Congratulations on your choice of the Liebert
®
GXT3
™
uninterruptible power system (UPS). The
Liebert GXT3 comes in nominal power ratings of 5000VA, 6000VA, 8000VA and 10,000VA. It is
designed to provide conditioned power to microcomputers and other sensitive electronic equipment.
When it is generated, alternating current is clean and stable. However, during transmission and dis-
tribution it is subject to voltage sags, spikes and complete power failure that may interrupt computer
operations, cause data loss and even damage equipment. The Liebert GXT3 protects equipment from
these disturbances.
The Liebert GXT3 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 equipment with
clean, sinewave power. Sensitive electronic equipment operates best from sinewave power.
For ease of use, the Liebert GXT3 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/Manual Bypass button and a configuration program.
The Liebert GXT3 has a Liebert IntelliSlot
®
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
®
. Liebert MultiLink can also remotely control UPS operation.
