Page 178: Description
DESCRIPTION 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.
Page 179: Operation Modes
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.
Page 180: Utility Recovery Operation
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.

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.
Page 182: Features Of Rpa Parallel System
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.

(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.

GENERAL Move the UPS in an upright position in its original package to the final destination room. To lift the cabinets, use a forklift or lifting belts with spreader bars.
Page 294 Safety instructions when working with battery EXTERNAL BATTERY MUST BE INSTALLED AND CONNECTED TO THE UPS BY QUALIFIED SERVICE PERSONNEL. INSTALLATION PERSONNEL MUST READ THIS ENTIRE SECTION BEFORE HANDLING THE UPS AND BATTERY. DANGER! Full voltage and current are always present at the battery terminals. The battery used in this system can provide dangerous voltages, extremely high currents and a risk of electric shock.
Page 295 Safety symbols and warnings Safety warnings The text of this manual contains some warnings to avoid risk to the persons and to avoid damages to the UPS system and the supplied critical loads. The non-observance of the warnings reminding hazardous situations could result in human injury and equipment damages.
Page 296: Introduction
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.
Page 297: Description
DESCRIPTION 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.
Page 298: Operation Modes
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.
Page 299: Utility Recovery Operation
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.
Page 300: Parallel System Operation
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.
Page 301: Features Of Rpa Parallel System
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.
Page 302: Rectifiers Paralleled On The Same Battery
(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.
Page 303: Recycling At The End Of Service Life
It does not contain CFCs (Carbon Fluor Clorid) or HCFCs (Halogen Carbon Fluor Clorid). GE, in compliance with environment protection recommends to the User that the UPS equipment, at the end of its service life, must be recovered conforming to the local applicable regulations.

Page 422: Utility Failure Operation
4.2.3 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.
Page 423: Automatic Bypass
4.2.5 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 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.
Page 424: Parallel System Operation
PARALLEL SYSTEM OPERATION 4.3.1 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.
Page 425: Features Of Rpa Parallel System
4.3.2 Features of RPA parallel system The SG Series 225 & 300 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.
Page 426: Rectifiers Paralleled On The Same Battery
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.
