What to do if the power overload LED is on and Eaton 9PX 5000 UPS beeps continuously?
If the power requirements exceed the UPS capacity, remove some equipment from the 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.
Why is the bypass mode LED on my Eaton 9PX 5000?
An overload or a fault has occurred, or a command has been received and the UPS is in Bypass mode. This means your equipment is powered but not protected by the UPS. Check for one of the following alarms: overtemperature, overload or UPS failure.
How to fix an Eaton 9PX 5000 overtemperature issue?
If the UPS internal temperature is too high or a fan has failed, and if the UPS transferred to Bypass mode, the UPS 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, allow the UPS to cool, ensure the airflow around the UPS is not restricted and restart the UPS. If the condition continues to persist, contact your service representative.
What to do if the battery fault LED is on and Eaton 9PX 5000 UPS beeps continuously?
If the Eaton UPS battery test 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.
What to do if my Eaton UPS does not start?
The input source may not be connected correctly, so check the input connections. Alternatively, the Remote Power Off (RPO) switch may be active or the RPO connector is missing. If the UPS Status menu displays the 'Remote Power Off' notice, inactivate the RPO input.
Why doesn't my Eaton 9PX 5000 UPS provide the expected backup time?
The batteries may need charging or servicing. Apply utility power for 48 hours to charge the batteries. If the issue persists, contact your service representative.
What to do if no battery LED is on and Eaton 9PX 5000 UPS beeps 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 low LED is on and Eaton 9PX 5000 beeps every 3 seconds?
The UPS is in Battery mode, and the battery is running low. This warning is approximate, and the actual time to shutdown may vary significantly. Depending on the UPS load and number of Extended Battery Modules (EBMs), the 'Battery Low' warning may occur before the batteries reach 20% capacity.
Why is the battery mode LED on and Eaton 9PX 5000 beeping every 10 seconds?
A utility failure has occurred, and the UPS is in Battery mode. The UPS is powering the equipment with battery power; prepare your equipment for shutdown.
