UPS cabinet, a BCB must
be mounted as close as possible to the batteries themselves, and connected using the most direct route possible.
2.3 Mechanical Considerations
2.3.1 System Composition
A UPS system can comprise a number of equipment cabinets, depending on the individual system design
requirements, for example, UPS cabinet, battery cabinet. The 300kVA UPS (12-pulse rectifier) and 400kVA UPS
comprise a main cabinet and a side cabinet. In general, all the cabinets used in a particular installation are of the
same height and designed to be positioned side-by-side to form an aesthetically appealing equipment suit.
2.3.2 Moving The Cabinets
Warning
Ensure that any lifting equipment that used in moving the UPS cabinet has sufficient lifting capacity.
Ensure that the UPS weight is within the designated surface weight loading of any handling equipment. See Table 8-3
for UPS weight details.
The UPS cabinet can be moved by fork lift. Before moving the UPS cabinet, it is necessary to remove both the front,
rear (or side) grille panels located at the base of the cabinet.
In the eventuality that the equipment cannot be moved by fork lift, then rollers should be used.
2.3.3 Clearances
As HIPULSE U UPS has no ventilation grills at either the sides or the rear, no clearances are required. However,
where space permits, a clearance of approximately 600mm at the back will ease access to magnetic component parts.
Clearance around the front of the equipment should be sufficient to enable free passage of personnel with the doors
fully opened.
2.3.4 Fixing Of The Magnetic Components
Before the equipment is in place, remove the transportation restraints that hold the output transformer in place. For
procedures, refer to Appendix 1 Transportation Restraints Removing Procedures.
2.3.5 Cable Entry
Cables can enter for HIPULSE U UPS and battery cabinet either from below or through either side.
Side entry is made possible by removing blanking pieces fitted in the side panel to reveal the cable entry holes.
This cable entry method allows the equipment to be positioned on a solid floor without the need for cable trenching
and allows cables to pass from one module to the other when positioned side-by-side.
Optionally a top cable entry extension may be used.
Note: When selecting the power cables for side entry to a module located on a solid floor, consideration must be
given to the minimum permissible radius of the proposed cables to ensure that they can be fashioned to reach the
UPS connection busbars.

2.4 Preliminary Checks
Before you install the UPS hardware you should carry out the following preliminary checks:
1. Verify that the UPS room satisfies the environmental conditions stipulated in the equipment specification, paying
particular attention to the ambient temperature, air exchange system, and dust density.
2. Remove any packaging debris, visually examine the UPS and battery equipment for transit damage, both internally
and externally. Report any such damage to the shipper immediately.

Chapter 3 Electrical Installation
This chapter introduces the electrical installation of the HIPULSE U UPS, including the procedures or methods for
power cabling and control cabling, and the distance from floor to connection point.
The UPS requires both power cabling and control cabling once it has been mechanically installed. All control cables,
whether screened or not, should be run separate from the power cables in metal conduits or metal ducts which are
electrically bonded to the metalwork of the cabinets to which they are connected.
3.1 Power Cabling
Warning
BEFORE CABLING UP THE UPS, ENSURE THAT YOU ARE AWARE OF THE LOCATION AND OPERATION OF THE
EXTERNAL ISOLATORS THAT CONNECT THE UPS INPUT/BYPASS SUPPLY TO THE MAINS DISTRIBUTION PANEL.
CHECK THAT THESE SUPPLIES ARE ELECTRICALLY ISOLATED, AND POST ANY NECESSARY Warning SIGNS TO
PREVENT THEIR INADVERTENT OPERATION.
For cable entry, refer to 2.3.5 Cable Entry.
3.1.1 System Configuration
The power cables of the system must be size with respect to the following description:
Module input cables
The input cables must be sized for the maximum input current, including the maximum battery recharge current,
given in the Table 3-1, with respect to the module rating and the input AC voltage.
Module bypass and output cables
The bypass and output cables must be sized for the nominal output current, given in the Table 3-1, with respect to the
module rating and the output AC voltage.
Battery cables
Each UPS module has its own battery which is connected using two cables, one positive and one negative. The
battery cables must be sized for the battery discharge current at the end-of-discharge voltage, as given in Table 3-1
with respect to the module rating.
3.1.2 Cable Rating
The power cables can be sized to suit the UPS module rating according to Table 3-1.

Chapter 3 Electrical Installation
3.1.3 General Notes
The following are guidelines only and superseded by local regulations and codes of practice where applicable:
1. The neutral conductor should be sized for 1.5 times the output/bypass phase current.
2. The earth conductor should be sized at 2 times the output/bypass conductor (this is dependent on the fault rating,
cable lengths, type of protection etc.).
3. Consideration should be given to the use of paralleled smaller cables for heavy currents, as this can ease
installation considerably.
4. When sizing battery cables, a maximum volt drop of 3Vdc is permissible at the current ratings given in Table 3-1.
5. In most installations, especially those concerning parallel multi-module systems, the load equipment is connected
to a distribution network of individually protected busbars fed by the UPS output rather than being connected directly
to the UPS itself. Where this is the case the UPS output cables can be rated to suit the individual distribution network
demands rather than being fully load-rated.
3.1.4 Cable Connections
The rectifier input, bypass, output and battery power cables (all require lug type terminations) are connected to
busbars situated below the power isolator switches, as shown in Figure 3-2 and Figure 3-3.
A terminal block X3 is used for connecting the control cables to the battery circuit breaker (BCB). These are female
spade type connections (fast-on 6.3*0.8) and are described later in 3.3.2 Battery Control.
3.1.5 Safety Earth
The safety earth busbar is located near the input and output power supply connections as shown in Figure 3-2 and
Figure 3-3. The safety earth cable must be connected to the earth busbar and bonded to each cabinet in the system.
All cabinets and cable trunking should be earthed in accordance with local regulations. The earth cable should be
bound with binding strips onto the metallic column for cabling so as to prevent the fixing screw of the earth cable from
loosening in the case the earth cable is pulled.
Warning
FAILURE TO FOLLOW ADEQUATE EARTHING PROCEDURES CAN RESULT IN ELECTRIC SHOCK HAZARD TO
PERSONNEL, OR THE RISK OF FIRE, SHOULD AN EARTH FAULT OCCUR.
3.1.6 Protective Devices
For safety reasons, it is necessary to install, external to the UPS system, circuit breaking protective devices in the
input AC supply and towards the battery. Given that every installation has its own characteristics, this chapter
provides general useful information for qualified installation engineers, with knowledge of operating practices, of
regulatory standards, and of the equipment to be installed.
Rectifier and bypass input supply of the UPS
1. Protection against excessive overcurrents and short circuits in the mains supply input
These inputs must be protected, installing suitable protective devices at the distribution panel of the incoming mains
supply, considering that the protection should discriminate with overload capacity of the system (see Table 8-6 and
Table 8-7).
2. Split bypass
In the case of a split bypass being used, separate protective devices should be installed in the incoming mains
distribution panel. The protective devices must be selected for the nominal input current, with respect to the UPS
rating and the input AC supply voltage as given in Table 3-1.
3. Protection against earth faults
In the event of a residual current detector (RCD) device being installed upstream of the input supply, one must take
into account the transient and steady state earth leakage currents that are produced during start-up of the UPS.
HIPULSE U UPS Single Module And “1+N” (Expandable) 160/200/300/400kVA User Manual
Chapter 3
Electrical Installation
17
The presence of a radio frequency interference (RFI) suppression filter inside the UPS determines a residual earth
current greater than 3.5mA and less than 1000mA.
Residual current circuit breakers (RCCBs) must be sensitive to DC unidirectional pulse (Class A) in the network and
insensitive to transient current pulses. They are identified by the symbols respectively:
Figure 3-1
Symbols of residual current circuit breaker (RCCB)
These isolators must have an average sensitivity, possible adjustable between 0.3A and 1A.
It is recommended that the selectivity with every RCD be verified both upstream of the input distribution board and
downstream (towards the load).
UPS battery
The UPS Battery is protected by means of a control circuit that operates the tripping mechanism of an automatic
circuit breaking device (having a variable trip setting). The tripping mechanism using an undervoltage release coil that
operates on a present minimum voltage level.
The circuit breaker is essential for maintenance of the battery and is normally located near to the battery installation.
Output of the system
In the eventuality that an external distribution panel is used for load distribution, the selection of protective device
must provide discrimination with those that are use at the input to the UPS module.
3.1.7 Cabling Procedure
Once the equipment has been finally positioned and secured, refer to Figure 3-2 and Figure 3-3 to connect the power
cables as described in the following procedures:
1. Verify that the UPS equipment is totally isolated from its external power source and all the UPS power isolators are
open. Check that these supplies are electrically isolated, and post any necessary warning signs to prevent their
inadvertent operation.
2. Open the UPS door and remove the lower protective cover to gain access to the connections bars.
3. Connect the safety earth and any necessary bonding earth cables to the copper earth busbar located on the floor
of the equipment below the power connections.
Note: The earthing and neutral bonding arrangement must be in accordance with local and national codes practice.
Common Input Connections
4. For common bypass and rectifier inputs, connect the AC input supply cables between the mains distribution panel
and the UPS input supply busbars (U1-V1-W1-N1 terminals) and tighten the connections to 13 Nm (M8 bolt), and to
26 Nm (M10 bolts). ENSURE CORRECT PHASE ROTATION.
Split Bypass Connections
5. If a split bypass configuration is used, connect the AC input supply cables to the input busbars (U1-V1-W1
terminals) and the bypass AC supply cables to the bypass busbars (U2-V2-W2-N2 terminals) and tighten the
connections to 13 Nm (M8 bolt), to 26 Nm (M10 bolt), and to 50 Nm (M12 bolt). ENSURE CORRECT PHASE
ROTATION.
Warning
Ensure that any links (*) fitted between rectifier input and bypass busbars are removed. But do not remove those between the
neutral terminals. See Figure 3-2 and Figure 3-3.
Output System Connections

Chapter 3 Electrical Installation
6. Connect the system output cables between the output busbars (N3-U3-V3-W3 terminals) and the critical load and
tighten the connections to 13 Nm (M8 bolt), to 26 Nm (M10 bolt), and to 50 Nm (M12 bolt). ENSURE CORRECT
PHASE ROTATION.
Warning
If the load equipment will not be ready to accept power on the arrival of the commissioning engineer then ensure that the system
output cables are safely isolated at their ends.
UPS Battery Connections
7. Connect the battery cables between the UPS terminals (+/-) and its associated BCB. Connect screened auxiliary
cables from each BCB control board to the auxiliary terminal block (X3). OBSERVE THE BATTERY CABLE
POLARITY.
Warning
Do not close the BCB before the equipment has been commissioned.
8. Refit the lower protective cover.
Note: For split bypass operation,
ensure that the busbars ( *)
between the bypass input and
rectifier input are removed.

4.1.6 EPO Button
As shown in Figure 4-3, the UPS door provides an emergency power off (EPO) button. It is housed beneath a safety
cover to prevent inadvertent operation. After the EPO button has been pressed and hold for 2 seconds, it disables the
static switch block entirely (so removing load power). It also disables the rectifier and inverter, and trips the battery
circuit breaker. Under normal circumstances it does not remove UPS input power since this is applied through a
manually controlled external isolator; however, if the UPS input supply is connected through circuit breaker having an
electrical trip facility, the EPO switch can be used to drive the external circuit breaker’s trip circuit so as to remove the
UPS input power.

This alarm is triggered by an inverter software routine when the amplitude or frequency of bypass
voltage is beyond the normal range. The amplitude threshold is fixed for positive and negative 10%
rating.
This alarm automatically resets once the bypass voltage goes normal. 1. First verify that the bypass
voltage and frequency displayed on the operator control and display panel is within the selected
range. Note here the rated voltage and frequency are specified by the system voltage level and
output frequency level respectively. 2. If the displayed voltage is believed to be abnormal, then verify
the bypass voltage and frequency presented to the UPS. Check the external supply if it is found to
be faulty
This alarm is triggered by an inverter software routine when the amplitude or frequency of bypass
voltage exceeds the limit. This alarm automatically resets once the bypass voltage goes normal.
First check if there are some relevant alarms such as Bypass disconnect open, Bypass phase
reverse. If they appear, solve them first. 1. Then verify that the bypass voltage and frequency
displayed on the operator control and display panel is within the bypass limit. Note here the rated
voltage and frequency are specified by the system voltage level and output frequency level
respectively. 2. If the displayed voltage is believed to be abnormal, then verify the bypass voltage
and frequency presented to the UPS. Check the external bypass supply if it is found to be faulty. If
the utility is likely to trigger this alarm frequently, the bypass limit can be changed a little larger
through the configuration software according to the customer’s agreement
This alarm is triggered by an inverter software routine when the inverter and bypass waveforms are
misaligned by more than 6 degrees in phase. This alarm resets automatically once the condition is
no longer true. 1. First check if the alarm Bypass unable to trace or Bypass abnormal occurs. If so,
solve it first.
2. Verify the waveform of the bypass voltage. If it is too distorted, ask the customer to verify and seek
any possible measurements

The UPS is confirmed to be overload when the load arises above 105% nominal rating. The alarm
automatically resets once the overload condition is removed. 1. Confirm that the alarm is true by
checking the load percent indicated on the LCD to determine which phase is being overloaded. 2. If
the alarm is true, measure the actual output current to verify that the indications are valid.
Disconnect unnecessary load and ensure the safety. In a parallel system, a severe load sharing error
can also leads to the alarm
The UPS parallel system is confirmed to overload when the total load arises above 105% nominal
rating for the set basic number of UPSs. The alarm automatically resets once the overload condition
is removed.
1. Confirm that the alarm is true by checking the system load percent indicated on the LCD to
determine which phase is being overloaded. 2. If the alarm is true, measure the actual output current
to verify that the indications are valid.
Disconnect unnecessary load and ensure the safety. In a parallel system, a severe load sharing error
can also leads to the alarm
The UPS is confirmed to overload and the overload times out.
Note 1: the highest loaded phase will indicate overload timing-out first. Note 2: When the timer is
active then alarm “unit overload” should also be active as the load is above nominal.
Note 3: When the timer has expired, the inverter Static Switch is opened and the load transferred to
bypass. The inverter shutdown and will restart after 10 seconds. Note 4: If the load decreases lower
than 95% after 5 minutes, the system will transfer back to inverter mode.
Confirm that the alarm is genuine by checking the load percent indicated on the LCD. If an overload
is indicated then check the load, and investigate any additional load connected prior to the alarm (if
applicable)
Both bypass and inverter voltages unavailable. Load interruption

Chapter 5 Operating Instructions
This chapter provides detailed operating notes and instructions of the HIPULSE U UPS.
5.1 Introduction
5.1.1 Notes
Important
Only after an authorized engineer has conducted the initial power-on and finished the UPS configuration is the user allowed to
operate the UPS.
No user accessable parts are located behind covers that require a tool for their removal. Only qualified service personnel are
authorised to remove such covers.
Hazardous voltages are always present at the UPS input and output terminals. If the UPS is fitted with an internal Class A filter,
the filter carries hazardous voltages too.
1. All the user controls and indicators (LED) mentioned in these procedures are identified in Chapter 4 Operator
Control And Display Panel.
2. The audible alarm may annunciate at various points in these procedures. It can be canceled at any time by
pressing the SILENCE ON/OFF button.
3. The HIPULSE U UPS system incorporates an optional automatic boost charge facility, which can be used in
systems containing conventional flooded lead-acid batteries. If this type of battery is used in your installation you may
notice that the battery charger voltage may be greater than its nominal (432Vdc for 380Vac, 446Vdc for 400Vac and
459Vdc for a 415Vac system) when the mains supply returns from a prolonged outage. This is the normal response of
the boost charge facility: the charger voltage should return to normal after a few hours.
5.1.2 Power Switches
The UPS can be separated by means of power switches, mounted inside the cabinet and accessible after opening
the front door, which has a key. The location of the UPS power switches is shown in Figure 5-1 and Figure 5-2.
The UPS module power switches are:
Q1 — input switch: Connects the UPS with the mains supply.
Q2 — bypass switch: Connects the UPS with the bypass supply.
Q3 — maintenance bypass switch (padlocked): Permits supply of the load directly by the bypass line for maintenance
of the UPS module.
The internal maintenance bypass must not be used when the UPS system is comprised of more than two UPS
modules in parallel.
Q5 — output switch: Connects the output of the UPS to the load.
Note: The battery circuit breaker (BCB) is not expected inside of the UPS and should be installed in the proximity of
the respective battery.

5.2 Start-Up Procedure (Into Normal Mode)
This procedure must be followed when turning on the UPS from a fully powered down condition, that is, where the
load is not being initially supplied at all or where supplied by the maintenance bypass switch. It is assumed that the
installation is complete, the system has been commissioned by authorized personnel and the external power isolators
are closed.
Warning – Mains voltage will be applied to UPS output terminals
This procedure results in mains voltage being applied to the UPS output terminals.
Isolate and attach warning labels to any downstream load connections, as applicable.
1. Open the UPS door to gain access to the power switches.
2. Close the bypass switch Q2 and output switch Q5. Close also any external output isolation switches, where used.
The LCD display becomes active and after initialization, the UPS output is powered from the bypass. At this point, the
status of the LEDs is as described in Table 5-1.

3. Close the input switch Q1.
The rectifier LED flashes during the startup of rectifier and becomes steady green once the rectifier reaches normal
operation state after about 15s.
4. Verify the bus voltage and the battery polarities, and close the BCB, which is located in the BCB box.
5. Following battery availability being detected by the UPS, the red battery LED extinguishes.
6. Open (or confirm open) the internal maintenance bypass switch Q3.
7. Press and hold the INVERTER ON button for two seconds.
The inverter will start up and the inverter LED flashes while it synchronizes to the bypass voltage frequency.
After the inverter is ready, the UPS transfers from bypass to inverter, the bypass LED turns off, and the inverter LED
becomes steady green.
8. Check that no “Warning” message is displayed in the top right corner of the LCD screen and the status of the LEDs
is as described in Table 5-2.

5.4 Battery Test Mode Procedures
The Battery test mode procedures transfer the UPS into shared source mode wherein approximately 15% of the load
power is supplied by the battery and the balance by the AC input mains.
Battery test type and preconditions
1. There are two battery tests to select from:
z Battery maintenance test: verifies the battery integrity and leads to the battery being partly discharged (20%).
z Battery capacity test: verifies precisely the battery capacity and leads to the battery being fully discharged (until
Battery low prewarning alarm)
2. The tests can be carried out from the operator control and display panel of the UPS by the operator when the
following conditions are satisfied:
z The load must be between 20% and 80% of rated UPS capacity.
z The battery must have been float charging for 5 hours or more.
The battery test procedures are password controlled and menu driven. The test is immediately terminated in the
event of a battery or a mains failure and the total load power is supported from the remaining source without
interruptions.
Test procedure
1. Select the Command menu on the LCD screen on the operator control and display panel of the UPS.
Use the right or left arrow key to navigate to the Command menu.
2. Select the desired test (the Battery maintenance test or Battery capacity test option).

the AC input bypass supply though a maintenance bypass switch.
Caution – risk of load interruption
Except in emergency situations, so as not to risk a short interruption in powering the load, before initiating this bypass procedure,
confirm that no warning status is displayed in the top right corner of the LCD screen.
If a warning status is displayed, the operator will be prompted to confirm or cancel any action that can lead to load interruption.
1. Press the INVERTER OFF button on the operator control and display panel.
The UPS inverter will shut down and the load is supplied through the static bypass supply. At this point, the inverter
LED extinguishes, and the alarm LED turns on.
2. Close the maintenance bypass switch Q3.
The maintenance bypass supply is now in parallel with the UPS static switch supply, and the LCD shows messages
reflecting the actions taken (that is, maintenance bypass closed, etc.).
3. Open the output switch Q5.
This ends the bypass procedure. The load is now powered directly from the maintenance bypass supply.
Note
The load equipment is not protected from AC supply aberration.
Proceed with following steps if rectifier and battery shutdown is also required.
4. Press and hold the emergency power off (EPO) button on the UPS door for two seconds.
This will disable further rectifier, inverter, static switch and battery operation, but will not affect the maintenance
bypass switch.
Note
Before carrying out this step, verify that the EPO contact is not connected to any external switch or device.
5. Open the input switch Q1 and the bypass switch Q2.
6. Open the BCB, which is located in the BCB box.
All LED indications and messages on the operator control and display panel will extinguish as the mains driven
internal power supplies decay.
The load is now powered from the maintenance bypass supply and the UPS is completely shut down.
5.7 Shutdown Procedure (Complete UPS And Load Shutdown)
This procedure must be followed to completely power down the UPS and load. All power switches, isolators and
circuit breakers will be opened and power will be removed from the load.
Caution
The following procedure will switch off all power to the load equipment.

Chapter 5 Operating Instructions
1. Press the EPO button on the UPS door. This will disable rectifier, inverter, static switch and battery operation. The
Load will be de-energised.
Note: Except in an emergency situation, do not press any remote EPO button.
2. Open the UPS door to gain access to the power switches.
3. Open the input switch Q1.
4. Open the BCB, which is located in the BCB box.
5. Open the output switch Q5.
6. Open the bypass switch Q2.
7. Ensure that the maintenance bypass switch Q3 is open.
All LED indications and messages on the operator control and display panel will extinguish as the mains driven
internal power supplies decay.
8. To completely isolate the UPS from the AC supplies, the main external power input switches (both switches, where
split supplies are provided for rectifier and bypass) and external output switch must be opened and tagged with
warning labels accordingly.
5.8 EPO Procedure
The UPS provides an EPO button on the UPS door. The EPO button is designed to switch off the UPS in emergency
conditions (that is, fire, flood, etc.). To achieve this, just press and hold the EPO button for two seconds, and the
system will turn off the rectifier, inverter and stop powering the load immediately (including the inverter and bypass),
and the battery stops charging or discharging.
If the input utility is present, the UPS control circuit will remain active; however, the output will be turned off. To
remove all power from the UPS, the external feeder breaker should be opened.
5.9 UPS Reset Procedure
Once all appropriate measures have been taken to correct the problem indicated by the alarm message appearing on
the LCD, carry out this procedure to restore the UPS to regular operation following an EPO action or for the following
reasons: inverter overtemperature, cut-off overload, battery overvoltage, excessive switching, etc.
After confirming that the fault is cleared and there is no EPO signal:
1. Press the FAULT CLEAR button to clear all alarms.
Note
The rectifier restarts, and the bypass supplies power to the load. When the rectifier starts, the rectifier LED flashes. When the
rectifier is in normal operation (about 15s later), the rectifier LED turns steady green.
2. Press and hold the INVERTER ON button for two seconds.
Note
Five minutes after the overtemperature signal disappears, that is, when the overgemperature fault is eliminated, the rectifier will
automatically start.
After the EPO button is pressed, if the input utility is removed, the UPS will shut down completely. When input utility is
returned, if the bypass switch Q2 and output switch Q5 are closed, the UPS will start up on Bypass. There will be
power at the output terminals of the UPS.
Warning
If the maintenance bypass switch Q3 is closed and the mains input is available, the UPS has output.

Chapter 6 Battery
Chapter 6 Battery
This chapter introduces the battery, including the battery safety points, installation, maintenance, and the battery
protection function, as well as the connections of the optional battery circuit breaker (BCB) box and battery
temperature sensor.
6.1 Introduction
The UPS battery consists of battery blocks connected in series to provide a nominal DC input voltage for the UPS
inverter. The required autonomy time (the time that the battery can maintain supply to the load in the event of a mains
failure) is limited by the ampere-hour size of the individual battery blocks and in some cases this could mean several
strings are connected in parallel.
It must be possible to disconnect the battery from the UPS module when undertaking maintenance or service
procedures. This is facilitated by means of a suitably rated circuit breaker which must be located as close as possible
to the battery terminals, and the power and control cables connected to the UPS using the most direct route possible.
If multiple sets of batteries connected in parallel are used to increase battery autonomy, the extension must be fitted
with a sectioning device to permit work to be performed on one set of batteries while the others remain in service.
For external battery assembly, Emerson offers an optional battery circuit breaker (BCB) box, the features of which
depend on the size of the UPS. Normally, you must select a corresponding BCB box for each UPS, in order to
disconnect the battery from the UPS when the UPS requires maintenance or repair. The BCB box includes a BCB
control board. This box is designed to be either wall-mounted or assembled on a frame, and is connected between
the UPS and the battery. Refer to 6.9 BCB Box (Optional) for more information.
6.2 Safety
Special care should be taken when working with the batteries associated with the HIPULSE U UPS. When all the
cells are connected together, the battery terminal voltage will exceed 400V and is potentially lethal. A primary safety
consideration is to physically isolate the battery installation from all but appropriately qualified maintenance personnel;
which is best achieved by locating the cells in a key-lockable cabinet or a purpose-designed, dedicated battery room.
Warning
The following general battery safety precautions and warnings should be observed at all times:
1. A battery can present risk of electric shock or burn from high short circuit currents.
2. When connected in a string the voltage could be 460Vdc, this voltage is potentially lethal always observe high voltage
precautions.
3. Only qualified personnel should install or service batteries.
4. Eye protection should be work to prevent injury from accidental electrical arcs.
5. Remove rings, watches, necklaces, bracelets and all metal objects.
6. Only use tools with insulated handles.
7. Wear rubbers gloves and a rubber apron when handling batteries.
8. If a battery leaks electrolyte, or is otherwise physically damaged, it should be placed in a container resistant to sulphuric acid
and disposed of in accordance with local regulations.
9. If electrolyte comes into contact with the skin the affected area should be washed with plenty of clean water immediately.
10. Batteries must always be disposed of according to local environmental laws.
6.3 UPS Batteries
It is common practice in UPS installations to use valve-regulated cells. The term ‘valve regulated’ is used currently in
place of either ‘sealed’ or ‘maintenance free’ both of which have been used in the past.
Valve-regulated cells are not ‘sealed,’ and will vent, particularly on overcharge. The amount of gas given off is less
than for a flooded cell but when considering the design of the battery installation allowances must be made for
HIPULSE U UPS Single Module And “1+N” (Expandable) 160/200/300/400kVA User Manual
Chapter 6 Battery
47
adequate ventilation and heating of the cells. Boost charging must not be applied to valve regulated cells as this will
cause them to overcharge and subsequently vent.
Similarly, valve-regulated cells cannot be regarded as maintenance-free as they must be kept clean and their
connections checked periodically for tightness and lack of corrosion. Specific inspection instrument can also be used
to check each battery cell periodically to learn about the variation in capacity.
Batteries are fully charged before delivery; however, storage and transportation times mean that, inevitably, some
charge is lost by the time the battery is commissioned. All the cells forming the battery should be brought to the same
state of charge and be recharged within 6 months of the factory charge.
It is especially important that the battery is fully charged before attempting a witness test of the autonomy time. This
may require several days to complete; therefore any witness test concerning the batteries should take place only after
the battery has been on uninterrupted float charge for at least one week.
Cell performance typically improves after a few weeks in service or after two or three discharge and recharge cycles.
6.4 Installation Design Considerations
Note
Full safety instructions concerning the use and maintenance of UPS batteries are provided in the appropriate battery
manufacturers manuals. The battery safety information contained in this section relates to key considerations which must be taken
into account during the installation design process and might affect the design outcome depending on localized conditions.
6.5 Battery Installation And Maintenance
6.5.1 Temperature Considerations
Battery performance depends on the ambient battery temperature. Capacity and autonomy times are quoted for a
new battery operating at 20°C. Battery capacity is increased by 1% for every 1°C increase in temperature up to 25°C.
If a battery is used at temperatures above 25°C, its life is reduced; consequently its capacity and UPS autonomy time
will reduce more rapidly over a period of time. Operating below 20°C will reduce the battery capacity by
approximately 1% to 1.5% per 1°C. For example, if a battery discharge test is attempted during the middle of winter
when the ambient temperature is 5°C the battery capacity will be only 77.5% of its design value and will not satisfy its
specified autonomy time.
Ambient temperature, ventilation, spacing, float voltage and ripple current all affect the battery temperature. Uneven
temperature distribution through the battery string will cause the voltage distribution to be uneven which can also lead
to problems — it is therefore important to maintain an even temperature across the whole battery chain.
Valve-regulated cells are very sensitive to temperature and should be operated at a temperature between 15°C and
25°C. To help sustain this operating temperature range the battery is normally float charged at 2.25V/cell.
When batteries are cabinet-mounted adjacent to the UPS module, it is the battery which dictates the designed
maximum ambient temperature, not the UPS. That is, in the case of valve-regulated cells, the ambient room
temperature should be kept between 15°C and 25°C, and not between 0°C and 40°C (which is the specified main
equipment operating temperature range). Temperature excursions are permissible for short periods of time provided
the average temperature does not exceed 25°C.
6.5.2 Battery Population
The nominal DC bus voltage, and therefore battery float voltage, is set according the module’s rated input and output
voltages, and usually set to 432Vdc (380Vac), 446Vdc (400Vac) or 459V (415Vac). Given that the desired cell float
voltage is 2.25V, this means that a different number of cells are required in each case (see Table 6-1).

Chapter 6 Battery
6.6 Battery Protection
The battery is connected to the UPS through a BCB which is manually closed and electronically tripped through the
UPS control circuitry. If the cells are rack-mounted (or located remote from the main UPS cabinet), the BCB must be
mounted as near as possible to the batteries themselves, and the power and control cables connected to the UPS
using the most direct route possible.
Features of the BCB include:
z Isolation from battery to achieve safety and reliability
z Shortcircuit protection
z Automatic opening in the event of inverter lockup due to battery undervoltage to prevent battery damage caused
by overdischarge
z Tripping by remote emergency power off (EPO) button if installed
z Operation error protection
To achieve the required autonomy time, it may be necessary to parallel battery strings. In which case, the battery
circuit breaker should be placed downstream of all parallel battery strings.
Note: All equipment servicing procedures should be carried out only by trained personnel.
6.7 Battery Connection
6.7.1 Fitting The Batteries
1. In general a minimum space of 10 mm must be left on all vertical sides of the battery block to permit free air
movement around the cells.
2. A clearance of 150 mm should be allowed between the top of the cells and the underside of the shelf above (this is
necessary for monitoring and servicing the cells).
3. When installing the batteries always work from the bottom shelf upwards to prevent raising the center of gravity.
6.7.2 Connecting The Battery
1. All cabinets (or racks) must be earthed.
2. In general it is recommended that the inter-connecting cables be fitted to the batteries within their particular level
before fitting the inter-level connecting cables, followed finally by the cables to the circuit breaker.
3. An insulating shroud should be fitted to each terminal after its connection has been made.
4. When connecting the cables between the battery extremities to the circuit breaker always connect the circuit
breaker end of the cable first.
6.8 Battery Installation
Whatever the type of mounting system selected, the following conditions should be noted (see Figure 6-1):
X Layout of cells:
Whatever battery mounting system is used, the batteries should be laid out in such a manner as to make
simultaneous contact with two exposed live parts having a potential greater than 150V impossible. Where this is not
possible, insulated terminal shields must be installed and insulated cables must be used for connections.
Y Service platform:
The service platform (or duckboard) must be slip-proof, insulated from the floor and be at least one meter wide.
Z Connections:
All connections must be as short as possible.

Note: The control cables from the UPS to the BCB control board must be made using the accessory cable of the BCB,
which is a shielded cable located in a separate conduit to that containing the battery power cables. The cable shield
must be earthed to prevent induced noise affecting the control operation, and a separate safety earth must be
connected between the UPS and BCB box.
6.10 Battery Temperature Sensor (Optional)
A battery temperature sensor (model: TMP12Z) supplied separately from the BCB is connected with the UPS logic
through the BCB control board. For the connection, see Figure 6-5.
With this feature fitted, the nominal float voltage supplied to the battery is adjusted so as to be inversely proportional
to the ambient temperature of the battery cabinet or battery room. This prevents the battery being over charged at
high ambient temperatures.

Chapter 7 “1+N” System
This chapter introduces the installation procedures, operating instructions of the “1+N” system, and the installation of
the dual bus system, of the HIPULSE U UPS.
7.1 General
The system can comprise of up to 6 UPS modules of the same power rating and connected in parallel without the
need for a centralized mains static bypass. Instead the bypass static switches of each UPS share the load when the
system transfers to the mains bypass supply.
From a ‘power’ viewpoint, each module is internally identical to the ‘single module’ configuration. A “1+N” system
requires inter-module control signals to manage the load sharing, synchronizing and bypass switching. The control
signals are connected through the parallel cables, which are multi-way ribbon cables connected between the units of
the system to form a ring.
When three or more modules are to be connected in parallel it is recommended that inductance should be inserted in
the static bypass line. This can be installed internal to the UPS as an option.
7.2 “1+N” System Installation Procedures
The basic installation procedure of a parallel system comprising two or more UPS modules is the same as that of
single module system. This section only introduces the installation procedures specific to the parallel system. The
installation of a parallel UPS must follow the installation procedure for a single UPS module with the additional
requirements detailed in this section.
7.2.1 Preliminary Checks
Be sure that a parallel kit is present and fitted in each of the modules, and that the modules are of the same rating
and with the same software and hardware release.
Warning
To achieve coordinated operation of the modules in the parallel system, it is required to configure each module separately using
background configuration software. This must be done by Emerson service & support trained personnel.

maintenance bypass interlock protection for the UPS. Short circuit means external bypass closed.
EXT-Out (X3-3&4) on UPS parallel board M3 (leave shorted if no external output switch is used) provides external
output interlock protection for paralleled UPS modules. Short circuit means external output switch closed.
Note
UPS parallel board M3 is located behind protective covers accessible aftr opening the UPS front door — removal of this barrier
requires the use of a tool and is restricted to service personnel.
Jumper JP1 (located next to X3) needs to be removed for X3: 3&4 to work properly.
7.3 “1+N” System Operating Instructions
Warning
If residual current detectors (RCDs) are used on UPS unit inputs, use a common device only on the system’s bypass mains. At
the instant of electrical connection, the current may not be split instantaneously and this may cause the residual current circuit
breakers (RCCBs) to trip separately.
These operations must be performed one at a time, progressing to the next step only after having completed the
previous step on both UPS modules.

7.3.1 Start-Up Procedure (Into Normal Mode)
This procedure must be followed when turning on the UPS from a fully powered down condition, that is, where the
load is not being initially supplied at all or where supplied by the maintenance bypass switch. It is assumed that the
installation is complete, the system has been commissioned by authorized personnel and the external power isolators
are closed.
Refer to 5.2
Start-Up Procedure (Into Normal Mode).
7.3.2 Maintenance Bypass Procedure (And UPS Shut Down)
Warning
The internal maintenance bypass must not be used when the UPS system is comprised of more than two UPS modules in
parallel.
Refer to 5.6
Maintenance Bypass Procedure (And UPS Shut Down).
7.3.3 Switching OFF And Isolating One UPS While The Other Remains In Service
1. In sequence, open the UPS output switch Q5, input switch Q1, and bypass switch Q2.
2. Open the BCB inside the battery cabinet.
To completely isolate the UPS, open the AC power supply circuit breaker (both circuit breakers if separate supplies
are provided for the rectifier and the bypass supply) and the output circuit breaker on the power distribution
switchboard.
If individual UPS output isolation circuit breaker (and its auxiliary contacts) are not installed on the power distribution
switchboard, remember that voltage supplied by the others UPS which remains in service will still be present on the
output terminals of the shutdown UPS.
Warning
If individual UPS output isolation circuit breaker are not installed on the power distribution switchboard, remember that voltage
supplied by the others UPS which remains in service will still be present on the output terminals of the shutdown UPS.
Warning: Wait five minutes for the internal d.c bus bar capacitors to discharge.
7.3.4 Insertion Procedure (Of One Module In A Parallel System)
This procedure is indicated to re-integrate a UPS module that has been previously isolated from other modules of a
group of paralleled UPS modules. It is assumed that the installation is complete, the system has been commissioned
by authorized personnel and the external power isolators are closed.
1. Open the UPS door to gain access to the power switches.
2. Open (or confirm disabled) maintenance bypass switch Q3.
3. Close the bypass switch Q2, output switch Q5, and any external output isolation switches (where used). The LCD
display becomes active.
4. Close the input switch Q1.
The rectifier LED flashes on the operator control and display panel during the startup of rectifier and becomes steady
green once the rectifier reaches normal operation state after about 15 seconds.
5. Close the external BCB. This breaker is located inside the battery cabinet (if used) or is otherwise adjacent to the
battery racks.
6. Following battery availability being detected by the UPS, the red battery LED extinguishes moments after when the
battery charger starts operation.
7. Press and hold the INVERTER ON button for two seconds.
The inverter will start up and the inverter LED flashes while it synchronizes to the load voltage frequency. After the
inverter is ready, the UPS connects to the load, the inverter LED becomes steady green and the load LED turns
green.

7.4 Dual Bus System Installation Procedures
7.4.1 Cabinet Installation
As shown in Figure 7-3, the dual bus system consists of two independent UPS configurations each consisting of one
or more UPS modules. Dual bus systems are high availability configurations suitable for loads with multiple input
terminals. For single input loads an optional static transfer switch (STS) may be added.
The objective of the dual bus system is to keep the output of two independent UPS systems (or parallel systems) in
synchronization using optional load bus synchronization (LBS) cable. One system is designated as the master; the
other is designated as the slave. The operating modes covered comprise master and or slave operating inverter or
bypass mode.

If the dual bus system consists of two single units, use the optional 9-core LBS cable to connect between the LBS
interfaces (X4 socket on parallel board) of the two single units, and use another optional LBS cable to connect
between any two 25-core interfaces (X2-1 or X2-2) of the two single units, as shown in Figure 7-4.
Warning
Although the dedicated 25-core LBS cable looks like the parallel cable, it is absolutely not the parallel cable, and cannot be
replaced by it. Otherwise, UPS system chaos may occur.

Chapter 9 Service & Maintenance
Chapter 9 Service & Maintenance
Regular service and maintenance are required during the long term operation of the UPS system (including the
associated battery). The battery maintenance is expounded in chapter 6. This chapter deals with the life
characteristics of the key components of the UPS, and provides recommendation for the regular check and service of
the key components. Proper service and maintenance of the UPS system can extend the UPS life and reduce the risk
of system malfunction.
9.1 Safety
Warning
The daily patrol check of the UPS system can be conducted by trained personnel, while the check and replacement of the UPS
components should be done by authorized professionals.
9.2 UPS Key Components And Their Lives
During the UPS operation, some UPS components’ lives are shorter than the UPS life due to wear and tear in
working. To ensure the safe power supply of the UPS system, regular check and replacement of these components
are required. This section introduces the key components of the HIPULSE U series UPS and their reference working
lives. For systems working in different conditions (environment, load, and so on), you may ask professionals to
assess the components and provide advices whether to replace the components by referring to the information
provided in this section.
9.2.1 Magnetic Components: Transformer, Inductor
The design life of the magnetic components is 20 years. The key factors affecting the life of the magnetic components
are the interwinding isolation system and the temperature increase in operation. The HIPULSE U series UPS adopts
H-level isolation system and can withstand up to 220°C working temperature. Normally, the UPS works in forced air
cooling condition.
9.2.2 Power Semiconductor Devices
The power semiconductor devices include SCR (silicon-controlled rectifier) and IGBT (insulated gate bipolar
transistor). In normal UPS working condition, there is no rated life of the power semiconductor devices. The SCR and
IGBT failures are always caused by other problems, as they do not have the problem of life expiration. However, in
system service and maintenance, you should check on an annual basis the appearances of the power semiconductor
devices for erosion and damage. If you spot any risk of failure , replace the device.
9.2.3 Electrolytic Capacitors
The life of the electrolytic capacitors depend on the DC bus voltage and ambient temperature of the UPS.
To ensure safe and stable UPS operation, it is recommended to check the operation status of the electrolytic
capacitors on an annual basis. The electrolytic capacitors must be replaced before their life expires, advisably, within
5 to 6 years of operation.
9.2.4 AC Capacitors
It is recommended to replace the AC capacitors within 5 to 6 years of continuous operation, and to check the AC
capacitors on a half year basis. Replace the AC capacitor if spotting any deformation.

9.2.5 Lives And Recommended Replacement Time Of Key Components
The key components listed in Table 9-1 are used in the UPS. To prevent system malfunction caused by failure of key
components due to wear and tear during working, you are recommended to check them regularly, and replace them
within their life expectancy.

9.2.6 Replacing Fuses
When replacing the fuse on the high-voltage interface board or the fuse in the fuse box, use a fuse of the same model,
avoid being misled by the parameter screenprint on the fuse box.
380V systems can use both 380V/4A fuse and 500V/4A fuse, while 400V/415V systems can use 500V/4A fuse only.
