Replace Battery

Battery should be replaced. Contact Liebert Global Services at 800-543-2378 for assistance.

 

 

 

Before the end of discharging, battery under-voltage pre-warning should occur. After this pre-

Battery Low Pre-warning

warning, battery should have the capacity for 3 minutes discharging with full load. The time is

user configured from 3 to 60 minutes.

 

 

Shut down the load in time to prevent damage to equipment and data.

 

 

Battery End of Discharge

Inverter turned off due to low battery voltage.

Check the utility failure and try to recover it.

 

Mains Volt. Abnormal

Mains voltage exceeds the upper or lower limit and results in rectifier shutdown.

Check the input line-to-line voltage amplitude of rectifier.

 

Mains Undervoltage

Mains voltage is undervoltage 288V~384V line to line voltage with derated load.

Check the input line-to-line voltage amplitude of rectifier.

 

Mains Freq. Abnormal

Mains frequency is out of limit range and results in rectifier shutdown.

Check the rectifier’s input voltage frequency

 

Rectifier Fault

800-543-2378 for assistance.

 

 

Rectifier Overtemp.

The temperature of the heat sink is too high to keep the rectifier running.

The UPS can recover automatically. Check the environment and ventilation.

 

Charger Fault

The charger has a fault. Contact Liebert Global Services at 800-543-2378 for assistance.

 

 

Control Power 1 Fail

Control Power 1 has failed or has been lost. Contact Liebert Global Services at 800-543-2378

for assistance.

 

Mains Phase Reversed

Input phase sequence is inverse. Contact Liebert Global Services at 800-543-2378 for

assistance.
