PP885 3BSE069276R1 Touch screen

When the GXT4 enters Battery Mode, the UPS sounds a half-second beep at 10-second intervals. When approximately 2 minutes of run time remains, the beeps sound every 5 seconds to warn that the battery is getting low (this Low Battery Warning is user-configurable). In Battery Mode, the battery indicator will illuminate and the LCD will show the prompt utility power not availab le. Press either the Up or Down button once, then press the Enter button to clear the prompt and silence the audible alarm. Once the alarm prompt has been acknowledged, the screen showing the estimated battery run time and battery capacity will be visible. Refer to Troubleshooting on page 49. For approximate battery run times, refer to Table 9.5 on page 57. NOTICE Risk of loss of power to the connected load. Can cause equipment damage. Turning Off the 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. If the UPS is turned Off by a communication signal or because the batteries are depleted, it will operate as set in the configuration program for Auto-Restart (Refer to Configuration Program on page 38).

Battery Recharge Mode

 Once mains power is applied to the GXT4, the Battery Charger begins charging the batteries. 2.6.5 Frequency Converter Mode All models of the GXT4 are capable of frequency conversion. Frequency Conversion Mode can be selected using the configuration program. Allowable frequency operating modes include: • Auto Sensing - 50Hz or 60Hz – Bypass Enabled • Auto Sensing - 50Hz or 60Hz – Bypass Disabled • Frequency Converter - 50Hz – Bypass Disabled • Frequency Converter - 60Hz – Bypass Disabled NOTE: The default for all models of the Liebert GXT4 is “Auto Sensing - 50Hz or 60Hz – Bypass Enabled.” WARNING! Risk of electric shock. Can cause injury or death. Never touch the AC input receptacle while the UPS is operating. Voltage may still be present even when the AC input indicator is Off. 2.6.6 Active ECO Mode All Liebert GXT4 models can operate in Active ECO Mode. In this mode, the connected equipment is powered through the bypass path to increase efficiency, reducing the electrical costs. Active ECO mode keeps the rectifier and inverter operating, allowing the inverter to remain synchronized to bypass. This synchronization allows the transfer of the connected equipment to UPS inverter power
