Sua1500 site wiring fault LED shouldn't be on

This was originally posted on APC forums on 3/3/2011

I just replaced the battery in an SUA1500 and no power comes out of the outlets, and the "site wiring fault" is on. I have checked the building wiring; no problems. Are there common items to check in the unit that could cause this? Does the circuit board need to be replaced? Can I just send in the circuit board without the entire unit? Can I just buy a new circuit board?
