    DESCRIPTION BLOCK DIAGRAM AND MAIN ELEMENTS Fig. 4.1-1 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.

  • Page 13: Operation Modes

    OPERATION MODES 4.2.1 Normal operation mode VFI (Voltage Frequency Independent) Under normal conditions load 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...

  • Page 14: Mains Failure Operation

    4.2.3 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.

  • Page 15: 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 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...

  • Page 16: Parallel System Operation

    PARALLEL SYSTEM OPERATION 4.3.1 Introduction to the Parallel System Fig. 4.3.1-1 Block diagram Parallel System operation 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 17: Features Of Rpa Parallel System

    4.3.2 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 UPS units are connected keeps each unit informed about the status of all the other units.

  • Page 18: Rectifiers Paralleled On The Same Battery

    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.

    VENTILATION AND COOLING Fig. 5.5-1 Installation on plain floor Fig. 5.5-2 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.

  • Page 26: Unpacking

    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.
  • Page 27 For Parallel Systems, the delivery also includes the bus control cables for inter- connecting 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.

  • Page 35: Functioning As Frequency Converter

    5.8.3 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.
