GXT3 is a compact, online uninterruptible power system (UPS) that continuously conditions and regulates its output voltage. The Liebert GXT3 is designed to supply microcomputers and other sensitive electronic equipment with clean sine wave input power, 700VA to 3000VA at 230V.
DC-to-DC converter, battery, dynamic bypass and UPS output. Transient Voltage Surge Suppression (TVSS) and EMI/RFI Filters The Liebert GXT3 has surge protection and filters that protect the connected load from power surges and sags, electromagnetic interference (EMI) and radio frequency interference (RFI). These features can minimize any surges or interference present in the mains power.
UPS. Inverter In normal operation, the Liebert GXT3’s inverter utilizes the DC output of the PFC circuit to produce precise, regulated sine wave AC power. When mains power fails, the inverter receives DC power from the battery through the DC-to DC converter. In either operation mode, the UPS inverter is online, continuously generating clean, precise, regulated AC output power.
• Frequency Converter - 50Hz – Bypass Disabled • Frequency Converter - 60Hz – Bypass Disabled NOTE The default for all models of the Liebert GXT3 is “Auto Sensing - 50Hz or 60 Hz – Bypass Enabled.” CAUTION Do not touch the AC input receptacle when the UPS is operating. AC input voltages may still...
Installation Clearances Maintain a clearance of at least 100mm (4 inches) in the front and rear of the Liebert GXT3. Do not obstruct the air inlets on the front panel and rear panel of the UPS; blocking the air inlets reduces...
The Liebert GXT3 may be installed as a tower or in a rack, depending on space and use considerations. The Liebert GXT3 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.

3. Once the inverter LED has been illuminated, turn On the connected loads. 4. Check the status indicators to determine whether the Liebert GXT3 is operating normally. 5. Check the load level indicators to verify that the connected load does not exceed the UPS’s rated capacity.
UPS will shut down about 30 seconds after the button is pressed. Power to the connected loads is now Off. Disconnecting Input Power from the Liebert GXT3 1. After the UPS has been shut down as detailed in 4.5 - Shut Down the Liebert® GXT3™, disconnect the input cable plug.
The Liebert IntelliSlot 485 Card is used to connect the UPS and a BMS. Follow instructions provided with the Liebert IntelliSlot card to configure Liebert MultiLink, the UPS or any additional ancillary product for the Liebert GXT3. These instructions are available at: multilink.liebert.com 5.1.1...
The output voltage settings cannot be changed while the UPS is On and powering connected loads. NOTE Programming the output voltage of a 230V model of the Liebert GXT3 to 220V automatically derates the UPS to 96% of both the VA and Watt ratings (refer to 9.0 - Specifications for VA and Watt ratings).
Communication Terminal Block Communication The Terminal Block includes eight pins, as shown in Figure 20. Figure 20 Terminal Block Communication pin layout Any Mode Shut Down Battery Mode Shut Down Battery Mode Low Battery 5.3.1 Any Mode Shutdown The purpose of Any Mode Shutdown is to shut down the UPS output by turning Off the rectifier, inverter and static switch so that there is no power to the loads.
This timer cannot be stopped once triggered. If the mains power returns during this countdown, the Liebert GXT3 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.
