Page 10: Product Description
ESCRIPTION The Liebert GXT4 is a compact, online uninterruptible power system (UPS) that continuously conditions and regulates its output voltage. The Liebert GXT4 is designed to supply microcomputers and other sensitive 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. -
Page 11: Appearance And Components
1.3.1 Front Panel and Controls The Liebert GXT4 rack/tower models in various power ratings have the same general appearance, controls and features (see Figure 1). The various rack/tower and minitower models differ largely in the type of receptacles each has. -

DC-to-DC converter, battery, dynamic bypass and UPS output. Transient Voltage Surge Suppression (TVSS) and EMI/RFI Filters The Liebert GXT4 has surge protection and filters that protect the connected load from power surges, electromagnetic interference (EMI) and radio frequency interference (RFI). These features can minimize any surges or interference present in the utility power. -
Page 15: Operating Mode
Optional external battery cabinets are available to extend battery run times. Dynamic Bypass The Liebert GXT4 provides an alternate path for utility power to the connected loads in the unlikely event of a UPS malfunction. Should the Liebert GXT4 have an overload, overtemperature or UPS failure condition, the UPS automatically transfers the connected loads to bypass. -
Page 16: Battery Mode
NOTICE Risk of loss of power to the connected load. Can cause equipment damage. Turning Off the Liebert GXT4 when it is in Battery Mode will result in loss of output power to the connected load. If the UPS is turned Off manually, it must be manually restarted after mains power returns. -
Page 17: Installation
Operating the Liebert GXT4 in temperatures above 77°F (25°C) reduces battery life. Installation Clearances Maintain at least 4 inches (100mm) clearance in the front and rear of the Liebert GXT4. Do not obstruct the air inlets on the front panel and rear panel of the UPS; blocking the air inlets reduces ventilation and heat dissipation, shortening the service life of the Liebert GXT4. -
