Chapter 1   Introduction 
Congratulations on your choice of the Liebert® GXT4™ uninterruptible power system (UPS). The Liebert GXT4 
comes in nominal power ratings of 5000VA, 6000VA 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 distribution 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 GXT4 protects equipment from these disturbances. 
The Liebert GXT4 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. 
The Liebert GXT4 features a multicolor LCD display to indicate load percentage, input/output voltage and current, 
runtime of battery and so on. It also provides self-diagnostic tests by visual configuration. 
The Liebert GXT4 can be operated at high efficiency mode (Green Mode) which efficiency could up to 97%. 
The Liebert GXT4 includes E models without rack slide kits for different requirement of user. 
The Liebert GXT4 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.
