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- tects equipment from these disturbances.

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

At least one external battery cabinet must be connected to the GXT5000R-208 to form a com- plete “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.
