Smart-UPS X 3000 error

[Anonymous user]

We recently had a power cut which normally wouldn't be an issue as the UPS kicks in and keeps out servers up. However, on this occasion the UPS shut down immediately without warning and brought the servers down with it. 

Looking at the logs, it keeps flicking between "UPS: A battery charger fault exists."' and "UPS: A battery charger fault no longer exists." every couple of minutes.

Here are the measurements:

Is there anything I can do to fix this? Let me know if more information is needed.

Thanks!
