UPS: Bypass not in range ; low voltage.

This question was originally posted by Vinayak on APC forums on 2/16/2020

Apologies in advance if this thread has been discussed and solved before.

Our Smart-UPS SRT 10000 has been giving the error since a power outage where it was using battery power for about 10 minutes went back online when the power came back. We have been getting this alert continuously for about 24 hours now.

Critical - UPS: Bypass not in range ; low voltage.

We checked with building electricians who haven't been able to find any fault with the input.


Any suggestions will be much appreciated.
