Why is the No Battery LED on and Eaton Power Supply beeping continuously?
If the No Battery LED is on and the Eaton Power Supply is beeping continuously, the batteries are disconnected. Verify that all batteries are properly connected. If the condition persists, contact your service representative.
What does it mean when the Battery Fault LED is on and Eaton Power Supply beeps continuously?
If the Battery Fault LED is on and the Eaton Power Supply beeps continuously, the battery test has failed due to bad or disconnected batteries, or the battery minimum voltage is reached in ABM cycling mode. Verify that all batteries are properly connected. Start a new battery test; if the condition persists, contact your service representative.
Why won't my Eaton Power Supply start?
The Eaton Power Supply might not start because the input source is not connected correctly. Check the input connections.

How to fix an Eaton Power Supply with the Overtemperature LED on and beeping every 3 seconds?
If the UPS Overtemperature LED is on and it beeps every 3 seconds, the UPS internal temperature is too high or a fan has failed. If the UPS transferred to Bypass mode, it will return to normal operation when the temperature drops 5°C below the warning level. If the condition persists, shut down the UPS. Clear vents and remove any heat sources, ensure airflow is not restricted, allow the UPS to cool, and then restart it. If the condition continues to persist, contact your service representative.
Why doesn't my Eaton Power Supply provide the expected backup time?
If the Eaton Power Supply isn't providing the expected backup time, the batteries may need charging or servicing. Apply utility power for 48 hours to charge the batteries. If the issue continues, contact your service representative.
Why is the Bypass Mode LED on for my Eaton Power Supply?
The Bypass Mode LED is on because an overload or fault has occurred, or a command has been received, and the Eaton Power Supply is in Bypass mode. This means your equipment is powered but not protected by the UPS. Check for alarms indicating overtemperature, overload, or UPS failure.
What to do if the Battery Mode LED is on and Eaton Power Supply beeps every 10 seconds?
If the Battery Mode LED is illuminated and the Eaton Power Supply beeps every 10 seconds, it means a utility failure has occurred, and the UPS is operating in Battery mode. You should prepare your equipment for shutdown, as the UPS is currently powering it with battery power.
What to do if the power overload LED is on and the Eaton UPS beeps continuously?
If the power requirements exceed the UPS capacity, remove some equipment from the Eaton UPS. The UPS will continue to operate, but may switch to Bypass mode or shut down if the load increases. The alarm resets when the condition becomes inactive.
