Hello,

we are using an APC SURT6000XLI with 4 extra battery packs SURT192XLBP. A few years it was working really fine. But now I have found some entries in the logs I do not understand, maybe somebody can tell me, what to do:

03:55:15  UPS: In bypass in response to an internal hardware fault.

03:55:17  UPS: An inverter fault exists.

03:55:20  UPS: Refused a self-test; UPS is overloaded.

The batteries are ~ 6 years old. Is the reason for this error messages, that I have to replace them?

Greetings and thank you very much!

Hi Digger - 

These faults indicate a possible hardware fault with the UPS itself, not the batteries. Did the faults clear by themselves? If not, you can try clearing them with e "Brain Dead" procedure. To do this:

• Turn Off the UPS
• Unplug the UPS from Utility power
• Disconnect all batteries internal and external
• Reconnect batteries, reconnect utility power, and turn UPS back on

If this does not clear your error you likely have a hardware fault. I would contact your local tech support team for further assistance.

Thanks!

Liam
