IMPORTANT SAFETY INFORMATION

IMPORTANT! This manual contains important safety instructions that must be followed during the

1 GXT5 DESCRIPTION

The Liebert® GXT5 is a compact, online uninterruptible power system (UPS) that continuously conditions

and regulates its output voltage. The Liebert® GXT5 supplies 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.

The Liebert® GXT5 protects equipment from these disturbances. The Liebert® GXT5 continuously

charges its batteries from the mains, enabling it to supply power to connected loads, even when the mains

fail.

1.1 UPS Features and Available Models

The GXT5 includes the following features. Table 1.1 on the next page, lists the available models and

power ratings.

•Enhanced load capacity with an output power factor of 1.

•Optional tower or rack installation to meet varying installation requirements.

•Parallel-connection capability for 10-kVA, 16-kVA, and 20-kVA models achieves up to 2 + 1

parallel redundant power.

•Adapts to areas with unstable power-mains supply via high-frequency double-conversion

topology structure, with high input-power factor, wide input-voltage range, and output

immune to grid interference.

•Full digital-control platform and hardware-design platform adapts to unstable mains supply

and load impact

•Programmable terminals with cascade protection on 5-kVA to 10-kVA models protect key

devices when load is heavy.

•Innovative design layout and process greatly increase product reliability.

•Operation and display panel with model-specific color LCD offers simple configuration and

control of the UPS.

•ECO power-supply mode and smart-sleep mode help you save the maximum amount of energy.

1.2 Front Panels

The various GXT5 models have the same general appearance, with the main difference being the

receptacle types on the rear panel. Figure 1.1 below, shows the 5-kVAto10-kVA model in a tower and a

rack configuration. When mounted in a rack, the 5- to 10-kVA units are turned 90 degrees. The

orientation of the 16-kVA to 20-kVA models is the same in a rack or tower configuration.
