1 SAFETY RULES With this document, GE gives to the user all the necessary information about the correct use of the UPS. We recommend that this manual be kept next to the UPS for future references. If any problems are encountered with the procedures contained in this manual, please contact the nearest Service Center before you proceed. All UPS installation, maintenance and service work should be performed by qualified service personnel only.
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. GENERAL - - Move the UPS in an upright position in its original package to the final destination room. Check for sufficient floor and elevator loading capacity. Check the integrity of the UPS equipment carefully. If you notice visible damage, do not install or start the UPS.
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.
2 INTRODUCTION 2.1 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.
3 DESCRIPTION 3.1 BLOCK DIAGRAM AND MAIN ELEMENTS DESCRIPTION Fig. 3.1-1 UPS block diagram 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. Communication between user and UPS is achieved by the front panel consisting of an LCD screen, displaying the operation modes, the measurements and the events / alarms.
3.2 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 the load is 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. Fig. 3.
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 is instantly transferred to the mains through the automatic bypass, taking advantage of the higher short circuit power. Fig. 3.
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. Fig. 3.
3.3 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. Parallel system for power capacity Two or more units can be paralleled in order to achieve output power superior to the maximum power delivered by a single UPS unit.
3.4 UPS PARALLELED ON THE SAME BATTERY NOTE ! 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. In case of parallel units running with a Common Battery (max. 4 UPS - see Fig. 3.
3.5 SERVICE AND TECHNICAL SUPPORT Stamp of your Dealer or local responsible of the Technical Assistance (see page 3) For any request of technical support please contact the supplier who provided the system. The requested data permitting to identify your UPS are marked on the identification label fixed on the front of the cabinet, behind the lower front door. For fast and efficient Technical Support solutions, please mention the data marked on the identification label. Fig. 3.
3.6 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. 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.
