1.6 UPS States and Operating Modes

NOTE: See LEDIndicators on page 31, fordescription of the run-indicatorand alarm-indicatorLEDs mentioned in this section.

1.6.1 Normal Mode

When utility power is normal, Normal mode employs the rectifier and inverter to provide voltageand frequency-stabilized power to the load. The charger charges the battery in normal mode. On the frontpanel display, the run-indicator (green) is On, the alarm indicator is OFF, and the buzzer is silent.

1.6.2 Bypass Mode

Bypass mode supplies power to the load from the bypass source (utility power) if an overload or fault occurs during normal operation. On the front-panel display, the run indicator (green) is On, the alarm indicator (yellow) is On, and the buzzer beeps once each seconds. The LCD "Current" screen displays "On Bypass."

NOTE: If utilitypowerfails orif the utilityvoltage goes outside of the permissible range during bypassmode operation, the UPS shuts down and no output is supplied to the load.

1.6.3 Battery Mode

Battery mode supplies battery power to the load if utility power fails or if the utility voltage goes outside of the permissible range. On the front-panel display, the run indicator (green) is On, the alarm indicator (yellow) is On, and the buzzer beeps once each second. The LCD "Current" screen displays "On Battery."

NOTE: The batteries are fully-charged before shipment. However, transportation and storage inevitablycause some loss of capacity. To ensure adequate back-up time, charge the batteries foratleast 8 hours before first start-up.

NOTE: If utilitypowerfails and the batteries are charged, you maycold-start the UPS in batterymode and use batterypowerto extend system availabilityfora time.

NOTE: Powering-off the UPS when it is in batterymode results in loss of output powerto the connected load.

1.6.4 Frequency Converter Mode

All models of the GXT5 are capable of frequency conversion. Frequency Conversion Mode can be selected using the configuration program. Allowable frequency operating modes include:

•Auto Sensing - 50 Hzor 60Hz – Bypass Enabled

•Auto Sensing - 50 Hzor 60Hz – Bypass Disabled

•Frequency Converter - 50 Hz – Bypass Disabled

•Frequency Converter - 60Hz – Bypass Disabled

NOTE: The default forallmodels of the Liebert®GXT5is “Auto Sensing - 50Hz or60Hz – Bypass Enabled.”

1 GXT5 Description	13

1.6.5 ECO Mode

The energy-saving ECO mode reduces power consumption by powering the load via bypass if the bypass voltage is normal or by powering the load via the inverter when the bypass voltage is abnormal. You can use ECO mode to power equipment that is not sensitive to power-grid quality to via bypass and reduce power consumption.

NOTE: During Eco mode, if a bypass-failure orabnormal-bypass-voltage notification appears when the output is not overloaded, the UPS willtransferto NormalMode. However, if a notification showing bypass failure orabnormalbypass voltage appears when the output is overloaded, the UPS willshut down the bypass.
