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 UPS is designed to supply microcomputers and other sensitive electronic equipment with clean sine wave input power, 700VA to 3000VA at 230V. Upon generation, AC power is clean and stable.
Product Description 1.3 Appearance and Components 1.3.1 Appearance 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 models differ largely in the type of receptacles each has. Figure 1 Liebert GXT4-700RT230 - GXT4-3000RT230 UPS Ventilation Slots 1.3.

Product Description 1.4 Major Components The operating principle of the UPS is shown in Figure 6.
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, increasing reliability. Battery The Liebert GXT4 utilizes valve-regulated, nonspillable, lead acid batteries. To maintain battery design life, operate the Liebert GXT4 in an ambient temperature of 0°C to 25°C (32°F to 77°F).
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 Emerson® representative immediately. • Check the accessories against the delivery list. If there is any discrepancy, contact your local dealer or your Emerson representative immediately. 2.
Installation Installation Clearances Maintain a clearance of at least 100mm (4 inches) in the front and rear of the Liebert GXT4. Do not obstruct the air inlets on the front panel or rear panel of the UPS—blocking the air inlets reduces ventilation and heat dissipation, shortening the service life of the Liebert GXT4. 2.4 Mechanical Installation The Liebert GXT4 may be installed as a tower or in a rack, depending on space and use considerations.
Installation 5. Place the Liebert GXT4 and any battery cabinets on the support bases. Each Liebert GXT4 needs four support bases, as shown in Figure 9. Figure 9 Tower installation Liebert GXT4 UPS and External Battery Cabinet Liebert GXT4 UPS Operation and Display Panel Rotated for Tower Operation Support Bases Support Bases 2.4.2 Rack Installation 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.
Installation For North America Installations Detachable Power Supply Cord Not Provided. Power Supply Cord Selection (for units which power supply cord not furnished with) - Use UL Listed detachable power supply cord, three conductors, minimum 4.5 ft. (1.5m), maximum 14.8 ft. (4.5m) long. Types SP-2, SP-3, SV and similar cords may be provided if the cord is not long. Refer to Tables 3 and 4 for details.
Installation 2.5.2 Connecting Battery Cables 1. Verify that the battery isolation breaker is in the Off (open) position. 2. Take out the battery cable included with the battery cabinet. 3. Connect one end of the battery cable to the external battery connector on the rear panel of the UPS, and connect the other end to any battery port on the rear panel of the battery cabinet. 4. Repeat Steps 1 through 3 for each battery cabinet that will be connected to the system.

Operation 4.0 OPERATION This section describes checks to be made before starting the UPS, how to start the UPS, manual battery test, manual bypass, shutting down the 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. 4.
Operation 4.5 Shut Down the Liebert GXT4 To shut down the UPS from the LCD: 1. 2. 3. 4. From the Main Menu select CONTROL, press Enter, then select TURN ON & OFF. Press the enter key. Select TURN UPS OFF, then press Enter. Press either the Up or Down button to move the cursor to confirm the shutdown command and press Enter. The UPS will sound an audible alarm; this is normal. Power to the connected equipment is now Off. 5.
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 USB Port Communication The standard B-type USB port is used to connect the UPS and network server or other computer system using Liebert MultiLink®. A standard B-type USB port is provided to allow connection to a computer or network server. The USB port can be used to communicate with the Liebert GXT4 configuration program (see section 5.2.1 for details) or Liebert MultiLink (refer to 5.1.1 - Liebert MultiLink for description) that is provided on the CD that is included with the UPS. 5.
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 40. Figure 40 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. Gently remove the front plastic bezel cover from the UPS. 2. Loosen and remove the six screws on the battery door, as shown in Figure 41. 3. Lay the battery door and screws aside for reassembly. Figure 41 Removing the front plastic bezel cover and battery door 4. Gently pull the battery wire out and disconnect the battery plug and battery receptacle, as shown in Figure 42.
Maintenance 10. Reattach the front battery door with the six screws. 11. Reattach the front plastic bezel cover to the UPS. NOTE The internal battery pack is hot-swappable. However, caution should be exercised because during this procedure the load is unprotected from disturbances and power outages. Do not replace the battery while the UPS is in Battery Mode. This will result in a loss of output power and will drop the connected load. 6.
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.
