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 Utility 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 Utility power returns.
SG Series is a true double conversion On-line UPS system where the Load is continuously
supplied by the Inverter through the Rectifier.
In case of trouble on the Inverter Output Voltage, or when overload or short-circuit on the
output occur, the Load is instantly transferred to the Utility 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 0.8 Power Factor, SG Series delivers more real power than other UPS in the
market.
With today’s trend toward power factor corrected loads, SG Series 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, SG Series UPS are controlled in a true peer-to-peer configuration where all
critical elements and functions (including Bypass) are redundant.
SG Series 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, SG Series 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 new age of power quality and power reliability.
• Extremely flexible
Tailor made power protection to meet your individual installation requirements; SG Series
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.
The SG Series system can be divided into the following main elements:
Fig. 3.1-1 Block diagram
Control System SG Series 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 Utility 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 ACvoltage 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 Utility.
Back-feed Protection
All SG Series 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 and K8 (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 Manual Bypass Q2.
Manual Bypass The Manual Bypass consists of a pair of manual switches (Q1

Q2)
Battery The Battery supplies the DC power to the Inverter when the
During normal operation, the Rectifier
converts input AC power to DC.
The DC power provides input power for the
Inverter and charging power for the Battery.
The Inverter converts the DC power to
continuous and regulated AC power, which
supplies the critical load.
The control panel reports the Battery charge
status and the expected backup time with the
actual load.
3.2.2 Utility failure operation
When the Utility 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

critical load.

When the Battery is recharged enough 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.
When the AC input power recovers, the Rectifiers will start up sequentially, according to their
number in the parallel system. This minimizes the

a
minimum runtime
When enough Inverters to supply the Load have been restarted, the Load will be transferred
from the Automatic Bypass back to the Inverter output.
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 Utility 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.
In case of parallel operation
Each unit has it’s 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, it’s Bypass circuit remains available to the parallel system.
It is excluded only if the unit is separated from the common bus by opening it’s output switch Q1.
3.2.5 Manual Bypass
FIG. 3.2.4-1 BLOCK DIAGRAM AUTOMATIC
BYPASS
The Manual Bypass circuit consists of Q1 and Q2
manual switches, which permits transfer of the
Load directly to the unconditioned AC power
without interruption, leaving the UPS available for
maintenance.
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
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 Utility Bypass source.

Fig. 3.3.1-1 Block diagram parallel system operation
The SG Series parallel system is designed to provide a complete
Architecture, and is free from common equipment.
Not only the Inverters are redundant, but also the Bypass functions are designed with
redundant modular concept.
When one UPS needs maintenance or service, the Load is powered by the other units
supplying the Load bus.
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.

Redundant Parallel
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 Utility Bypass voltage, as long as
the later 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.
It is strongly recommended that no transformers, automatic circuit
breakers or fuses should be inserted between the unit’s output and theLoad common bus bars.
However, it is recommended that a disconnect or isolation switch be
inserted.
A parallel system with a Common Battery for two or more Rectifiers,
requires a particular installation and adequate setting of some
parameters, (accessible only through password), and can therefore
only be done by a qualified engineer from GE.
Usually each Rectifier-Inverter Unit runs with its own Battery.
In case of parallel units are running with a Common Battery (max. 4 UPS - see Fig 4.12-1), the
sharing circuit between individual Rectifier is integrated in the communication bus of the
system in order to assure an equal sharing of the Rectifiers output currents.

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 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.
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.

particularly unstable in frequency, it should be suitable to install the signal “Generator ON”
on X1/11, 22 or J2/11, 24 (this input is programmed as default for this function).
When this contact closes, it causes the change of certain functions (programmable) such as:
Enabling or disabling of synchronization and consequently the Load transfer to generator.

8.1.5 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 customer interface of each unit must
be connected to a separate AUX contact of the External Maintenance
Bypass Switch.

A UPS system, like other electrical equipment, needs periodic preventive maintenance.
A regular maintenance check of your installation guarantees higher reliability of your safe critical
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 GE Global Services
@ 1-800-637-1738
10.1.1 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 a GE trained technician.
We highly recommend that you contact your
Service Center
for preventive maintenance work.
10.1.2 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
.
10.1.3 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.
10.1.4 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 Utility Failure.
We recommend this test be performed at least every 3 months, 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.
The start up technician has access to this code and can program this feature during start up.
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.
It is recommended to note in this section Notes, with date and short description all the
operations performed on the UPS, as: maintenance, components replacement, abnormal
situations, etc.
