What to do if my Eaton UPS buzzer sounds continuously and shows codes A80E, A810, or F808?

If your Eaton UPS buzzer is sounding continuously and the display shows code A80E, A810, or F808, it means the load applied to the UPS is too high. Reduce the load to within the threshold of 100% (or the user threshold in the case of code A80E). If the display shows a fault, remove the load and switch the UPS off and back on again.
