2.0 INTRODUCTION
Congratulations on your choice of the Liebert GXT2U™ Uninterrupt-
ible Power System (UPS). It provides conditioned power to microcom-
puters 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 Liebert GXT2U
protects equipment from these disturbances.
The Liebert GXT2U comes in nominal power ratings of 500, 700, 1000,
1500, 2000 and 3000 VA. Complete model specifications appear at the
end of this manual.
The Liebert GXT2U is a compact, “on-line” UPS. An on-line UPS con-
tinuously conditions and regulates its output voltage, whether utility
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 Liebert GXT2U features a light-emitting diode
(LED) display to indicate either load percentage or battery capacity
depending upon the mode of operation. 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 Liebert GXT2U 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, currents,
and alarm status to the host system when used in conjunction with
Liebert MultiLink™ software. Liebert MultiLink software can also
remotely control UPS operation.
