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 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 VFI (Voltage Frequency Independent) 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.

DESCRIPTION
3.1
BLOCK DIAGRAM AND MAIN ELEMENTS
Fig. 3.1-1 Block diagram
The SG Series system can be divided into the following main elements:
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 3phase 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 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 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 and Q2), which
removes the UPS from the Load for maintenance, while still supplying the Load with power directly from
the Utility.

Operating Manual SG Series 100 – 120 - 150 kVA
3.2
OPERATION MODES
3.2.1 Normal operation mode
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.
Fig. 3.2.1-1 Block diagram normal operation mode
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
the estimated time the Battery can support the
critical load.
Prior to the Battery completely discharging, the
"stop operation" alarm (shutdown imminent)
warns the operator that the Battery is almost
discharged and the UPS is about to shut down.
Fig. 3.2.2-1 Block diagram Utility Failure operation
In case of parallel operation
With a parallel system for power capacity (see Section 3.3)
• With the Bypass Utility power available, a low Battery warning on any unit will cause the Load to
be transferred to Utility (after a selectable time delay).
• With Bypass Utility power not available, a low Battery 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.

Operating Manual SG Series 100 – 120 - 150 kVA
3.2.3 Utility 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 Utility
through the Automatic Bypass.
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.
Fig. 3.2.3-1 Block diagram Utility 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 recharged enough 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.
3.2.4 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
Utility without interruption.
When the Inverter recovers, or the overload or shortcircuit 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. 3.2.4-1 Block diagram Automatic Bypass
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
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.

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 Utility Bypass source.
Parallel units for redundancy
The nominal power rating of the n+1 out of n redundant paralleled modules must be equal to or greater
than the required Load power.
The Load will be equally shared by the n units connected on the output bus.
Should one of the n paralleled units trip Off-line, the remaining (n+1) 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 SG Series parallel system is designed to provide a complete Redundant Parallel 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.
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 it's own function and operational status and communicates with all other
modules, in order to act or react if necessary, adapting it 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 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.
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 disconnect or isolation switch be inserted.

RECTIFIERS PARALLELED ON THE SAME BATTERY
NOTE !
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 3.4-1), 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.

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 clockwise phase rotation for each unit.
•
Each Rectifier must be set for the same floating DC voltage and the same Battery current limitation.
•
It is recommended to install the fuses / MCB (7) on each line connecting the Rectifiers to the
common Battery for maintenance / safety reasons.
•
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 4.1 of the “Installation Guide”).
•
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 for automatic battery floating voltage compensation.
•
Do not enable the function Boost charge (parameter 87).

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.

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:

OPTIONS
8.1 COMMUNICATION OPTIONS
Advanced SNMP Card
Simple Network Management Protocol
The Advanced SNMP Card is an interface to the Ethernet Network,
and provides UPS information via the standard SNMP Protocol
(UPS-MIB (RFC-1628); GE Single MIB; GE Parallel MIB).
The UPS can therefore be managed by a Network Management
System (NMS) or by our applications (for instance JUMP), which
uses this information to determine the state of the UPS in order to
guarantee safe and orderly shutdown of the server, when
needed.

MAINTENANCE
WARNING !
All maintenance and service works must be performed by QUALIFIED SERVICE
PERSONNEL.
9.1
MAINTENANCE
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 @ 1800-637-1738
9.1.1 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 Centre for preventive maintenance work.
9.1.2 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.
9.1.3 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.
9.1.4 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.

9.1.5 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.
9.1.6 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 77°F (25°C).
9.1.7 Long shut-down periods of the UPS-system
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 lifetime
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 Utility Failure simulation with and without the Load.
h)
Monitoring Battery operation in discharge and recharge mode including any boost charge duties.
