What to do if my Liebert UPS has reduced battery backup time?
Reduced battery backup time can occur for a few reasons. First, the batteries might not be fully charged. Keep the UPS plugged in continuously for at least 24 hours to recharge them. Second, the UPS could be overloaded. Check the load level indicator and reduce the load. Finally, the batteries may be old and unable to hold a full charge, and may need to be replaced.
What to do if the internal battery source is not available on my Liebert UPS?
If the internal battery source is not available, check the battery connection, then power down and reboot the UPS. This condition is also indicated by a continuous audible alarm.
What to do if the Liebert GXT3 fails to start when the On/Alarm Silence/Manual Battery Test button is pressed?
If the UPS doesn't start when you press the On/Alarm Silence/Manual Battery Test button, it might be short-circuited or overloaded. First, turn the UPS off. Then, disconnect all loads and make sure nothing is stuck in the output receptacles. Also, confirm that the connected loads aren't defective or shorted internally.
