g GE 1 IMPORTANT SAFETY INSTRUCTIONS SAVE THESE INSTRUCTIONS This manual contains important instructions for models SG Series 50 and 80 kVA that should be followed during installation and maintenance of the UPS and battery. 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. Check for sufficient floor and elevator loading capacity.
g GE 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 AND REFER TO THE BATTERY MANUFACTURERS INSTALLATION MANUAL BEFORE HANDLING THE UPS AND BATTERY. UPS INTENDED TO BE USED WITH A REMOTE BATTERY SUPPLY – ALL MODELS: “PLEASE REFER TO THE BATTERY MANUFACTURER’S INSTALLATION MANUAL FOR BATTERY INSTALLATION AND MAINTENANCE INSTRUCTIONS”.
g GE 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. Please pay attention to the meaning of the following warnings and symbols.
g GE 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 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.
g GE 3 3.1 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. This monitoring system consists of an active mimic diagram, a keyboard and a backlit display.
g GE 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. 3.2.2 Fig. 3.2.
g 3.2.3 GE 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.
g GE 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.
g 3.3.2 GE 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.
g 3.4 GE 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. 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.
g 3.5 GE RECYCLING AT THE END OF SERVICE LIFE NOTE! This product has been designed to respect the environment, using materials and components respecting eco-design rules.

g GE alarm service check General alarm condition. It blinks when one or more alarm is activated. The internal buzzer is ON. The LED remains lighted (with alarm condition still present) and the buzzer stops as the key “mute” has been pressed. LED ON indicates that a regular maintenance service is needed. May be reset by a service technician only. (See chapter 10 – Maintenance) THE LED IS ON ALSO WHEN THE OUTPUT SWITCH Q1 IS OPEN, INDICATING THAT THE INVERTER IS IN SERVICE MODE, NOT SUPPLYING THE LOAD.
g GE 6 LCD SCREEN The user interface consists of a back lit LCD screen having: • 4 lines with 20 characters (standard version for Latin characters). And • 6 keys (the function is described for each operating mode). The operation is extremely simple and is structured on three important main menus related to the UPS operation, as follows: metering A UPS must offer some metering information for the user to be able to examine the operating status at any time.

g GE 10 10.1 MAINTENANCE 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 @ 1-800-637-1738 10.1.
g GE 10.1.5 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. 10.1.6 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.
g GE 11 11.1 NOTES NOTES FORM 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. Date OPM_SGS_USM_10K_40K_0US_V010.
