[AFMUG] APC Site Wiring Fault

[Nate Burke]

Our temps are Below 0 now, and one of my APC UPS's at a site keeps 
sending an alert 'Site wiring fault'  then clears a few minutes later.  
The APC Knowledge base lists off some various reasons, Overloaded 
Neutral, Disconnected Groud, but basically says call an electrician.  Is 
this something I should be worried about, or just figure that there is a 
loose ground connection in the cold.  This is at a grain facility which 
is new within the last year, so it's not like it's old electric.  He 
installed our own breaker back at the panel, but we are sharing a neutral.

Anyone else had to troubleshoot this before, or just don't worry about 
it.  The UPS is still self testing just fine.
