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 equipment.

Upon generation, AC power is clean and stable. However, during transmission and distribution 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 protects equipment from these disturbances.

The GXT5000R-208 has a nominal power rating of 5,000VA, 3,750 W. Complete model specifications appear at the end of this manual.

At least one external battery cabinet must be connected to the GXT5000R-208 to form a complete “on-line” UPS system. Two different models of battery cabinets are available:

•The GXT5VBATT provides batteries only.

•The GXT5VBATTW120 provides batteries and an auxiliary transformer to provide up to 400VA at 120V.

Both battery cabinets provide two battery connectors to allow the daisy-chain connection of additional battery cabinets. The UPS may be used with either battery cabinet, depending on whether the additional 120V / 400VA power supply is needed.

For applications requiring 120V, one GXT5VBATTW120 should be the first battery cabinet located adjacent to the GXT5000R-208. The GXT5000R-208 requires a one-foot interconnect cable to provide power to the internal 208V step-down transformer.

If more than one battery cabinet is desired for additional backup battery time, additional GXT5VBATTs can be added. Only one GXT5VBATTW120 external battery cabinet can be used per UPS system.

For ease of use, the GXT5000R-208 utilizes light emitting diode (LED) displays to indicate “load percentage” and “battery capacity,” and fault indications. It also provides a self-diagnos- tics test, a combination ON/Manual Battery Test button, a combination Standby/Manual Bypass button, and a variety of relay alarm contacts.

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 while ensuring that the waveshape of the input current used by the UPS is near ideal. Extracting this sinewave input current achieves two objectives: the utility power is used as efficiently as possible by the UPS, and the amount of distortion reflected on the utility is reduced. This results in cleaner power being available to other devices in the building not being protected by the GXT5000R-208.

Inverter

In normal operation, the inverter utilizes the DC output of the power factor correction circuit and “inverts” it into precise, regulated sinewave AC power. When utility power fails, the inverter takes power from the battery through the DC to DC converter and inverts it into alternating current. In both modes of operation, the UPS inverter is on-line and continuously generating clean, precise, regulated AC output power.

Battery Charger

The battery charger utilizes utility power and precisely regulates it to continuously “float” charge the battery system.

DC to DC Converter

The DC to DC converter utilizes energy from the battery system and raises the DC voltage to the optimum operating voltage for the inverter. This allows the inverter to operate continuously at its optimum efficiency and voltage, thus increasing reliability.

Battery

The GXT5VBATT and GXT5VBATTW120 employs valve-regulated, nonspillable, lead acid batteries. At an ambient temperature of 68°F to 77°F (20°C to 25°C) and with the UPS float charging, the battery design life will be maintained.

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 (other LEDs also may be illuminated to indicate the diagnosed problem). To manually transfer the connected load from the inverter to bypass, press the Standby button once.

NOTE

The bypass power path does NOT protect the connected equipment from disturbances on the utility supply, such as spikes, sags, and failure.
