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.
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.
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.
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.
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.
Installation Mechanical Installation The Liebert GXT4 may be installed as a tower or in a rack, depending on space and use considerations. The Liebert GXT4 may be used alone, as a single UPS, or with up to four battery cabinets.
The Liebert GXT4 UPS and external battery cabinets (EBC), when installed in a rack enclosure, must be supported by a shelf or rack-mount rails. The Liebert GXT4 UPS and EBC units ship with all required hardware to allow rack-mount installation (not included with model numbers that end in “E”).
Installation Cable Connection The Liebert GXT4 rear panel has an input cable and plug, output receptacles and output cable(s) (Output cables are on GXT4-3000 models only). Refer to 1.3.2 - Rear Panel Features for details. The battery cables are supplied with the battery cabinet.
Installing the Optional Liebert IntelliSlot Card and Communication Cables 1. Remove the protective cover of the Liebert IntelliSlot port on the Liebert GXT4 and set it aside. 2. Insert the Liebert IntelliSlot card into the Liebert IntelliSlot port and secure it with screws.

UPS and disconnecting mains power from the UPS. NOTE The Liebert GXT4’s battery has been fully charged before delivery, but some charge will be lost during storage and shipping. To ensure that the battery has adequate reserve power to protect the connected load, charge the battery for three hours before putting the UPS into service.
Disconnecting Input Power from the Liebert GXT4 1. After the UPS has been shut down as detailed in 4.5 - Shut Down the Liebert GXT4, disconnect the input cable from the wall socket. 2. Wait 30 seconds and verify that all indicators have turned Off and the fan has stopped; this indicates that the power-off is complete.
Follow instructions provided with the Liebert IntelliSlot card to configure Liebert MultiLink , the ® UPS or any additional ancillary product for the Liebert GXT4. These instructions are available at: multilink.liebert.com 5.1.1 Liebert MultiLink Liebert MultiLink monitors the UPS continuously and can shut down the computer or server in the event of an extended power failure.
Communication 5.2.1 Configuration Program The configuration program is on the Liebert GXT4 CD and can be used instead of making configuration setting changes from the LCD panel. The configuration program communicates to a ® ® computer running a Microsoft Windows operating system via the included USB cable.
When the Auto-Enable output option is selected and the UPS output is disabled using Pin 1 and Pin 2, the Liebert GXT4’s output can turn On automatically and without warning if the Pin 1 and Pin 2 connection is changed.
This timer cannot be stopped once triggered. If the mains power returns during this countdown, the Liebert GXT4 will still shut down and must remain shut down for 10 seconds. Whether the UPS turns back On when the power is restored depends on the auto-restart setting.
• Handle, transport and recycle batteries in accordance with local regulations. Replacing the Internal Battery Pack The Liebert GXT4 is designed to allow the user to replace the internal battery pack safely. Refer to Table 9 for internal battery pack part numbers for Liebert GXT4 UPS:...
Maintenance 6.1.1 Battery Replacement Procedures 1. Remove the front plastic bezel cover from the UPS. 2. Loosen and remove the six screws on the battery door, as shown in Figure 43. 3.
