Introduction

1.0INTRODUCTION

Congratulations on your choice of the Liebert UPStation GXT2-6000RT230 and GXT2-4500RT230 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 opera- tions, cause data loss, or even damage equipment. The UPStation GXT2 protects equipment from these disturbances.

The UPStation GXT2 comes in nominal power ratings of 4500 VA and 6000 VA. Complete model spec- ifications appear at the end of this manual.

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

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

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