Emerson GXT2U Manuel D’Utilisation

Congratulations on your choice of the Liebert GXT2U™ 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 operations, cause data loss, or even 

damage equipment. The Liebert GXT2U protects equipment from these 

disturbances.
The Liebert GXT2U is rated for 2700 VA, 1890 watts. Complete model 

specifications appear at the end of this manual. 
The Liebert GXT2U 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 sine wave 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.
