AC Input Disconnected after v497 update on Multiplus-II 12/3000/120-50 2x120

I updated my Multiplus-II to firmware v497 (from v494) last night. All operated ok through today until about 3pm. Since that time the Multiplus refuses to connect to incoming AC. It will retry every few minutes but immediately fails. I am not sure this is related to the update but it is coincidental that this is the first time it has ever experienced this behavior.

It is not the firmware update -- purely coincidental. I found an AC wiring connection problem that was causing current fluctuations and making the Multiplus-II reject the connection.
