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, 5000VA, 6000VA, 8000VA and
10,000VA.
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.
