If any problems are encountered with the procedures contained in this manual, please contact the nearest Service Center before you proceed.

  • Page 7: Save These Instructions

    This manual contains important instructions for models LP 33 Series / 50 & 60 kVA that should be followed during installation and maintenance of the UPS and battery. Move the UPS in an upright position in its original package to the final destination room.

  • Page 8: Safety Symbols And Warnings

    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 9: Introduction

    INTRODUCTION GENERAL DESCRIPTION The LP 33 Series Uninterruptible Power Supply (UPS) provides the energy supply for critical loads which need a reliable, continuous free from voltage disturbances and frequency fluctuations supply. In case the mains fails, or it exceeds the permitted tolerances, the energy to supply the load is furnished by the battery with a backup time dependent on its capacity, until the mains recovers.

  • Page 10: Description

    DESCRIPTION BLOCK DIAGRAM AND MAIN ELEMENTS DESCRIPTION The Uninterruptible Power Supply System LP 33 Series / 50 & 60 kVA can be divided into the following main elements: Electronics The UPS is designed with a microprocessor–controlled supervision and diagnostic system.

  • Page 11: Operation Modes

    OPERATION MODES This section describes the different possible operation modes of the UPS explaining the function of the main modules of the UPS. VFI (Voltage Frequency Independent) Mode operation Under normal conditions 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.
  • Page 12 Automatic bypass operation In VFI (Voltage Frequency Independent) operation mode, the load is permanently supplied by the inverter but, in case of trouble on the inverter, or when overload or short-circuit on the output occur, if the mains voltage do not exceed the admitted tolerances, the load transferred to the mains through the automatic bypass, taking advantage of the higher short...
  • Page 13 Manual bypass operation The manual bypass circuit consisting of Q1 and Q2 manual switches, permits the transfer of the load directly to the mains without interruption, leaving the UPS galvanically separated from the output load. This type of operation is normally used when the UPS system must be completely turned off for maintenance or reparation.

  • Page 14: Rpa Parallel System

    RPA PARALLEL SYSTEM The RPA (Redundant Parallel Architecture) allows to extend the unit to a parallel system with 2, 3, or 4 units LP 33 Series connected on the same bus, which ensure the highest reliability rate and increase the power availability.

  • Page 15: Ups 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.
