User Manual
1.0 Product Description
The Liebert GXT4 is a compact, online uninterruptible power system (UPS) that continuously conditions
and regulates its output voltage. The UPS is designed to supply microcomputers and other sensitive
electronic equipment with clean sine wave input power.
Upon generation, AC power is clean and stable. However, during transmission and distribution it is subject
to voltage sags, spikes and complete failure that may interrupt computer operations, cause data loss and
damage equipment.
The Liebert GXT4 protects equipment from these disturbances. The Liebert GXT4 continuously charges its
batteries from the mains, enabling it to supply power to connected loads, even when the mains fail.
This section describes the UPS, its features, models, appearance and components, operating principles
and operating mode.
