2 INTRODUCTION
An Uninterruptible Power Supply (UPS) provides the power for critical loads that need a reliable,
continuous, disturbance free supply.
In case the power provided by the Mains Fails, or exceeds the permitted tolerances, the power to supply
the Load is provided by the Battery for the specified time at the rated Load (or longer at a reduced Load)
or until the Mains power returns.
SitePro is a true double conversion VFI (Voltage Frequency Independent) UPS system where the Load is
continuously supplied by the Inverter through the Rectifier.
SitePro can be configured, if chosen, for the SEM mode (Super Eco Mode) permitting maximum energy
saving.
If the Inverter is not able to supply the required Output Voltage, or when overload or short-circuit on the
output occur, the Load is instantly transferred to the Mains via the Automatic Bypass.
The UPS automatically returns to normal mode when the failure condition is restored.
Key features:
More Critical equipment supported
Rated at 0.9 Power Factor, SitePro delivers more real power than other UPS in the market.
With today’s trend toward power factor corrected loads, SitePro can support more total Load than any
other UPS available, allowing you to support a greater number of today’s enterprise computing Power
Factor Corrected (PFC) equipment.
No single point of failure
Redundant Parallel Architecture (RPA) is an exclusive GE technology.
With RPA, SitePro UPS are controlled in a true peer-to-peer configuration where all critical elements and
functions (including Bypass) are redundant.
SitePro is designed to be the most reliable power protection system available on the market today.
High Efficiency
Using IGBT technology and Space Vector Modulation (SVM) strategy, SitePro offers low output voltage
distortion and provides efficiencies up to 93%.
Fully digital
Digital Signal Processor (DSP), Flash memory and SVM strategy are the technology corner stones of a
new age of power quality and power reliability.
Extremely flexible
Tailor made power protection to meet your individual installation requirements; SitePro offers various
options like input harmonic filters and our comprehensive JUMP software suite for mission control and
data protection to cover all your application needs.

3 DESCRIPTION
3.1 BLOCK DIAGRAM AND MAIN ELEMENTS
Fig. 3.1-1 Block diagram
The SitePro system can be divided into the following main elements:
Control system
SitePro is designed with microprocessor-controlled signal processing circuits.
The interface between the operator and the unit is provided by the monitoring system on the front
panel.
This monitoring system consists of an active mimic diagram, a keyboard and a backlit display.
Rectifier
The standard rectifier consists of a 6-pulse SCR-bridge, which converts the 3-phase mains voltage into a
controlled and regulated DC-voltage.
This regulated DC-voltage is used to supply power to the inverter, and to provide charging power to the
battery.
Inverter
The inverter converts the DC voltage into a three-phase AC-voltage with constant amplitude and
frequency, which is completely independent and isolated from the AC-input voltage.
Automatic bypass
The automatic bypass consists of a static semiconductor-switch (SSM: Static Switch Module), used to
provide an uninterrupted transfer of the load from inverter to mains.
Back-feed Protection
All SitePro UPS's are equipped with an automatic system for the protection against voltage back feeding
towards Utility, through the bypass (Applied Standard IEC 62040-1).
This protection works automatically by opening contactor K6 (in series with the thyristors of the static
switch) and eventually K7, and acts in case of internal defects of the system, or due to wrong
manipulations on the maintenance bypass Q2.
Manual bypass
The manual bypass consists of a pair of manual switches Q1 and Q2, which removes the UPS from the
load for maintenance, while still supplying the load with power directly from the mains.
Battery
The battery supplies the DC power to the inverter when the mains is out of accepted tolerances.

OPM_SPE_XXX_60K_60K_7GB_V010.doc Operatine Manual SitePro 60 kVA
3.2 OPERATION MODES
3.2.1 Normal operation mode VFI (Voltage Frequency Independent)
Under normal conditions the load is
permanently powered by the inverter with
constant amplitude and frequency.
The rectifier, powered by the mains, supplies
the inverter and the battery-charger keeps the
battery fully charged.
The inverter converts the DC voltage in a new
AC sine wave voltage with constant amplitude
and frequency independently from the input
mains power.
Fig. 3.2.1-1 Block diagram normal operation mode
3.2.2 SEM mode operation (Super Eco Mode)
When the SEM mode is selected, and the
mains power is available, the Load is normally
powered through the Automatic Bypass.
When the mains voltage is detected out of the
prescribed tolerances, the Load is
automatically transferred to the Inverter.
When the Mains recovers, the Load returns to
the Automatic Bypass after a variable time
defined by the control unit.
Fig. 3.2.2-1 Energy flow in SEM mode operation
The SEM mode can be configured directly by the user for higher efficiency, considering the Mains
reliability and criticality of the Load.
The selection between the two operation modes “VFI mode and SEM mode”, or switching between
operation modes at required time, can be done through the UPS control panel (see Section 7.5-7).
In case of parallel system
SEM mode (Super Eco Mode) cannot be enabled for RPA Parallel System.
Attention: A single unit equipped with a RPA - Parallel board, must be considered as parallel, thus
disabling SEM.

OPM_SPE_XXX_60K_60K_7GB_V010.doc Operatine Manual SitePro 60 kVA
3.2.3 Mains failure operation
When the Mains is no longer within acceptable tolerances,
the Battery will provide the DC power to the Inverter.
The Inverter will maintain continuous AC power to the
Load until the Battery Voltage reaches the lower limit of
the Inverter operation capability.
During the discharge, the LCD screen displays the
estimated time the Battery can support the critical load.
Prior to complete Battery discharge, the "stop operation"
alarm (shutdown imminent) warns the operator that the
Battery is almost discharged and the UPS is about to shut
down.
Fig. 3.2.3-1 Block diagram Mains Failure operation
In case of parallel operation
With a parallel system for power capacity (see Section 3.3)
• With the Bypass Mains power available, a “Battery low” warning on any unit will cause the Load
to be transferred to Mains (after a selectable time delay).
• With Bypass Mains power not available, a “Battery low” warning on any unit will start the “stop
operation” timer (adjustable).
The Load will shut down at the end of the “stop operation” time period.
With a parallel system for redundancy (see Section 3.3)
• When a Battery low warning occurs on a unit not necessary to support the present load, this unit
will shut down after a timeout period (selectable).
The Load is shared between the other units.
• As the warning occurs on one unit necessary to support the present load, the system starts the
"stop operation" timeout (selectable).
The Load will shut down at the end of the “stop operation” time period.
3.2.4 Mains recovery operation
As soon as the AC input power recovers, the Rectifier will
start automatically, supplying DC power to the Inverter
and recharging the Battery.
If the Inverter was previously shut down due to low
Battery, the Load will be initially powered by Mains
through the Automatic Bypass.
When the Battery is sufficiently recharged to ensure a
minimum time of operation with the present load, the
Inverter will start automatically and the Load will be
transferred back to the Inverter.
Fig. 3.2.4-1 Block diagram Mains recovery operation
In case of parallel operation
When the AC input power recovers, the Rectifiers will start up sequentially, according to their
number in the parallel system. This minimizes the initial inrush current.
The Inverters will start up automatically, but only when the Battery has been sufficiently recharged
for a minimum runtime with the present load.
When enough Inverters to supply the Load have been restarted, the Load will be transferred from the
Automatic Bypass back to the Inverter output.

OPM_SPE_XXX_60K_60K_7GB_V010.doc Operatine Manual SitePro 60 kVA
3.2.5 Automatic Bypass
In normal operation, the Load is supplied by the
Inverter.
When the control system detects a fault in the
Inverter, an overload condition or a short-circuit
condition, the Automatic Bypass will transfer the
critical Load to the Mains without interruption.
When the Inverter recovers, or the overload or
short-circuit condition is corrected, the Load will
be automatically transferred back to the
Inverter.
If the UPS is unable to return to normal mode
following an automatic transfer to Bypass mode,
an alarm condition will be initiated.
A Manual Bypass (operator initiated) will not be
considered as an alarm condition.
Fig. 3.2.5-1 Block diagram Automatic Bypass
In case of parallel operation
Each unit has its own internal Bypass.
These units are continuously exchanging information, enabling all of the internal Bypass circuits in a
parallel system to operate simultaneously.
If the Inverter of a unit fails, its Bypass circuit remains available to the parallel system.
It is excluded only if the unit is separated from the common bus by opening its output switch Q1.
3.2.6 Manual Bypass
The Manual Bypass circuit consists of manual
switches Q1 and Q2, which permits transfer of
the Load directly to the unconditioned AC power
without interruption, leaving the UPS available
for maintenance.

3.3 PARALLEL SYSTEM OPERATION
3.3.1 Introduction to the parallel system
Two or more equal power units can be paralleled to increase the output power (paralleling for
capacity) or to improve the overall reliability of an UPS system (paralleling for redundancy).
The outputs of parallel units are connected to a common power bus, and in normal operation the units
connected on the parallel bus share the Load equally.
The modular concept of SG Series allows parallel operation of up to 8 units, without using paralleling
switchgear, external bypass circuits or common control circuitry (see Fig. 3.3.1-1).
Parallel units for power capacity
Several units can be paralleled in order to achieve output power greater than the maximum power of a
single unit.
The maximum total power shared between the paralleled units is equal to the total installed nominal
power.
In the event of a failure of one unit, the power supplied by the UPS system becomes insufficient and the
Load will be transferred to the Mains Bypass source.
Parallel units for redundancy
The nominal power rating of the n
out of n+1 redundant paralleled modules must be equal to or higher
than the required Load power.
The Load will be equally shared by the n+1
units connected on the output bus.
Should one of the n+1
paralleled units trip Off-line, the remaining (n) modules will supply the load,
maintaining conditioned power to the critical load.
From this results higher reliability and security for the Load plus a higher MTBF (Mean Time Between
Failures).

3.3.2 Features of RPA parallel system
The SitePro parallel system is designed to provide a complete Redundant Parallel Architecture, and is
free from common equipment.
Not only the Inverters but also the Bypass functions are redundant.
When one UPS needs maintenance or service, the Load is powered by the other units.
The redundant communication bus to which all units are connected keeps each unit informed about the
status of all the other units.
The control panel located on each unit allows controlling and monitoring the status of this unit.
3.3.3 System control
A high-speed redundant, serial communication bus guarantees the exchange of data and thus the
communication between the CPU's of each unit.
Each module controls is own function and operational status and communicates with all other modules,
in order to act or react if necessary, adapting to the new conditions.
3.3.4 Synchronization
All units are identical, but one unit is arbitrarily selected as the reference and all the other units
synchronize to this unit, which in turn synchronizes to the Mains Bypass voltage, as long as the latter is
within tolerances.
In case of reference failure, another unit in the parallel system is automatically chosen to take over the
reference role.
The Bypass Input for all the units of the parallel system must be supplied from the same AC source (no
phase shift allowed between them).
3.3.5 Load sharing
On each unit of the parallel system, Inverter Output Voltage and Current are measured and applied to a
Load sharing bus.
An eventual difference between the units is therefore automatically equalized.
NOTE !
It is strongly recommended that no transformers, automatic circuit breakers or
fuses should be installed between the units output and the Load common bus bars.
However, it is recommended that a disconnection or isolation switch is installed in
order to totally isolate a unit if needed.

3.4 RECTIFIERS PARALLELED ON THE SAME BATTERY
NOTE !
A parallel system with a Common Battery for two or more UPS, requires a
particular installation and adequate setting of some parameters, (accessible
only through password), and can therefore only be done by a qualified GE
engineer.
Usually each UPS Unit runs with its own Battery.
In case of parallel units running with a Common Battery (max. 4 UPS - see Fig. 3.4-1), the sharing circuit
between the individual UPS is integrated in the communication bus of the system in order to assure an
equal sharing of the Rectifiers output currents.

Pay attention to the following recommendations:
• The units delivered for this functioning mode needs a special parameters setting, so they must be
prepared in advance before the installation.
• The installation must be performed only with the UPS system must be completely shut down.
• The AC rectifiers input power (5) must be the same, with the right phase rotation for each unit.
• Each rectifier must be set for the same floating DC voltage and the same battery current limitation.
• It is mandatory to install the fuses / MCB (7) on each line connecting the rectifiers to the common
battery for maintenance / safety reasons (for fuses rating see Section 4.7.2).
• In case one must be powered down for maintenance, switch-OFF the concerned unit before open
the DC fuses/MCB on the battery line (7).
• It is recommended to connect an external NO free contact “battery fuses” to the UPS and to enable
the function by setting the parameter (see Section 9.1).
• If an emergency generator set supply the UPS, and the free contact “Generator ON” is connected to
the Customer interface, connect a separate NO free contact on each parallel unit.
• The parameters enabling the battery test, both manual and automatic, must be set in the same
mode on all the units having the rectifiers on common battery.
• Do not connect the temperature sensor (standard delivery on SitePro 10 – 60 kVA) for automatic
battery floating voltage compensation.
• Do not enable the function Boost charge (parameter 87).

4.2 DELIVERY
When delivered, inspect the package integrity and the physical condition of the cabinets carefully.
In case of any damage sustained during transport, immediately inform the carrier and contact your
local Service Centre.
A detailed report of the damage is necessary for any insurance claim.
NOTE !
A damaged UPS must never be installed or connected to mains or battery!
4.3 STORAGE
4.3.1 Storage of the UPS
The UPS is carefully packed for transport and storage so that it is in perfect condition when installed.
Never leave a UPS outside the building and don’t store other packages on the top of the UPS.
We recommend to store the UPS in its original package in a dry, dust-free room, away from chemical
substances, and with a temperature range not exceeding -25°C (-13°F) to 55°C (131°F).
Some important functions of the UPS, such as the customized functions, are defined by parameters
stored in a RAM memory.
A small backup Battery located on the Control Unit board supplies the RAM.
If the storage time of the UPS exceeds 1 year, these functions should be verified by an authorized
Service Centre before putting the UPS into operation.
4.3.2 Storage of Battery
When the delivery includes a maintenance free Battery, keep in mind that they are subject to selfdischarge and therefore you must recharge the Battery.
The storage time without Battery recharge depends on the temperature of the storage site.
The optimal temperature for Battery storage is 20°C (68°F) to 25°C (77°F).
Recharge stored maintenance free Battery every:
6 months when the storage temperature is 20°C (68°F)
3 months when the storage temperature is 30°C (86°F)
2 months when the storage temperature is 35°C (95°F)

4.4 PLACE OF INSTALLATION
4.4.1 UPS location
WARNING !
UPS installation and connection must be performed by QUALIFIED SERVICE
PERSONNEL only.
If optional cabinets and accessories are included with the UPS, please refer to those
accompanying manuals for installation and operating instructions.
It is important to have a clean, dust-free place provided with proper ventilation or air-conditioning to
keep the ambient within the specified operating range.
The recommended air inlet temperature is from 20°C (68°F) to 25°C (77°F) (max. 35°C / 95°F).
Refer to Section 4.5.
Check for sufficient floor load capacity before installing the UPS and the battery.
Refer to Section 4.1.1.
For battery installation follow the local codes and the recommendation of the battery supplier.
NOTE !
Temperature is very important for valve-regulated batteries (maintenance free).
Operation at temperatures higher than 77°F (25°C) will reduce battery life.

Fig. 4.4.1-1 SitePro 60 kVA disposition
The UPS cabinet can be positioned against the wall
but, in order to improve the ventilation and to make
easier the maintenance operations for UPS and
battery, we recommend a minimum distance of 200
mm (8”) from the wall.
The right side of the UPS cabinet must be
accessible for maintenance operation.
Clearance around the front should be sufficient to
enable free passage of personnel with the doors
fully opened.
Recommended minimum clearance between ceiling
and top of the UPS should be 400 mm (16”) for
proper cooling air exhaust.
In case of optional cabinets (THD filters,
transformers, battery), the additional cabinets must
be placed beside the left end of the UPS cabinet
face.
See Chapter 8. – OPTIONS.

OPM_SPE_XXX_60K_60K_7GB_V010.doc Operatine Manual SitePro 60 kVA
The UPS cabinet is free standing and normally does not require bolting to the floor.
In any case the cabinet basement is suitable to be floor fixed, when requested by local standards.
In case of parallel system, try to place the UPS
modules in sequence of their numbers (marked
on the packing).
If the units are positioned “side by side”, the side
panels must be mounted on all units.
Remove the side air inlet grids on the
intermediate units to run the control bus cable
connections.
Fig. 4.4.1-3 RPA system disposition
4.4.2 Battery location
Batteries require a well-ventilated room with controlled temperature to obtain reliable operation.
The Battery can be install immediately adjacent to the UPS (left or right side) or remotely from the UPS.
If the Battery is installed remotely from the UPS, a wall mounted DC disconnect device must be installed
within line-of-site to both the UPS and the Battery.
The optimal room temperature for the Battery is 20°C (68°F) to 25°C (77°F).
The life of valve-regulated batteries will be reduced by 50% for each additional 10°C (18°F) that the
Battery ambient temperature is above 25°C (77°F).
The Battery System associated with larger UPS is usually either rack mounted or installed in multiple
Battery Cabinets.
Installation and assembly must be made according to the local standards and Battery System
manufacturer‘s recommendations.
The Battery Circuit Breaker or Battery Fuse Box must be mounted as near as possible to the Battery.
WARNING !
Battery installation and connection must be performed by QUALIFIED PERSONNEL
ONLY.
Read all safety instructions before proceeding with the installation (see Section 1).

4.5 VENTILATION AND COOLING
Fig. 4.5-1 Installation on plain floor Fig. 4.5-2 Installation on raised floor
The heat produced by the UPS is transferred to the environment by its ventilation.
Cooling air enters the cabinets through the air inlet (grids) located at the bottom and exhausted through
the outlet on the roof.
A suitable ventilation or cooling system must be installed to extract the heat from the UPS room.
NOTE !
Insufficient distances on both sides of the UPS could increase the temperature
inside the UPS.
Do not put any object on the top of the cabinet: it might obstruct the air flow.
If the UPS is placed on a raised floor, the airflow for UPS cooling should enter from underneath the UPS,
through the appropriate aperture on the raised floor.
Air filtration systems could be required when the UPS operates in a dirty environment.
Contact your Dealer or the nearest Service Centre for appropriate solutions.
In order to prevent overheating of the UPS, the available air intake flow rate must exceed the total air
exhaust flow rate requirement of the UPS system.
The below table indicates the heat dissipation at full load at PF = 0.8 lag. and charged battery, up to
1000 m (3280 ft) altitude, for cooling air 25°C (77°F) to 30°C (86°F).

4.6 UNPACKING
The UPS and battery cabinets may be shipped packaged in carton boxes or in wooden crates (if
requested).
Move the cabinets as close as possible to the final location before removing from the pallet.
If delivered in a wooden crate, remove the cabinet from the pallet with care, because of the heavy
weight of the equipment.
NOTE !
Be aware of the heavy weight of the UPS, pay attention when moving the UPS
cabinet.
Ensure that the cabinet is not damaged when moving by forklift.
Included in the delivery packing are the air inlet grids, which must be mounted on the 4 sides at the
bottom of the cabinet with the screws included in the accessory bag.
If necessary, the terminal with the sensor must be mounted in the battery enclosure or cabinet (not in
contact with metallic parts) and the J3 plug must be connected to ”P1 - Power Interface” (see Section
4.8.3).
When the sensor is disconnected, the floating voltage is calibrated for temperature = 20°C.
If the battery cabinet is not mounted side by side the UPS, the cable connecting the temperature
sensor to the UPS should be run in a protective trunk or conduit.
NOTE !
If the battery distance from the UPS is >5 m, we suggest do not use this circuit
and the correct loading voltage must be installed manually according to the
annual average temperature at which the battery will be working (request
instructions to Service Centre or battery supplier).
For parallel systems, the delivery also includes the bus control cables for interconnecting the UPS modules.
Packing material recycling
GE, in compliance with environment protection, use only environmentally
friendly material.
UPS packing materials must be recycled in compliance with all applicable
regulations.

4.7 ELECTRICAL WIRING
WARNING !
UPS installation and connection must be performed by QUALIFIED SERVICE PERSONNEL
only.
Refer to the “Safety prescriptions - Installation” described on Section 1.
4.7.1 Mains input connection
WARNING !
Ensure that the AC and DC external isolators are OFF and locked out to prevent their inadvertent
operation.
Do not apply power to the equipment prior to the commissioning by a qualified service engineer.
Before any other input connection, connect and check the earthing wire.
The mains input power connection can be common or separate for bypass supply and rectifier input,
depending on the electrical system provided by the customer.
Common input Rectifier & Bypass
The same power source is to be used for both bypass supply and rectifier input (input F3).
Bear in mind that when the mains fuses are opened there is a supply failure to the rectifier as well as t
o
the bypass and manual bypass switch.
In this case, the interconnection links BR1, BR2 and BR3 on the input terminals or bus
bars MUST REMAIN CONNECTED.
Separate input Rectifier & Bypass (recommended)
The bypass and rectifier use different power sources (F1 and F2 inputs).
In this case, when the rectifier-input fuses are opened, the automatic bypass and the manual bypass
are supplied by the other connection.
In this case, REMOVE the interconnection links BR1, BR2 and BR3 on the input terminals
or bus bars. See Fig. 4.8.3-2 and Fig. 4.8.4-2.

4.7.2 Input/output overcurrent protection and wire sizing
The cabling of the UPS system has to be sized according to the UPS power rating.
Exceptions are only allowed to suit local prescriptions.
Sizing of circuit breakers, fuses and cables for input mains, output load and battery must meet the
requirements of local and national electrical codes.
Before connecting the UPS, verify that the mains voltage and frequency, the output load voltage and
frequency and battery data (cells number, floating voltage, autonomy) are according to the required
data.
Protection of the UPS mains input, must be exclusively with 3 pole breakers.
The UPS needs the connection of the Neutral to the input, to guarantee the function in TN mode.
Caution when using four-pole circuit breakers as protection to the load of the UPS.
A potential problem exists for situations with non-linear loads: the neutral current could be greater
than the phase currents.
Avoid to run the input cables in parallel with the output cables to prevent them from noise induction.
The three-phase Mains power supply must be symmetrical with respect to earth, due to the existence of
voltage surge protection devices inside the UPS.
NOTE !
If you use ELCB breakers to protect the input connections, consider the high leakage
current towards the earth generated by the noise suppression capacitors.
If these ELCB breakers are strictly necessary, we suggest to use the largest type
suitable for non-linear current and for delayed operation.
To ensure the circuit selectivity in case of short- circuit in the load equipment, special care must be
taken in choosing the fuse or circuit breaker ratings installed in the output distribution circuits.
Due to the relatively low short-circuit capability of the UPS inverter, a short-circuit in the load will cause
an immediate transfer to mains.
The largest fuse in the output distribution should be at least 1.6 time smaller than the fuses supplying
the bypass line.
If circuit selectivity is required while the load is fed from the inverter (bypass mains not available), the
largest fuse or circuit breaker should be rated at no more than 20% of the UPS output current rating.

4.8.2 Choice of AC input for the power supply
The control and regulation circuits are supplied by two separate power supplies:
one powered from AC mains input voltage and another powered by DC battery voltage.
The AC power supply can be powered either by bypass mains input (standard version, suitable in most
cases) or rectifier mains input.
The input of the AC Power Supply AC must be supplied from the mains input rectifier:
• In case the UPS is used as frequency converter (mains input bypass terminals not powered);
• With separate AC inputs, following a complete battery discharge, the UPS system must be restarted
only having the rectifier-input terminals powered.

4.8.3 Functioning as frequency converter
When the UPS is delivered for different output frequency with respect to the input frequency, the
automatic bypass and manual bypass functions are disabled, therefore the load cannot be transferred
to mains in case of overload, short-circuit, or inverter failure.
In cases where the UPS needs to be powered down for maintenance purposes, the critical load must
also be powered down during this time.
When the set-up parameters of the UPS are set for frequency converter, the SEM mode operation is
automatically disabled.
Notices for installation:
• In order to avoid improper operation, only the rectifier input should be powered (L1-1, L2-1 and L3-
1), therefore BR1, BR2 and BR3, on AC input bars must be removed (see Section 4.8.1).
• Special care must be taken in choosing the fuse ratings installed in the output distribution (max.
20% of the UPS rated current).
Avoid high inrush current due to transformer magnetisation or motor starting.
Notices for start-up operation:
• Since the AC-Power supply is fed from the input mains rectifier (see Section 4.8.2), the control panel
will be powered ON only after closing the input switch Q4.
• The lamp B1 - BYPASS PHASE OK on ”P1 - Power Interface” (see Section 4.8.2) for clockwise phase
rotation check will stay OFF.
• After closing the output switch Q1 the output will not yet be supplied and the LCD screen displays
“load off”.
The output bus will be supplied only when the inverter is running and the LCD screen displays “LOAD
ON INVERTER".
• If the UPS has been previously shut down, reset of “load off” must be done by pushing
simultaneously for few seconds the “load off” push-button and the “I” key (inverter ON).
Notices for shut-down operation:
• The inverter can be switched OFF pushing the key "O" (inverter OFF) only after having pushed the
push-button “load off” (all equipment normally powered by UPS are shut down).
Then follow the normal shut down procedure indicated to Section 8.2.1.
WARNING!
Do not allow unattended operation of the inverter with the output switch Q1 open.
This is an abnormal operating mode and some important protective functions are
disabled!
Do not allow the inverter to continue running after the “load off” button is
activated!
NOTE !
At site only a qualified service engineer may change a unit, initially delivered as a
frequency converter, into a normally operating “standard” UPS.

4.9 RPA PARALLEL SYSTEM CONNECTION
WARNING !
This operation must be performed by trained personnel before the initial start-up
(ensure that the UPS installation is completely powered down).
4.9.1 Power wiring of parallel units
To guarantee good Load sharing between the units of a parallel system, we recommend that the cable
length from the input distribution board (5) to the output distribution board (10) is equal for each unit
(a+b = c+d = e+f = g+h = i+l = m+n = o+p = q+r).
Tolerance: +/-10%.
The AC input power of the Bypass must be the same for all units of the parallel system - no phase shift
allowed between units.
NOTE !
It is strongly recommended that no transformers, automatic circuit breakers or fuses
should be inserted between the unit’s output and the Load common bus bars.
However, it is recommended that a disconnection or isolation switch is installed in
order to totally isolate a unit if needed.
Verify that power wiring and control wiring run in separate conduits or cable trays.
The power wiring requires two separate conduits: one for input and one for output cables.

4.9.2 Parallel control bus connection
In cases of parallel operation, the communication between the units take place through the control bus
cables:
Each parallel unit is equipped with an additional board “P13 – RPA Board“ where the connectors J52 (A)
and J62 (B) are located.
A short control cable provided with a ferrite ring core link the parallel board “P13 – RPA Board” with the
parallel bus socket on which must be connected the control bus cables A and B.
All the parallel units are connected to the same control bus.
This connection allows:
• The micro-processors of each unit to communicate with each other;
• The oscillators of each unit to be locked together;
• The regulation loops to compare the output current of each unit in order to equally share the load
current.
For increased reliability, this connection is made with redundant cables.
In this way, communication is maintained between units in case one of the control cables should fail or
be accidentally damaged or disconnected.
The standard length of the control bus cable between two parallel unit is 12 m / 40 ft.
Maximal overall length of bus connection, between the first and the last unit, should not be longer than
84 m / 276 ft.
Verify that control wiring is run in individual separate steel conduit.
NOTE !
Under no circumstance should the control bus cable connecting JA (1/2/3/4/5/6/7) and
JB (1/2/3/4/5/6/7) be connected or disconnected after the system has been powered On.

Control bus cables routing
Place and fix the cables JA-1/2/3/4/5/6/7 and JB-1/2/3/4/5/6/7 inside the UPS cabinets in the
position illustrated in the drawing.
NOTE !
Pay attention when cabling and routing the bus cables JA and JB inside the UPS
cabinet.
In case one unit should be removed from the parallel system, the bus cables JA and
JB must be removed from the cabinet without disconnecting them from the metal
plate where the sockets JA and JB are located.
For reliability reasons the cables JA-1/2/3/4/5/6/7 and JB-1/2/3/4/5/6/7 connecting the units should
be run in separated protected conduits (as indicated in fig. 4.11-4) separated from the power cables.
It is important that the cable JA must be the same length as cable JB.
WARNING !
Connection and commissioning of an additional UPS to an existing parallel system,
must be performed by a service engineer from of your Service Centre.

Type 3: Boolean parameters used to simulate command buttons.
The Boolean parameters have a range of Yes/No.
Only the user performs the modification of the value.
These “Type 3” parameters are used to initiate an action. There are two possibilities:
A 1 – The user wants the UPS to start the action => the user sets the parameter to “Yes”.
2 – The UPS finishes the action => the UPS sets the parameter to “No”.
B 1 – The user wants the UPS to start the action => the user sets the parameter to “Yes”.
2 – The user wants to abort the action => the user sets the parameter to “No”.
The actions that can be performed using such software buttons are:
• Print the metering information.
• Print the last 256 events.
• Print the values of the parameters.
• Print all the information obtainable from the UPS.
Returning from the Edit mode
Normally the ok button is used to return from the Edit mode.
Then the UPS will perform some validity tests on the new value.
If these tests are successful then the new value is saved and used.
If these tests fail the Edit mode is not exited.
NOTE !
The validity tests performed by the UPS are not exhaustive.
You should not rely exclusively on these tests.
Care should be taken when modifying the values of the parameters.
For all parameters except the LCD Contrast parameter the new value is saved and used after the ok
button was pressed.
In the case of the LCD Contrast parameter the new value is used immediately in order to obtain a better
visual feedback.

Modem enabled You can enable/disable with Y/N the remote control through modem calls by
using this parameter.
Init This parameter presents the modem initialisation string.
It can be 39 characters long.
When editing this parameter the UPS considers that a blank character terminates
the string.
If no blank character is found then all 39 characters are used.
Alarm This Y/N parameter controls the automatic events signalling through modem.
If this parameter is set to Yes the UPS itself will call the remote location when a
new event occurs.
Delay This parameter controls the delay between the occurrence of a new event and the
modem dialing.
It is useful because since the events typically do not occur isolated but in certain
sequences, you can eliminate the need for multiple dial-outs for such a sequence
of events.

SEM MODE:
This parameter (values Y / N) enables or disables the operation in SEM mode (Intelligent Energy
Management).
If the value is Y and the current time is in the interval for the current day, the SEM mode is active.
The activation / deactivation of SEM mode is indicated each time in the event list.
In order to check the inverter function, at least 1 minute of VFI mode must be programmed during the
week (the Y / N parameter is automatically disabled if this condition is not satisfied).
In case this minimum time in VFI mode is not respected, the SEM mode will be disabled.
If the value is N, the UPS is normally operating in VFI / double conversion mode at all times.
d1 ÷ d7: Enabling time in function of weekdays.
For the weekdays from d1 to d7 (Saturday to Friday) the edit mode (edit day) allows to define time
intervals when the UPS is operating in SEM mode.
The hour is given in 24-hour format.
These intervals are defined by:
SEM START: the hour of the day after which the SEM mode is enabled.
The SEM mode is enabled until the following SEM STOP time is reached (the SEM STOP
time of the same day if this is later than the SEM START time, the SEM STOP time of
the following day otherwise).
SEM STOP: the hour of the day before which the SEM mode is enabled.
The SEM mode is enabled starting from the preceding SEM START time (the SEM START time of the same
day if this is earlier than the SEM STOP time, the SEM START time of the previous day otherwise).
Identical times for SEM START and SEM STOP maintain the existing mode only in case the previous
command was SEM START and the following command will be SEM STOP.
HOURS SELECTED:
The number of SEM mode hours per weekday (from d1 - Saturday to d7 - Friday) is displayed in the
operation mode parameter window (ceiling value).
To better understand the SEM programming modes, some typical examples are shown:
Example 1:
For continuous SEM mode set the SEM START times to 00:00 and the SEM STOP times to 23:59 for all
weekdays, but almost 1 day must have 1 minute of VFI programmation: i.e d2 - Sunday 00:00 to 23:58).
Weekday d1 - Saturday d2 - Sunday d3 - Monday d4 - Tuesday d5 - Wednesday d6 - Thursday d7 - Friday
SEM START 00:00 00:00 00:00 00:00 00:00 00:00 00:00
SEM STOP 23:59 23:58 23:59 23:59 23:59 23:59 23:59

Example 2:
SEM STOP before SEM START.
SEM START 18:00, SEM STOP 06:00 for weekday d4 - Tuesday.
Means that on d4 - Tuesday the SEM mode is active between 00:00 and 06:00 and between 18:00 and
23:59.

SEM STOP 23:59 23:59 23:59 06:00 23:59 23:59 23:59
Example 3:
SEM mode during the night and week-end.
If the SEM mode must be enabled all nights (d3 - Monday ÷ d7 - Friday) between 18:00 in the evening
and 06:00 of the following morning and during all Saturday (d1) and Sunday (d2), the corresponding
parameters are:
Weekday

SEM START 00:00 00:00 18:00 18:00 18:00 18:00 18:00
SEM STOP 23:59 23:59 06:00 06:00 06:00 06:00 06:00
Example 4:
If the SEM mode must be enabled on Monday (d3) and Tuesday (d4) between 18:00 in the evening and
06:00 of the following morning, on Friday (d7) between 12:00 and 13:00, during all Saturday (d1) and on
Sunday (d2) until 20:00, the corresponding parameters are.
Weekday d1 - Saturday d2 - Sunday d3 - Monday d4 - Tuesday d5 - Wednesday d6 - Thursday d7 - Friday
SEM START 00:00 00:00 18:00 18:00 00:00 00:00 12:00

In dark colour are displayed the times with SEM mode operation.
The arrows indicate the conditions given by the SEM START and SEM STOP times introduced with the
parameters.
Note that on day d6 - Thursday the interval has length 0 (zero), therefore the SEM mode is not enabled
on this day.

The SEM mode is active from 18:00 of weekday d3 - Monday until 06:00 of weekday d4 - Tuesday (as
indicated by the SEM STOP time of weekday d4 - Tuesday).
The SEM STOP time of weekday d3 - Monday has no effect as it is followed by the SEM STOP time of
weekday d4 - Tuesday.
It can be, without change of meaning, any time between 18:00 and 23:59.
Similarly, the SEM mode is active from 18:00 of weekday d4 - Tuesday until 06:00 of weekday d5 -
Wednesday.
The SEM START time of weekday d5 - Wednesday has no effect as it is preceded by the SEM START time
of weekday d4 - Tuesday.
It can be, without change of meaning, any time between 00:00 and 06:00.
NOTE !
To avoid undesired SEM mode operation, verify:
• Date and Time (first page of parameter).
• SEM mode screen how many hours of SEM mode operation have been selected
for each day of the week.
NOTE !
The SEM mode will become active only if the load is supplied from the inverter.

Changing the language
Changing the language from Chinese to English and vice versa is possible in any moment by pressing
simultaneously the metering and parameters keys.
Another possibility is to change the language from the PARAMETERS menu when the language set up
screen is displayed.
The procedure is like for the standard 4 x 20 LCD.
Metering
The screens are displaying the same information as per the standard LCD.
The information is split in more parts than on the standard LCD.
For scrolling the screens the +, - and metering keys can be used.
Alarms
The alarms/events are described only using the numeric codes.
For alarms/events meaning please refers to the alarms codes list (see Section 7.7.1).

7.7 EVENTS (ALARMS AND MESSAGES)
Each of the following listed events can be displayed on the LCD screen or on PC where the “PowerJump
Manager” or “PowerJump DataShield” is installed.
Alarms and Messages are differently specified because the alarms are indicating an abnormal
functioning of the UPS (which are additionally signalled with the LED alarm and acoustically with the
buzzer), while the messages indicate the various states of operation of the UPS (stored in the events list,
but not activating the LED alarm and the buzzer).
When in the alarms mode, the LCD screen displays a time ordered sequence of screens corresponding
to the last 256 alarms and messages, each screen indicating:

8 OPERATION
This symbol refers to the operations of a parallel system.
These steps are not applicable for single units.
8.1 START-UP PROCEDURES
Verify that the input/output connections have been performed by qualified personnel before connecting
mains input voltage and verify that the equipment is correctly grounded.
Only open the front door, do not remove any panels.
Now you can initiate the start-up procedure of the UPS system.
There is no need for any specific knowledge if you carefully follow the step by step instructions given
here, but we recommend that at least the initial procedure should be performed by trained personnel
only.
Check after every step for correct reaction of the UPS, eventually measuring voltages and currents
for confirmation, before you proceed to the next step.
If you encounter any problems following the procedures contained in this section, you should contact
the Service dept of the distributor from whom the equipment was purchased.
There are different start-up procedures, as described on the following pages, depending on the
configuration and the initial state of the UPS system:
• Initial Start-up of UPS single and parallel system.
This procedure describes how to switch on a single UPS or a complete UPS parallel system.
Initial start-up following the installation means that the load is not being initially supplied and the
system is still completely powered OFF.
• Start-up single and parallel system following maintenance shut down.
In case of previous maintenance shut down procedure, the load is still powered by the
maintenance switch(es) Q2.
This procedure describes how to transfer the load back on to the UPS.
• Start-up an additional unit in a redundant parallel system.
The load is fully supplied by the other units connected to the parallel bus.
The unit on which we are operating will be connected on the parallel bus bar sharing the load with
each other’s.
WARNING!
Do not allow unattended operation of the inverter with the output switch Q1 open.
This is an abnormal operating mode and some important protective functions are
disabled!
Do not allow the inverter to continue running after the “load off” button is
activated!

9.1.6 Gen Set Signalling (GEN ON)
If an emergency generator set supplies the UPS in case of Mains Failure and the generator is
considerably unstable in frequency, it should be suitable to install the signal “Generator ON” on X1 / 11,
22 or J2 / 11, 24).
See Fig. 9.1-1 / X1 and J2
Since the Parameter for of the reading of the Generator function is password protected, call the nearest
Service Centre for it's activation.
When this contact closes, it changes certain (programmable) functions such as:
• Enabling or disabling of synchronization and consequently the Load transfer to generator.
• Reduction or elimination or delay of Battery recharging during the generator operation.
In a parallel system a separate NO (Normally Open) contact must be connected to
each individual unit.
9.1.7 AUX external Maintenance Bypass
If the UPS system is equipped with an external Maintenance Bypass Switch, it is possible to connect a
NO (Normally Open) voltage-free aux. contact from the External Bypass Switch to the programmable
input X1 / 10, 21 or J2 / 10, 23, making the UPS operate as if the internal switch Q2 has closed.
This function can be activated by changing a dedicated parameter (password required).
When this NO (Normally Open) contact closes, the output Inverter Contactor K7 it is automatically
opened and the Load transfer back to Inverter will be inhibited.
In a parallel system, the input on the customer interface of each unit must be
connected to a separate AUX contact of the External Maintenance Bypass Switch.

10.5.3 Remote Signalling Box (RSB)
The optional Remote Signalling Box allows monitoring of the operation of the UPS, using the potential
free contacts fitted on the “P4 - Customer Interface Board“ of the UPS.
It can be used by simply putting the box on a desktop or on a wall or, removing the box, it can be
surface mounted.
The remote panel contains an internal buzzer and the following status indicators:
• Mimic diagram With LEDs indicating the operation of Rectifier and Inverter, and the
power source supplying the critical Load.
• Alarm Indicating a critical situation on the UPS (LED light and audible alarm).
• Stop Indicating the UPS is preparing to shut down in a short time.
• Mute Push button, resets the buzzer.
• Test Push button checks all the LEDs and the buzzer of the remote panel.
The cable connecting the RSB to the UPS cabinet must be min. 16 wires / 0.25mm2.
The plug B is included in the delivery of the option RSB (cable connecting UPS with RSB not included).
Maximal allowable length: 300 m (985 ft).
It must be wired at one end with a D - female plug- 25 pin (J2 – P4 Customer Interface Board).
NOTE !
The alarms on free potential contacts can be connected on terminals X1 instead J2 (see
correlation X1 – J2 in Section 9.1).

11 MAINTENANCE
WARNING !
All maintenance and service works must be performed by QUALIFIED SERVICE
PERSONNEL.
A UPS system, like other electrical equipment, needs periodic preventive maintenance.
A regular maintenance check of your installation guarantees higher reliability of your safe power
supply.
Preventive maintenance work on the UPS can be done only by trained Service technicians.
We therefore recommend you sign a Maintenance and Service contract with the local Service Centre
organisation.
Service check
If this lamp lights up during the normal operation, that means that the unit has not been serviced for the
last 20’000 hours by an GE trained technician.
We highly recommend that you contact your Service Centre for preventive maintenance work.
Fans and ventilation
We recommend a periodic cleaning of the ventilation channels and grids on the UPS system, in order to
guarantee proper air circulation in the unit and in the battery.
We recommend replacement of the fans in the units every 20’000 hours.
Other components with limited lifetime
We recommend the replacement of components such as filter capacitors and lithium battery for the
backup of data on the control boards of the units every 50’000 hours.
Battery
We recommend a periodic manual battery test, especially if the automatic battery test is disabled, in
order to verify if the battery can provide the expected backup time in case of mains failure.
We recommend this test be performed at least every 1 month, especially if the battery is not sufficiently
discharged during normal operation.
The discharge time you use should be at least half of the battery runtime.
For automatic battery test setting, a special code is required to enter User set-up parameters.
Please consider that, if you did a full battery test to verify the full runtime of the battery, the charger
needs at least 8 hours to recharge the battery up to 90% of its capacity.
Long shut-down periods of the UPS-system
To guarantee that the battery is fully charged, the UPS system should be in operation for at least 12
hours every 3 months.
If not the battery may be permanently damaged.

UPS room conditions and temperature
The UPS room and the battery room have to be maintained clean and free from dust.
A high temperature of the UPS room and of the battery room affect the lifetime of several components
inside the equipment.
The battery is very sensitive to room temperatures above 25°C (77°F).
Preventive maintenance program:
a) Cleaning, a visual inspection and a mechanical inspection of the UPS modules;
b) Replacement of defective parts or the preventive replacement of parts with a defined life time
c) “Updating” of the equipment (technical improvements subsequent to the delivery).
d) Check the calibration of DC voltage and Inverter output voltage and frequency.
e) Check of the settings of the electronic regulation, the control and the alarm circuits of the rectifier(s)
and inverter(s).
f) Functional checks on thyristors, diodes, transformers, filter components, e.g. to ensure that they
are operating within the specified design parameters.
g) Overall performance test including a mains failure simulation with and without the load.
h) Monitoring battery operation in discharge and recharge mode including any boost charge duties.
