Introduction and System Description

2.0INTRODUCTION AND SYSTEM DESCRIPTION

Congratulations on your choice of the Liebert UPStation GXT2-6000RT208 Uninterruptible Power Supply (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 distribution it is subject to voltage sags, spikes or complete power failure that may interrupt computer operations, cause data loss or even damage equipment. The UPStation GXT2-6000RT208 protects equipment from these disturbances.

The UPStation GXT2-6000RT208 is a compact, on-line UPS. An on-line UPS continuously conditions and regulates its output voltage whether utility power is present or not. It supplies connected equip- ment with clean sinewave power. Sensitive electronic equipment operates best from sinewave power.

For ease of use, the UPStation GXT2-6000RT208 features a light-emitting diode (LED) display to indicate both load percentage and battery capacity. It also provides self-diagnostic tests, a combina- tion ON/Alarm Silence/Battery Test button, a Standby button, user configurable program and two levels of alarms when the unit is operating on battery.

The UPStation GXT2-6000RT208 has an interface port for communication between the UPS and a network server or other computer systems. This port provides detailed operating information includ- ing voltages, currents and alarm status to the host system when used in conjunction with Liebert’s MultiLink™ software. MultiLink software can also control UPS operation remotely.
