IMPORTANT SAFETY PRECAUTIONS ! WARNING Observe all cautions and warnings in this manual. Failure to do so may result in serious injury or death. Refer all UPS and battery service to properly trained and qualified service personnel. Do not attempt to service this product yourself. Opening or removing the cover may expose you to lethal voltages within this unit even when it is apparently not operating and the input wiring is disconnected from the electrical source. Never work alone.
The Liebert GXT4-3000RT208 was tested under 20A branch circuit in accordance with the National Electrical Code, ANSI/NFPA 70. To reduce the risk of fire, connect only to a circuit provided with 20A maximum branch overcurrent protection. Battery Safety ! CAUTION Do not dispose of batteries in a fire. The batteries may explode. Do not open or mutilate the batteries. Released electrolyte is toxic and is harmful to skin and eyes. Dispose of used batteries according to the instructions.

Product Description 1.0 PRODUCT DESCRIPTION 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.
Product Description 1.3 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. Figure 1 Liebert GXT4 rack/tower models—front view Ventilation Slots 1.3.

Product Description DC-to-DC Converter The DC-to-DC converter raises the DC voltage from the battery to the optimum operating voltage for the inverter. This allows the inverter to operate continuously at its optimum efficiency and voltage, thus increasing reliability. Battery The Liebert GXT4 uses valve-regulated, nonspillable, lead acid batteries. To maintain battery design life, operate the Liebert GXT4 in an ambient temperature of 32°F to 77°F (0°C to 25°C).
Product Description 1.5.3 Battery Mode The Liebert GXT4 enters Battery Mode when mains power fails or is outside acceptable limits. The battery system supplies power through the DC-to-DC converter to the inverter to generate clean AC power for the connected loads. When the Liebert GXT4 enters Battery Mode, the UPS sounds a half-second beep at 10-second intervals.
Installation 2.0 INSTALLATION 2.1 Unpacking and Inspection Unpack the UPS and conduct the following checks: • Inspect the UPS for shipping damage. If any shipping damage is found, report it to the carrier and your local dealer or your Emerson representative immediately. • Check the accessories included in packaging list. If there is any discrepancy, contact your local dealer or your Emerson representative immediately. 2.
Installation 2.4 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. NOTE When installing the UPS or making input and output connections, comply with all relevant safety codes and standards 2.4.1 Tower Installation To install the Liebert GXT4 as a tower: 1. Take out support bases from the accessories (see Figure 8).
Installation Figure 10 Rotate the operation and display panel Rotate Operation and Display Panel 90 degrees clockwise c. Pull the logo on the front plastic bezel cover gently, rotate it 90 degrees clockwise and snap it back into position. The rotated front plastic bezel cover is shown in Figure 11. d. Replace the front plastic bezel cover on the Liebert GXT4.

Communication 5.0 COMMUNICATION This section describes the four types of communication ports on the rear of the UPS: • • • • Liebert IntelliSlot® port USB port (standard B-type) Terminal Block Communication RS232 port (DB9F) ! CAUTION To maintain safety (SELV) barriers and for electromagnetic compatibility, signal cables should be segregated and run separate from all other power cables. 5.
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. For most users, the factory default settings are adequate. This section give a brief overview of the features and parameters that are available for modification, as well as the factory default settings.
Communication 5.3 RS-232 Port The RS-232 port uses an Emerson® proprietary protocol that is for use with Liebert MultiLink®. This port enables a more secure connection instead of the USB cable, to the computer or server that has Liebert MultiLink installed. 5.4 Terminal Block Communication The Terminal Block includes eight pins, as shown in Figure 42. Figure 42 Terminal Block Communication pin layout 5.4.
Communication 5.4.2 Battery Mode Shutdown Battery Mode Shutdown permits shutting down the UPS by turning Off the rectifier, inverter and static switch so that there is no power to the load when the UPS is On Battery. The auxiliary power for the UPS will still be active. Battery Mode Shutdown can be performed locally or remotely: • Local Battery Mode shutdown can be performed by shorting Pin3 and Pin4.
Maintenance 6.0 MAINTENANCE This section describes replacing the internal battery pack, precautions, checking the Liebert GXT4’s status and checking UPS functions. ! WARNING The battery can present a risk of electrical shock and high short circuit current. The following precautions should be observed before replacing the battery pack: • Remove rings, watches and other metal objects. • Use tools with insulated handles. • Do not lay tools or other metal objects on the batteries.
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. Lay the battery door and screws aside for reassembly. Figure 43 Removing the front bezel cover and battery door 4. Gently pull the battery wire out and disconnect the battery plug and battery receptacle, as shown in Figure 44.
Maintenance 6. Unpack the new internal battery pack. Take care not to destroy the packing. Compare the new and old internal battery pack to make sure they are the same type and model. If so, proceed with Step 7; if they are different, stop and contact your local Emerson representative, or Emerson Channel Support. 7. Line up and slide in the new internal battery pack. 8. Reconnect the battery plug and battery receptacle 9. Push the battery wire and internal battery pack back into the UPS. 10.
Troubleshooting 7.0 TROUBLESHOOTING This section indicates various UPS symptoms a user may encounter and provides a troubleshooting guide in the event the UPS develops a problem. Use the following information to determine whether external factors caused the problem and how to remedy the situation. 7.1 UPS Symptoms The following symptoms indicate the Liebert GXT4 is malfunctioning: • The relative indicators illuminate, indicating the UPS has detected a problem.
Troubleshooting 7.1.2 Audible Alarm An audible alarm will sound in conjunction with the visual indicators to indicate a change in UPS operating status. The audible alarm will sound as described in Table 11.
