INTRODUCTION AND SYSTEM DESCRIPTION Congratulations on your choice of the Liebert GXT5000R-208 Uninterruptible Power System (UPS). It provides conditioned power to microcomputers and other sensitive electronic equip- ment. Upon generation, AC power is clean and stable. However, during transmission and distribu- tion it may be subject to voltage sags, spikes, or complete power failure that may interrupt computer operations, cause data loss, and even damage equipment. The GXT5000R-208 pro- tec

MAJOR COMPONENTS Transient Voltage Surge Suppression (TVSS) & EMI/RFI Filters These UPS components provide surge protection and filter both electromagnetic interference (EMI) and radio frequency interference (RFI). They minimize any surges or interference present in the utility line and keep sensitive equipment protected. Rectifier/Power Factor Correction (PFC) Circuit In normal operation, the rectifier/PFC circuit converts utility AC power to regulated DC power for use by the inverter wh

Auxiliary 120V / 400VA Power The GXT5VBATTW120 battery cabinet also provides a transformer to provide up to 400VA of 120V power. Dynamic Bypass The GXT5000R-208 provides an alternate path for utility power to the connected load in the unlikely event of a UPS malfunction, such as overload, overtemperature, or an internal UPS failure. If a malfunction does occur, the UPS automatically transfers the connected load to bypass. Bypass operation is indicated by an alarm and illuminated Bypass LED (

Load Level indicators - 4 green, 1 amber, 1 red LEDs The Load Level indicators display the approximate load level at all times. The four green LEDs indicate acceptable levels up to 95%. The amber light comes on when the load level is 96-105%. The last LED at right (red) indicates an overload (more than 105%) and warns of immi- nent shutdown if the load is not reduced. Battery Capacity indicators - 5 green LEDs The GXT5000R-208 features an automatic battery test. The Battery Capacity LED

OPERATING INSTRUCTIONS Turn On Once the AC supply has been applied to the unit, power will be applied to the load (bypass mode) immediately when the 30 A input circuit breaker is initially closed. Turn the unit ON (inverter mode) by pressing the ON button once. Manual Bypass To manually put the unit in Bypass mode, press the Standby button once. Pressing this button once will cause the load to be transferred to bypass power. Pressing this button a sec- ond time will result in loss of pow

Five Batteries Four Batteries Three Batteries Two Batteries One Battery OPTIONAL BATTERIES - PROGRAMMABLE RUN TIME The GXT5000R-208 may be equipped with up to five battery GXT5VBATT cabinets. At least one battery cabinet is required. The first battery cabinet may be a GXT5VBATTW120 if a 120V, 400VA auxiliary voltage source is needed. The enhanced communication provides an estimated run time in minutes, taking into account the number of battery cabinets and UPS load. The number of attached

Procedure to confirm the battery count 1. Apply AC input power to the UPS. 2. Turn the UPS output off using the Standby button. If the UPS is in inverter mode, the load must first be transferred to bypass and then to off. 3. Once the UPS output is off, press and hold the Standby button continuously. The Standby button must be held continuously for the duration of this procedure. The UPS will do nothing for the first 10 seconds. After approximately 10 seconds, the LED display will scroll an
