Introduction
The product described in this manual is a transformerless Uninterruptible Power System
(UPS). It is a true online, continuous duty, double conversion, static state, three-phase system,
providing conditioned and uninterruptible AC power to protect the customer’s load from all
nine power failures.
2.1 System description
The UPSs are used to protect sensitive IT equipment and prevent loss of valuable electronic
information, minimise equipment downtime, and minimise the adverse effect on production
equipment due to unexpected power problems.
The UPS system continually monitors incoming electrical power and removes the surges,
spikes, sags, and other irregularities that are inherent in commercial utility power. Working
with a building‘s electrical system, the UPS system supplies clean, consistent power that
sensitive electronic equipment requires for reliable operation. During brownouts, blackouts, and
other power interruptions, batteries provide emergency power to safeguard operation.
The UPS system is housed in single freestanding cabinets. The cabinets line up and match in
style and colour, and have safety shields behind the doors for hazardous voltage protection.

2.2 Feature: Active-Front Technology
Traditional input THD filters are no longer needed with this UPS product. The build-in
advanced rectifier technology of UPS modules provides perfect sinusoidal input power quality at
0.99 input power factor with harmonic content less than 5% THD(i). This leads to more reliable
total system operation and savings in generator and transformer sizing as losses in the windings
are minimised.
Due to the active front rectifier, the UPS is comparable to a clean resistor load from the mains
perspective. Thus, the high input power factor provides minimised cabling and fusing costs due
to no reactive power consumption.
The low harmonic currents are due to high input power factor and provide the benefits:
•
•
•
•
•
No additional losses in wires and cables
No extra heating of transformers and generators with shortened service life
No false circuit breaker tripping and malfunction
No erratic operation of computers, telecommunication, monitors, electronic test equipment
etc.
No Resonance with power factor correction capacitors
2.3 Feature: Advanced Battery Management (ABM)™
The ABM monitors the status of the battery and charges it only when the battery needs
charging. This is the key to long battery life with the ABM due to low generation of corrosion
inside the battery. It also monitors that the load never crashes because of bad or defected battery.
The main cause for corrosion is current flowing through battery. The more current going
through battery, the shorter the battery life. Current flows through battery when it is discharged
or charged. There is very little that can be done for discharging, because it depends on number
of power outages in utility line.
The ABM is very valuable feature since most of the time battery does not need any charging.
The charging is controlled and initiated on the following occasions:
-
-
-
When turning the unit on
After 18 days without charging
If the open cell voltage decreases below predetermined voltage level
Hence, the function of ABM system is to prolong the battery life considerably compared to
traditional system that uses float-charging technology. This means that there is no current going
through batteries all the time and causing corrosion. In a traditional online UPS the inverter
also causes ripple-current to be fed to batteries causing corrosion.
2.4 Feature: Hot Sync® technology
The UPS product features U.S. #5,745,365 patented paralelling technology that provides N+X
redundancy without introducing a single-point-of-failure. The products utilising the Hot Sync
are completely autonomous and the only thing common among them is the critical output
power bus.
The Hot Sycn is 100% mathematical firmware that makes it more reliable than traditional
paralleling techniques. Because the solution is implemented intrinsically, and Hot Sync is always
active, the UPS modules do not know whether or not they are even in parallel.

Revision C
A parallel UPS system means the linking together of two or more UPS units in parallel so that in
the unlikely event one fails the other can automatically take up the load. Traditionally a parallel
redundancy configuration is achieved by having a random or fixed master-slave relationship
among the UPS units. This master logic gives out individual commands to all the slaves
units. Unfortunately this can lead to a single-point-of-failure for the whole system because if
the master logic or communication to slaves fails, and causes the whole UPS system to be in
trouble.
The Hot Sync® technology was developed to allow parallel capacity system and to maintain
the highest system availability. An industry leading paralleling technology in its own right,
the patented Hot Sync enables you to set up a parallel redundant system giving you 100%
conditioned power at all times. Its unique digital design eliminates the system level single
point of failure inherent in traditional parallel UPS modules, and exponentially increases the
reliability of the overall system.
Hot Sync allows up to four UPS units to cover the same load in parallel and redundant
configuration. No vulnerable master logic is needed in this patented design. It provides
automatic load sharing and module level redundancy with nothing other than the power
connecting the Hot Sync version of UPS modules.
2.5 Basic system configuration
The following basic UPS system configurations are available:
•

being installed. Use the procedures and illustrations in the following chapters to create a logical
plan for installing the system.
3.1 Planning installation
The UPS and accessories are delivered on a specifically designed pallet that is easy to move with
a forklift or a pallet jack. Make sure that the floor surface is solid and suitable for the wheeling
and heavy weight. Keep the UPS always in upright position and do not drop the equipment. Do
not either stack the pallets because of high-energy batteries involved and the heavy weight
Use a forklift or pallet jack to move the packaged cabinet to the installation site, or as close as
possible, before unpacking. Insert the forklift or pallet jack forks between the pallet supports on
the bottom of the unit. Set the pallet on a firm, level surface, allowing a minimum clearance of
3m on each side for removing the cabinet from the pallet.
Note!
If the UPS is not immediately installed the following must be remembered:
• The UPS should be stored in the original packing and shipping carton.
• Do not tilt the UPS cabinet more than 10° from vertical or cabinet may tip over.
• The recommended storing temperature is between +15° … 25°.
• The equipment must always be protected from moisture and weather.
The life of the UPS system is adversely affected if the installation does not meet the following
guidelines:
•
•
•
The system must be installed on a level floor suitable for computer or electronic equipment.
The system must be installed in a temperature and humidity controlled indoor area free of
conductive contaminants.
The UPS cabinet uses forced air cooling to regulate internal component temperature. Air
inlets are in the front of the cabinet and outlets are in the top. You must allow clearance in
front of and above each cabinet for proper air circulation.
The operating environment must meet the weight, clearance, and environmental requirements
in the technical specification.

10.
Connect positive, negative, and ground DC power wiring from battery cabinet to the
battery terminal Block and ground terminals in the UPS cabinet.
Note that the battery cables delivered with the battery cabinets are to be installed next to
the UPS cabinet. Cables with higher current capacity are needed if the external battery
cabinets or racks are installed with a distance from the UPS.
11.
When all wiring is complete and the UPS system is connected to the facility power and
critical load, reinstall safety shield panels removed in previous steps.
12.
Close door and secure with latch. If an external bypass switch shall be used, contact your
dealer first.
The UPS unit is now connected to the mains and to the load but there is no power. Make sure
that the connections are properly made.
Standards SFS 6000-5-52 (2002) and IEC 60364-5-52 (2001-08) “Electrical installations of
buildings” with normal 1.7xNeutral conductor rating for IT loads are used as a sizing guide.
For any other conditions, size the cables according to the local safety regulations regarding
installation environment, appropriate voltage and currents of the UPS.
Fuses are sized according to local safety regulations, appropriate input voltage and the rated
current of the UPS. Therefore, protect the input and bypass cables with gG (gL) fuses or B-C-D
type of circuit breakers against overload and short-circuit.
Contact the manufacturer’s authorised agent or the local office for assistance at fuse and cable
sizing. Refer to the recommended cable and fuse ratings in the below table.

4.2.1 Installing battery ferrite rings
Four ferrite rings are delivered with 40-80 kVA UPS and meant for DC power cables. It is recommended that
all power wires (+ and -) are routed through the four ferrite rings. If the double cable is used, one pair of
positive and negative (+ and -) wires should be routed through two ferrite rings and another pair of positive
and negative (+ and -) wires should be routed though another two ferrite rings. In every situation place the
ferrite rings as close the inside wall of the UPS cabinet as possible.
4.2.2 Installing ferrite clip for battery breaker
The ferrite clips are delivered and meant for control wires between the UPS and the battery breaker. Place
the control wires to the notch of the clip, make a loop at least once and close the ferrite clip. Place the
ferrite clip as close the inside wall of the UPS cabinet as possible.
4.3 Battery cabinets
Power and control wiring for integral line-up and match battery cabinets are supplied with the cabinets.
The battery cabinet may be located either to the left or right of the UPS cabinet. Due to easier service
access the recommended location is to the left of the UPS cabinet. The line up and match battery cabinets
are wired through the side panels of the units.
Mechanical lugs, located at the front of the cabinet, reduce installation time, and removable battery trays
with quick disconnects between trays reduce battery maintenance time. A DC-rated circuit breaker within
each cabinet provides protection and servicing isolation.
The battery cabinets use convection cooling to regulate internal component temperature. Air inlets are in
the front of the cabinet and outlets are in the top. Clearance must be allowed in front of and above each
cabinet for proper air circulation.
• The system must be installed on a level floor suitable for computer or electronic equipment.
• The system must be installed in a temperature and humidity controlled indoor area free of
conductive contaminants.

Maintaining the UPS System
8.1 General
The components inside the UPS cabinet are secured to a sturdy metal frame. All repairable parts
and assemblies are located for easy removal, with very little disassembly. This design allows
authorised service personnel to perform routine maintenance and servicing quickly.
You must schedule periodic performance checks of your UPS system to keep it running
properly. Regular routine checks of operation and system parameters will enable your system to
function efficiently for many trouble-free years.
8.2 Important Safety Instructions
Remember that your UPS system is designed to supply power EVEN WHEN DISCONNECTED
FROM THE UTILITY POWER. The UPS module interiors are unsafe until the DC power source
is disconnected and the electrolytic capacitors are discharged. After disconnecting the utility
power and the DC power, authorised service personnel should wait at least five minutes for
capacitor bleed off before attempting internal access to the UPS module.
Warning!
• Qualified service personnel should perform servicing and maintenance only.
• LETHAL VOLTAGE PRESENT. This unit should not be operated with the cabinet doors
open or protective panels removed. Do not make any assumptions about the electrical
state of any cabinet in the UPS system.
Since each battery string is an energy source in itself, opening the Battery Circuit Breaker
does not de-energise the voltage within the battery string. DO NOT ATTEMPT TO ACCESS
ANY INTERNAL AREA OF THE BATTERY STRING YOURSELF. VOLTAGES ARE ALWAYS
PRESENT IN THE BATTERY STRINGS. If you suspect that a battery string needs service, you
should contact your service representative.
If the string requires service, refer to the battery manufacturer‘s operating manual for
instructions on battery maintenance, or contact your service representative.
Observe these precautions when working on or around batteries:
•
•
•
•
•
•
•
•
Remove watches, rings, or other metal objects.
Use tools with insulated handles.
Wear rubber gloves and boots.
Do not lay tools or metal parts on top of batteries or battery cabinets.
Disconnect the charging source prior to connecting or disconnecting terminals.
Determine if the battery is inadvertently grounded. If it is, remove the source of the ground.
Contact with any part of a grounded battery can result in electrical shock. The likelihood
of such shock will be reduced if such grounds are removed during installation and maintenance.
When replacing batteries, use the same number of sealed, lead-acid batteries.
Proper disposal of batteries is required. Refer to your local codes for disposal requirements.

X2 and X4 input terminals have a five-wire connection (L1, L2, L3, N, and PE). Power cables
with copper conductors should be used to fit the terminals. The wiring shall be done according
to the wiring diagram. The terminals and cable routing is shown it the figure below.
Auxiliary contact information of the system bypass switch enables a safe transfer of the load.
Pay attention that the signal cable of the bypass switch aux. contact is wired correctly to
the UPS modules: the polarity of the signal must be the same for all parallel connected UPS
modules because the signal sensing is done against the ground.
Note!
UPS modules should get a minimum of 10 ms leading closed-contact signal when the
system bypass switch is turned from UPS to BYPASS position.

Recommended cables and fuses for the (4) UPS with SPM wiring diagrams.
Required parallel system wiring length should be in accordance with the following rule, as
referenced to the diagram below, to ensure approximately equal current sharing, when in static
bypass mode:
Total length of 1A + 1B
= Total length of 2A + 2B
= Total length of 3A + 3B
= Total length of 4A + 4B
This rule has a tolerance of approximately +/- 10% for the combined input and output wire
lengths. If installing only two UPS modules, this requirement is no longer required, as each
UPS is capable of supporting the full bypass requirement. However, this would preclude future
expansion.

Note!
The Hot Sync CAN Bridge card has build-in termination resistor enabled by jumper
J7. The default jumper setting without termination resistor is J7: Pin 2-3. Place the the
jumper J7 to correct setting: the first and last UPS modules should have the CAN bus
termination resistor enabled (Jumper J7: Pin 1-3).
In addition to the CAB bus cable a back-up pull-chain cable is needed for bypass operation.
