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.
What to do if Fault and Bypass indicators and all LED segments of battery level indicator are illuminated in my Liebert UPS?
If the Fault and Bypass indicators and all LED segments of the battery level indicator are illuminated, this means that the UPS is overloaded or the load is faulty. Check the load level indicator and remove any non-essential loads. Recalculate the load and reduce the number of devices connected to the UPS. Also, check the connected loads for any faults.
What does it mean if the AC input indicator is flashing on my Liebert GXT3?
A flashing AC input indicator means the UPS has detected a line-to-neutral reversal or a loss of proper grounding. This is only active when power is first applied to the input and the UPS will not start in standby status. Once the UPS is running, the AC input indicator will flash, unless the input wiring is correctly changed. It is suggested to contact a qualified electrician to verify the site wiring.
What to do if the Liebert GXT3 Fault and Bypass indicators and diagnostic A indicator are illuminated?
If the Fault and Bypass indicators and diagnostic A indicator are lit, the UPS shut down because of an overtemperature condition, and the load is now on bypass power. Ensure the UPS isn't overloaded, that the ventilation holes aren't blocked, and that the room temperature isn't too high. Wait 30 minutes for the UPS to cool down, then restart it.
Why is the battery indicator flashing on my Liebert GXT3?
A flashing battery indicator means the battery source is not available. Check the battery connections, completely power down the UPS, and then restart it. Note that if the battery circuit opens while the UPS is running, it will be detected during the next battery test.
What does it mean when the bypass indicator is flashing on my Liebert UPS?
A flashing bypass indicator means that the bypass is disabled because the voltage or frequency is outside acceptable limits. The AC input powers the PFC input and serves as the bypass source. If the AC is present but the voltage or frequency exceeds the acceptable range for safe operation with a load, the bypass will be disabled and this indicator will flash, indicating that the bypass is unavailable.
What to do if the Fault indicator and diagnostic A and C indicators are illuminated on my Liebert UPS?
If the Fault indicator and diagnostic A and C indicators are illuminated, the UPS failed the battery test and the batteries may need replacing.
What does it mean if the Liebert UPS Fault and Bypass indicators and diagnostic C and E indicators are illuminated?
If the Fault and Bypass indicators and diagnostic C and E indicators are illuminated, the UPS was shut down by a command from the communications port(s). If this was inadvertent, ensure the communication cable used is correct for your system.
