Here is a related thread. This is a common fault on the SRT range. They mention a UPS firmware update MAY resolve the issue. http://forums.apc.com/spaces/5/smart-ups-symmetra-lx-rm/forums/general/11333/srt8kxli-power-sys-erro... 

Another method would be to perform the brain dead procedure which discharges the UPS's capacitors of all DC voltage. At this point the UPS will be turned off (including the output power to your load) and will be completely inoperable. 

This FAQ guides you on how to perform it for all other Smart UPS models but not the SURT / SRT. http://www.apc.com/au/en/faqs/FA156611/ (APC should be able to direct further on this)

I'm facing the same issue and already tried to upgrade the firmware and did the brain dead restart with no luck, Any suggestions
