Debugging & Operating
DANGER
Make sure the grounding cable is well connected before
connecting the power cables. The grounding cable and neutral
cable must comply with the local and national codes of
practice.
Before moving or reconnecting the cables, ensure that all input
power sources are cut off, and wait at least 10 minutes for
internal discharge. Use a multimeter to measure the voltage
on the terminals, and ensure the voltage is lower than 36 V
before operation.
ATTENTION
Before the UPS is powered (for both mains line and battery
line connections), earth connection must be made.
Earth leakage current that is introduced by the UPS
(configurations from 10 kW to 40 kW) is to exceed 3.5 mA and
must not exceed 1000 mA, and must comply with the
requirements of IEC/EN 62040-1 / IEC/EN 60950-1. When
selecting residual current circuit breakers (RCCB) or RCD
devices, transient and steady-state earth leakage currents that
may occur during equipment start-up should be considered.
RCCBs must be selected that are sensitive to DC
unidirectional pulses (class A) and insensitive to transient
current pulses.
Earth leakage currents of the load will be carried by the RCCB
or RCD.
This equipment must be grounded in accordance with local
electrical authority codes of practice.
Initial check and inspection should be performed after longterm storage of the UPS.
Maintenance & Replacement
DANGER
All equipment maintenance and servicing procedures involving
internal access require special tools, and should be carried out
only by trained personnel. The components that can only be
accessed after the protective cover has been opened (with
tool) cannot be serviced by user.
This UPS is compliant with IEC 62040-1 regarding the general
and safety requirements for UPS. Dangerous voltages are
present in the battery box. However, the risk of contact with
these high voltages is minimized for non-service personnel.
Since the high-voltage component can only be touched when
the protective cover is opened (with tool), the possibility of
contact with the high-voltage component is minimized. There
are no risks to personnel if the equipment is operated normally
as per the operating procedure recommended in this manual.

Battery Safety
DANGER
All the battery maintenance and servicing procedures involving
internal access need special tools or keys, and should be
carried out only by trained personnel.
WHEN CONNECTED, THE BATTERY TERMINAL VOLTAGE
WILL EXCEED 400 Vdc AND IS POTENTIALLY FATAL.
Battery manufacturers supply details of the necessary
precautions to be observed when working on, or near, a large
bank of battery cells. These precautions should be followed
explicitly at all times. Attention should be paid to the
recommendations concerning local environmental conditions
and the provision of protective clothing, first aid and firefighting equipment.
Ambient temperature is a major factor in determining battery
capacity and battery life. The nominal operating temperature of
the battery is between 20°C and 25°C. Operating out of this
temperature range will reduce battery life. To ensure UPS
back-up time, the battery should be changed periodically, as
indicated in the battery user manuals.
Replace the batteries only with the same type and number of
battery. A different type of battery could cause an explosion or
poor performance.
When connecting the battery, follow the precautions for highvoltage operation. Before accepting and using the battery,
check the appearance of the battery. If the package is
damaged, or the battery terminal is dirty, corroded or rusted, or
if the shell is broken, deformed or leaks, replace it with a new
product. Otherwise, the damage could reduce battery capacity,
or cause electrical leakage or fire.
Remove any rings, watches, necklaces, bracelets or other
metal jewelry before operating the battery.
Wear rubber gloves.
Eye protection should be worn to prevent injury from
accidental electric arcs.
Only use tools (e.g. wrench) with insulated handles.
The batteries are very heavy. Please handle and lift the battery
properly to prevent human injury, or damage to the battery
terminal.
Do not disassemble, modify or damage the battery. Otherwise,
battery short circuits, leakage or even human injury may be
caused.
The battery contains sulfuric acid. During normal operations,
the sulfuric acid soaks into the fiber between the plates of the
battery. However, when the battery case is broken, the acid
will leak from the battery. Therefore, be sure to wear protective
glasses, rubber gloves and an apron when operating the
battery. If not, acid could get into your eyes, which could lead
to blindness or skin damage.
At the end of battery life, the battery may have an internal
short circuit, a discharge of electrolytes and a corrosion of
positive/negative plates. If this condition continues, the
temperature may become uncontrollable, and the battery may
swell or leak. Be sure to replace the battery before these
phenomena occur.
If a battery leaks electrolytes, or is otherwise physically
damaged, it must be replaced, stored in a container resistant
to sulfuric acid, and disposed of in accordance with local
8000064255 BAL, en
Page 9 of 72
Installation & User manual
regulations.
If electrolytes come in contact with the skin, the affected area
should be washed immediately with water.
Disposal
WARNING
Dispose of used battery according to the local regulations.

1.2
Initial Check
Perform the following checking operations prior to UPS installation.
- Visually examine if any damage has been done to the interior
and exterior of the UPS rack or battery equipment as a result
of transport. Report any such damage to the shipper
immediately.
- Verify the product label and confirm that the equipment is
correct. The equipment label is attached on the back of front
door. The UPS model, capacity and main parameters are
marked on the label.
1.3
Location
1.3.1
UPS Location
The UPS is intended for indoor installation and should be placed in
a cool, dry and clean environment with adequate ventilation to
keep the environmental parameters within the specified operating
range (see Technical Data sheet). The modular UPS series uses
forced convection cooling by internal fans. Cooling air enters the
module through ventilation grills located at the front part of the
cabinet, and exhausted through grills located in the rear part of the
cabinet. Please do not block the ventilation holes.
If necessary, a system of extractor fans should be installed to aid
cooling airflow. An air filter should be used when the UPS is to
operate in a dirty environment, and should be regularly cleaned to
maintain airflow. The cooling capacity of the air conditioner should
be selected in compliance with the power loss data of the UPS
specified in Technical Data sheet: Normal mode (VFI SS 111
double-conversion UPS).
Note: The UPS should be installed on a cement surface or other
surface that is not flammable.
1.3.2
External Battery Room
The battery will generate some hydrogen and oxygen at the end of
charging, so the fresh air volume of the battery installation
environment must meet EN50272-2001 requirements.
The ambient temperature of the battery must be stable. Ambient
temperature is a major factor in determining the battery capacity
and life. The nominal operating temperature of the battery is 20°C.
Operating above this temperature will reduce battery life, and
operation below this temperature will reduce battery capacity. If the
average operating temperature of the battery is increased from
20ºC to 30ºC, then the service life of the battery will be reduced by
50%. If the operating temperature of the battery is above 40ºC,
then the battery service life will decrease exponentially. In a
normal installation, the battery temperature is maintained between
15°C and 25°C. Keep batteries away from heat sources or air
outlets.
If external batteries are to be used, the battery circuit breakers (or
fuses) must be mounted as close as possible to the batteries, and
the connecting cables should be as short as possible.

8000064255 BAL, en
Installation & User Manual
1.3.3
Storing
Should the equipment not be installed immediately, it must be
stored in an indoor location to protect it from excessive humidity
and heat (see Technical Data sheet). The battery needs to be
stored in a cool and dry place with good ventilation. The most
suitable storage temperature is 20ºC to 25ºC.
ATTENTION
Preventing deep discharge of battery
Should the UPS remain unpowered for a prolonged period
while the batteries are being connected, there is a risk of deep
discharge and thus of permanent damage to the batteries. In
such a case, it is recommended to leave the battery circuit
breaker(s) open. In any case, periodically charge the battery
during storage as per the battery user manuals.
1.4
Positioning
When the equipment has been finally positioned, ensure that the
UPS will remain stationary and stable. To prolong service life,
chose a place that will ensure:
- space for easy operation on the UPS
- sufficient air to dispel heat produced by UPS
- protection against atmospheric agents
- protection against excessive humidity and heat
- protection against dust
- compliance with the current fire prevention requirements
- maximum efficiency relative to temperature, as the batteries
have a maximum efficiency when they are kept at a
temperature in the same range as the operating environment
of between +20°C to +25°C. For information on battery
storage, transportation and environment, refer to Technical
Data sheet.
- that the equipment has a steel frame structure with removable
panels. The top and side panels are fixed by screws.
- that after opening the UPS rack door, the auxiliary
connections for external low voltage interface and
maintenance bypass can be accessed. The UPS rack has an
operating and control panel located on its front door, which
provides basic operating status and alarm signal information.
Batteries are external. The UPS provides an air inlet port in
the front and an air exhaust port in the rear.
1.4.1
System Cabinet
Depending on the specific system requirements, a UPS system
can be comprised of a UPS rack and an external battery cabinet.
Refer to Chapter 4: Installation drawing for the positioning of the
UPS cabinet.
8000064255 BAL, en
Page 13 of 72
Installation & User manual
1.4.2
Moving the Cabinets
WARNING
Ensure that any lifting equipment used in moving the UPS
cabinet has sufficient lifting capacity. The UPS is fitted with
castors – take care to prevent movement when unbolting the
equipment from its shipping pallet. Ensure that adequate
personnel and lifting aids are available when removing the
shipping pallet.
Ensure that the UPS weight is within the weight-loading capacity
range of any hoisting equipment. See Technical Data sheet for
UPS weight.
The UPS and optional cabinets can be handled by means of a fork
lift or similar equipment. For short distances, the UPS cabinet can
also be moved on its castor rollers.
Note: Units equipped with batteries must be handled with care.
Keep such moves to a minimum.
1.4.3
Clearances Required for Operating
As the UPS rack module has no ventilation grills at either side, no
clearances are required for the sides.
To enable routine tightening of power terminations in the UPS, it is
recommended that clearance at the front of the equipment should
be sufficient to enable free passage of personnel when the doors
are fully opened. It is important to leave 500mm at the rear of the
rack to permit adequate circulation of air coming out of the unit.
If the UPS uses an internal modular battery, sufficient clearance
should be provided at the rear to allow personnel to operate the
battery circuit breakers.
1.4.4
Front Access
The component layout of the UPS rack system supports front
access of the UPS for repairs, which thus reduces the space
requirement for side access.
1.4.5
Final Positioning
When the equipment has been finally positioned, ensure that the
adjustable feet are fixed so that the UPS will remain stationary and
stable.
1.4.6
Installation of Adjustable Feet
Installation diagrams in Chapter 4 of this manual identify the
location of the holes in the base plate, where the equipment can
be bolted to the floor. If the UPS is to be located on a raised floor,
it should be mounted on a pedestal to assume the center point
load of the UPS (more than 150 kg).

If cables do not fit through the holes, they should be fed in through
cover. In this case, block the remaining space to protect the UPS
from small rodents entering.
1.5
External Protective Devices
For safety purposes, it is necessary to install external circuit
breakers or other protective devices for the AC input supply of the
UPS system. This section provides general, practical information
for qualified installation engineers. The installation engineers
should have knowledge of regulatory wiring standards, and of the
equipment to be installed.
1.5.1
Rectifier and Bypass Input Supply of the UPS
Overcurrent
Install suitable protective devices in the distribution unit of the
incoming mains supply, taking into considering the power-cable
current load capacity and overload capacity of the system.
Generally, an IEC60947-2 magnetic circuit breaker is
recommended that has a C (normal) tripping curve at 125% of the
current listed in the Technical Data sheet. Split bypass: If a split
bypass is used, separate protective devices should be installed for
the rectifier input and bypass input in the incoming mains
distribution panel.
Note: The rectifier input and bypass input must use the same

Protection against earth faults (Residual Circuit Breaker, RCB
devices):
The RCB device installed upstream of the input supply should:
- be sensitive to DC unidirectional pulses (class A) in the
network
- be insensitive to transient current pulses
- have an average sensitivity that is adjustable between 0.3A
and 1A.
Fig.1- 5: The RCB symbols
When using the RCB in the separated bypass system or the
parallel connection, the RCB should be installed upstream to the
input distribution to avoid incorrect alarm signals.
The residual current introduced by the RFI filter in the UPS is
between 3.5 mA and 1000 mA. It is recommended that the
sensitivity of the RCD of the upstream input distribution and
downstream distribution (to load) be confirmed.
1.5.2
External Battery
The DC-compatible circuit breaker provides overcurrent protection
for the UPS system and the battery, which is provided by the
external battery cabinet.
1.5.3
UPS Output
If an external distribution panel is used for load distribution, the
selection of protective devices must be distinct from those that are
used at the input to the UPS.
1.6
Power Cables
The cables should be designed as described in this section, and
comply with local regulatory wiring standards. Environmental
conditions (temperature and physical support media) should also
be taken into consideration. Refer to IEC60950-1 Table 3B:

Input current of common input configurations of rectifier and
bypass
Take special care when determining the size of the output and
bypass neutral cable, as the current circulating on the neutral
cable may be greater than nominal current in the case of nonlinear loads, which is usually 1.732 times rated currents.
The earth cable connecting the UPS to the main ground
system must follow the most direct route possible. The earth
conductor should be sized as per the fault rating, cable
lengths, type of protection, etc.
In compliance with AS/IEC60950-1, the cross-section area of
the conductor is 16mm2/10mm2 (30/40kVA input/output), the
cross-section area of the conductor is 10mm2/6mm2
(15/20KVA input/output),
When sizing battery cables, a maximum volt drop of 4Vdc is
permissible at the current ratings given in Table 1-2. The load
equipment is connected to a distribution network of individually
protected busbars fed by the UPS output rather than
connected directly to the UPS.
In parallel multi-module systems, the output cable of each
UPS unit should be kept at equal length between the output
terminals and the parallel distribution bus bar, in order to avoid
affecting the shared current. When laying the power cables,
do not form coils, to avoid electromagnetic interferences.
When laying the power cables, do not form coils, to avoid the
formation of electromagnetic interference.

If an external emergency stop facility is required, it is connected
via the reserved terminals of J4. The external emergency stop
facility needs to use shielded cables to connect to the normally
open/closed remote stop switch between these two pins. If this
facility is not used, then pin 3 and pin 4 of J4 must be open, or pin
1 and pin 2 of J4 must be shorted.
The emergency stop action within the UPS will shut down the
rectifier, inverter and static bypass. However, it does not
internally disconnect the mains input power supply. To
disconnect ALL power to the UPS, open the upstream input
circuit breaker(s) when the EPO is activated.
Pin 1 and 2 of J4 have been short-circuited before the UPS is

Battery Installation and Maintenance
2.1
General Recommendations
Take special care when operating the batteries of the modular
UPS system. When all the battery cells are connected, the battery
voltage can exceed 400Vdc, which is potentially fatal.
i
The precautions for battery installation, use and
maintenance are to be provided by the battery
manufacturers. The precautions in this section include key
issues to be considered when designing the installation, and
may be adjusted according to the specific local situations.
WARNING
Battery Room Design
The battery is to be installed and stored in a clean, cool and
dry environment.
Do not install the battery in a sealed battery chamber or sealed
room. The battery room ventilation should at least meet the
requirements of EN 50272-2001. Otherwise, battery bulging,
fire and even human injury may be caused.
The battery is to be installed at a good distance from the
heating source (e.g. transformer). Do not use or store the
battery in a place near the heating source, do not burn the
battery, or put it in a fire. This could cause battery leakage,
bulging, fire or explosion.
Batteries should be arranged in such a way that two bare live
parts with a potential difference of more than 150 V will not be
contacted at the same time. If this is unavoidable, use
insulated terminal covers and insulated cables for connection.
If external batteries are to be used, the battery circuit breakers
(or fuses) must be mounted as close as possible to the
batteries, and the connecting cables should be as short as
possible.

Installation & User Manual
WARNING
Battery Handling
When connecting the battery, follow the precautions for highvoltage operation:
Before accepting and using the battery, check the appearance
of the battery. If the package is damaged; if the battery
terminal is dirty, corroded or rusted; or if the case is broken,
deformed or has leakages, replace it with a new product.
Otherwise, this could result in battery capacity reduction,
electric leakage or fire.
Before operating the battery, remove rings, watches,
necklaces, bracelets and any other metal jewelry
Wear rubber gloves
Wear eye protection to prevent injury from accidental electric
arcs
Only use tools (e.g. wrench) with insulated handles
The batteries are very heavy. Please handle and lift the
batteries properly to prevent human injury or damage to the
battery terminal.
Do not modify, damage or decompose the battery. Otherwise,
battery short-circuits, leakages or even human injury may
occur.
The battery contains sulfuric acid. During normal operations,
the sulfuric acid soaks into the fiber between the plates of the
battery. However, when the battery case is broken, the acid
will leak from the battery. Therefore, be sure to wear protective
glasses, rubber gloves and an apron when operating the
battery. If not, acid could get into your eyes leading to
blindness or skin damage.
At the end of battery life, the battery may have an internal
short circuit, an electrolyte discharge, or corrosion of
positive/negative plates. If the condition continues, the
temperature may become uncontrollable, and the battery may
swell or leak. Be sure to replace the battery before these
phenomena occur.
If a battery leaks an electrolyte, or is otherwise physically
damaged, it must be replaced, stored in a container resistant
to sulfuric acid and disposed of in compliance with local
regulations.
If electrolytes come into contact with the skin, the affected
area should be washed immediately with water.

2.2
Battery Typologies
Depending on the required configuration, the UPS may need
batteries consisting of one or more strings of battery blocks
installed on shelves in a locked cabinet or in a designated battery
room.
Between 32 and 44 batteries per string (even numbers) can
be installed in a conventional battery cabinet (external).
If the unit is ordered without internal batteries, the default
factory setting is 40.
The cabinet can only be used with valve-regulated,
maintenance-free, lead-acid batteries.
CAUTION: The lead-acid battery may cause chemical risks.
i
2.2.1
Traditional Battery Installation
Only qualified engineers can install and service batteries mounted
in a conventional battery cabinet or shelf. To ensure safety, install
the external batteries in a locked cabinet or designated battery
room that is accessible to service qualified personnel only.
Please note that the number of cells set via software must be
consistent with the actual number of cells.
A minimum space of 10 mm must be reserved on all vertical sides
of the battery block to permit free air movement around the cells.
A certain clearance should be reserved between the top of the
cells and the underside of the upper shelf, as this is necessary for
monitoring and servicing the cells.
When installing the batteries, always work from the bottom shelf
upwards to prevent shifting of the center of gravity.
Install the batteries reliably avoiding vibrations and bumping.
The bending radius of the cable should exceed 10D, with "D"
representing the outer diameter of the cable.
When connecting the cables, do not cross the battery cables and
do not bind the battery cables together. The battery connection
must be firm and stable. After connecting the cables, all
connections between the wiring terminals and the batteries must
be adjusted to meet the torque requirement provided in the
specifications and user manuals of the battery manufacturers.
All battery terminals should be insulated after their connections
have been made.
Check if the battery is unexpectedly grounded. If this is the case,
remove the earth power supply. Contact with any part of the
grounded earth may lead to electric shock.
Measure the battery voltage, and carry out battery voltage
calibration after the UPS is started.

Introduction
The modular UPS rack system provides the critical load (such as
communication and data processing equipment) with high quality
uninterruptible AC power. The power from the UPS is free from
voltage and frequency variations and disturbances (interruptions
and spikes) experienced at the mains AC input supply.
This is achieved through high frequency double conversion power
pulse width modulation (PWM) associated with fully digital signal
processing control (DSP), which features high reliability and
convenience for use.
As shown in Fig. 5-1, the AC input mains source is supplied at the
UPS input and converted into a DC source. This DC source feeds
the inverter that converts the DC source into a clean and input
independent AC source. The battery powers the load through the
inverter in case of an AC input mains power failure. The utility
source can also power the load through the static bypass.
When the UPS needs maintenance or repair, the load can be
transferred to maintenance bypass without interruption, and the
power module and bypass module can be removed for
maintenance.

5.1.1
Split-Bypass Input
Fig. 5-1 illustrates the modular UPS in what is known as the splitbypass configuration (i.e., the bypass uses a separated AC
power). In this configuration, the static bypass and maintenance
bypass share the same independent bypass power supply and
connect to the power supply through a separate switch. Where a
separated power source is not available, the bypass and rectifier
input supply connections are linked.
5.1.2
Static Transfer Switch
The circuit blocks labeled “static switch” in Fig. 5-1 contain
electronically controlled switching circuits that enable the critical
load to be connected to either the inverter output or to a bypass
power source via the static bypass line. During normal system
operation, the load is connected to the inverter; but in the event of
a UPS overload or inverter failure, the load is automatically
transferred to the static bypass line. To provide a clean (no-break)
load transfer between the inverter output and static bypass line,
the inverter output and bypass supply must be fully synchronized
during normal operating conditions. This is achieved via 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 incorporated
into the UPS design. It enables the critical load to be powered from
the utility (bypass) supply while the UPS is shut down for routine
maintenance.

5.2
When the UPS is operating in bypass mode or on
maintenance bypass, the connected equipment is not
protected from power failures or surges and sags..
Parallel System
Up to 4 UPS frames can make a parallel system, with the purpose
of providing additional power or reliability (N+1 parallel
redundancy). The load will be equally shared between any
paralleled UPS.
5.2.1
Features of Parallel System
-
-
-
5.2.2
The hardware and firmware of single module UPS units are
completely compatible with the requirements of a parallel
system. Parallel configuration can be achieved merely through
settings in configuration software. The parameters settings for
the modules in parallel system shall be consistent.
Parallel control cables are connected in a ring, providing both
performance and redundancy. Dual-bus control cables are
connected between any two UPS modules of each bus. The
intelligent paralleling logic provides the user with maximum
flexibility. For example, shutting down or starting up UPS
modules in a parallel system can be done in any sequence.
Transfers between Normal and Bypass modes of operation
are synchronized and self–recovering e.g. following overloads
and their clearance.
The total load of the parallel system can be queried from each
unit’s LCD.
Parallel Requirements of UPS Modules
A group of paralleled modules behave as if it were one large UPS
with the advantage of presenting higher reliability. In order to
assure that all modules are equally utilized and to comply with
relevant wiring rules, the following requirements apply:
- All UPS modules shall be of the same rating and must be
connected to the same bypass source.
- The bypass and the main input sources must be referenced to
the same neutral potential.
- Any RCB, if installed, must be of an appropriate setting and
located upstream of the common neutral bonding point.
Alternatively, the device must monitor the protective earth
currents of the system. Refer to the High Leakage Current
Warning in the first part of this manual.
- The outputs of all UPS modules must be connected to a
common output bus.
- It is strongly recommended that each paralleled UPS install at
least a redundant power module

Optional isolation transformers must be connected
for applications where different input sources do not
share the same neutral reference or where the
neutral is not available.

Parallel system is available up to 4 frames.

Operating Mode
The modular UPS is an on-line, double-conversion, reversetransfer UPS that permits operation in these modes:
- Normal mode
- Battery mode
- Auto-restart mode
- Bypass mode
- Maintenance mode (manual bypass)
- Parallel redundancy mode
- ECO mode
5.3.1
Normal Mode
The UPS inverter power modules 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.
5.3.2
Battery Mode
Upon failure of the AC mains input power, the inverter power
modules, which obtain power from the battery, supply the critical
AC load. There is no interruption in power to the critical load upon
failure. After restoration of the AC mains input power, the “Normal
Mode” operation will continue automatically without the necessity
of user intervention.
5.3.3
Auto-Restart Mode
The battery may become exhausted following an extended AC
mains failure. The inverter shuts down when the battery reaches
the end of discharge voltage (EOD). The UPS may be
programmed to “Auto Recovery after EOD” after a delay time if the
AC mains recovers. This mode and any delay time are
programmed by the commissioning engineer.
5.3.4
Bypass Mode
If the inverter overload capacity is exceeded under normal mode,
or if the inverter becomes unavailable for any reason, the static
transfer switch will perform a transfer of the load from the inverter
to the bypass source, with no interruption in power to the critical
AC load. Should the inverter be asynchronous with the bypass, the
static switch will perform a transfer of the load from the inverter to
the bypass with power interruption to the load. This is to avoid
large cross currents due to the paralleling of unsynchronized AC
sources. This interruption is programmable but typically set to be
less than 3/4 of an electrical cycle, e.g., less than 15ms (50Hz) or
less than 12.5ms (60Hz).
5.3.5
Maintenance Mode (Manual Bypass)
A manual bypass switch is available to ensure continuity of supply
to the critical load when the UPS becomes unavailable e.g., during
a maintenance procedure.
Page 42 of 72
8000064255 BAL, en
Installation & User Manual
5.3.6
Parallel Redundancy Mode (System Expansion)
For higher capacity or higher reliability, the outputs of several UPS
(up to 4 Protect Plus M400) can be programmed for direct parallel
while a built-in parallel controller in each UPS ensures automatic
load sharing.
5.3.7
Eco Mode
To improve system efficiency, the UPS rack system works in
bypass mode at normal time, and the inverter is on standby. When
utility fails, UPS transfers to battery mode, and the inverter powers
the loads. The efficiency of the ECO system can be up to 98%.
NOTE: There is a short interruption time (lower than 10ms) during
the transfer from ECO to battery mode, so ensure that the time has
no effect on loads.

If you need to completely power down the UPS, use the following
procedure:
- Press EPO button on the front panel
- Open external battery breaker and internal battery breaker
- Open bypass breaker, external input breaker, external output
breaker
If the rectifier and bypass use different power supplies, you will
need to open the two input breakers respectively.
6.5
EPO Procedure
The EPO button is designed to switch off the UPS in emergency
conditions (e.g., fire, flood, etc.). To do this, just press the EPO
button and the system will turn off the rectifier and inverter, and
stop powering the load immediately (including the inverter and
bypass), and the battery will stop charging or discharging.
If input power supply is available, the UPS control circuit will
remain active; however, output will be turned off. To completely
isolate the UPS, you will need to open the mains input breaker and
battery breaker.
6.6
Auto Start
Commonly, the UPS rack is started up on static bypass. When the
mains power fails, the UPS draws power from the battery system
to supply the load until the battery voltage reaches the end of
discharge (EOD) voltage, and the UPS will shut down.
The UPS will automatically restart and enable output power:
- after the mains power is restored
- if auto recovery-enabling feature is enabled after EOD
6.7
UPS Reset Procedure
After using EPO to shut down the UPS, operate as follows to
restore UPS:
- Shut down UPS completely
- Start UPS as in Section 6.2.1
If the UPS is shut down due to excessive temperature, switching,
or overload of the inverter, the UPS will reset the fault
automatically when fault is cleared.
i
The rectifier will be turned on automatically when the
overtemperature fault disappears (after overtemperature
signals have disappeared).
After pressing the EPO button, the UPS will be completely
powered down if the UPS mains input has been disconnected.
When the mains input is restored, the EPO status will be cleared,
and the UPS system will enable static bypass mode to restore the
output.
WARNING

Fan fail
Description
At least one fan fails in the N# power module.
Output overload
The N# power module output is on overload. This signal appears
when the load rises above 100% of nominal rating. The alarm
automatically resets once the overload condition is removed.
1. Check which phase has overloaded by the load (%) displayed
in the LCD to confirm if this signal is correct.
2. If the signal is correct, measure the actual output current to
confirm if the displayed value is correct.
Disconnect the non-critical load.
Inverter overload t
out
N# power module inverter in overload has timed out. The UPS
overload status continues and the overload times out.
Note: The highest loaded phase will indicate overload timing-out
first.
When the timer is active, then the alarm “unit over load” should
also be active as the load is above nominal.
When the time has expired, the inverter switch is opened and
the load transferred to bypass.
If the load decreases to lower than 95%, after 2 minutes, the
system will transfer back to inverter mode. Check the load (%)
displayed in LCD to confirm if this alarm is true. If LCD displays
that overload has occurred, then check the actual load and
confirm if the UPS was in overload before signal appeared.

signal disappears.
If over temperature exists, check whether:
the ambient temperature is too high,
the ventilation channel is blocked,
there is a fan fault,
the inverter overload time is out.
