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.
1.1 Features
The UPS includes these features:
• Intelligent battery management to extend battery life
• LCD for user-friendly operation and local monitoring and configuration of operational parameters
• Flexible network management with Liebert MultiLink®software
• Fan fault self-inspection and automated diagnostic function
• Intelligent fan operation, automatically changing rotation speed depending on system requirements, to
decrease power consumption and noise
• Input circuit breaker to ease recovery from overloads
• CE mark and safety approval from CE
• Communication options: USB port, Liebert IntelliSlot®port and terminal block communication
• Dry contacts for remote monitoring
• Input power factor greater than 0.99
• Output voltage selection function
1.2 Available Models

1.5 Internal Battery Packs
The UPS has two internal battery packs behind a battery access door on the front of the unit. Each internal
battery pack is fitted with a connector to link to the UPS.
Figure 1-8 Internal battery pack with connector
1.6 Major Components
The UPS is composed of mains input, TVSS and EMI/RFI filters, rectifier/PFC, inverter, battery charger,
DC-to-DC converter, battery, dynamic bypass and UPS output.
1.6.1 Transient Voltage Surge Suppression (TVSS) and EMI/RFI Filters
These UPS components provide surge protection and filter both electromagnetic interference (EMI) and
radio frequency interference (RFI). They minimize any surges or interference present in the mains line and
keep the sensitive equipment protected.
NOTE
GXT4 10,000-VA battery pack shown in Figure 1-8. 5000-VA and 6000-VA
battery packs have the same features.
