Introduction NTRODUCTION Congratulations on your choice of the Liebert GXT3 uninterruptible power system (UPS). The Liebert GXT3 comes in nominal power ratings of 5000VA, 6000VA, 8000VA and 10,000VA. It is designed to provide conditioned power to microcomputers and other sensitive electronic equipment. When it is generated, alternating current is clean and stable.
System Description YSTEM ESCRIPTION Output Input Static Bypass TVSS & Rectifier/PFC EMI/RFI DC-to-DC Filters Converter Inverter Battery Battery Charger 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 util- ity line and keep the sensitive equipment protected.
System Description Battery The Liebert GXT3 utilizes valve-regulated, nonspillable, lead acid batteries. To maintain battery design life, operate the UPS in an ambient temperature of 15°C to 25°C (59°F to 77°F). Optional external battery cabinets are available to extend battery run times. For run times, see Table 14. Dynamic Bypass The Liebert GXT3 provides an alternate path for utility power to the connected load in the unlikely event of a UPS malfunction.

Installation and Configuration 6. If available, apply a bead of grease 1" (25mm) long at four Apply places inside the bottom, curved tracks of the front members grease as shown below right. The grease will allow the equipment to UPS or slide into the bracket assemblies more easily..
3. Securing hardware and slide rails are sold separately. Please contact your local dealer or Emerson representative for these additional options and any assistance needed. Fasten the slides into position with the screws per the instructions included with the slide rails.
Installation and Configuration NOTE If the UPS is to be shipped or stored for an extended time, the connector should be disconnected. This will minimize any standby current drain on the batteries and help attain their design life. Connect Input/Output Power WARNING Risk of electric shock.
Installation and Configuration 5.3.2 Remove the Power Distribution Cover from 8000 and 10,000VA Models 1. Shut down the Liebert GXT3 by pressing the Standby/Manual Bypass button twice while the UPS is in Bypass Mode, each time holding the button down for about 2 seconds. (For help, refer to 8.5 - Shut Down the Liebert GXT3.) 2.
Installation and Configuration 5.3.4 Install the Power Distribution Box on 8000 and 10,000VA Models 1. With the cover or distribution box removed, press the UPS and distribution box connectors together. Ensure that the connectors are fully seated. 2. Align the screw holes and press the power distribution box onto the UPS, making sure that the tabs at the bottom of the box fit into the slots on the UPS.
Installation and Configuration Terminal Block Connections Conduit entry holes are provided on the rear and side of the box. Input and output wiring should not share the same conduit. Emerson recommends using strain relief when installing the wire. Table 2 Electrical specifications...
Installation and Configuration IT Power System Configuration—Liebert GXT3-6000RTL630 Only WARNING Risk of electric shock. Can cause injury or death. Disconnect all local and remote electric power supplies before working within. Ensure that the Liebert GXT3 is shut down and power has been disconnected before beginning any work on or in the unit.
Configuration Program ONFIGURATION ROGRAM The final step of installation may require custom configuration of your UPS using the enclosed config- uration program. Some configuration settings may be changed only while the UPS is off. These should be set before the UPS is put into full-time service powering the critical load. For most users operating with 230VAC and with no external batteries, the factory default settings will be adequate.
• After 24 hours, retest the batteries. • After the batteries have been retested, if only three of the five Battery LEDs illuminate, contact your local dealer, Emerson representative or Emerson Channel Support. Standby/Manual Bypass Button This button controls output power to connected load(s) and has dual functions: Standby and Manual Bypass.
Controls and Indicators Load Level Indicators (4 Green, 1 Amber) The load level indicator is composed of five sets of LED bars that illuminate to indicate the relative load on the UPS output in 25% increments (±5%). The load level indicator will illuminate as shown in Figure 19.
Controls and Indicators UPS Status Indicators UPS status is indicated by five symbols: fault indicator, AC input indicator, battery indicator, inverter indicator and bypass indicator. Table 3 shows the symbols and their meanings. Table 3 UPS status indicators UPS Status Indicator Icon Color...
Operation PERATION This section describes checks to be made before starting the UPS, how to start the UPS, manual bat- tery test, manual bypass, shutting down the UPS and disconnecting the utility power from the UPS. NOTE The Liebert GXT3’s battery has been fully charged before delivery, but some charge will be lost during storage and shipping.
• If none of the five Battery LEDs illuminate during the second manual battery test, replace batter- ies and contact your local Emerson representative or Emerson Channel Support. Put the Liebert GXT3 in Manual Bypass Press the Standby/Manual Bypass button and hold it for about 2 seconds while the UPS is in Utility (AC) Mode.

Specifications 12.1 Auto-Learning Battery Run Times As batteries age, the estimated runtimes may become less accurate. The Liebert GXT3 is pro- grammed to “learn” from a full battery discharge and modify the estimated run time for the measured battery capacity. This can improve accuracy and compensate for aging batteries or batteries that operate at different ambient temperatures.
