UPS Shutdown (via RS-232C)

When the UPS is operating from its internal batteries, a 'shutdown' order can be sent to the
UPS instructing it to turn OFF after a user-specified amount of time. This function can
allow you to stop discharging the UPS batteries after an orderly system shutdown has
been completed. The UPS can be programmed to turn OFF up to 8 minutes after the
'shutdown' command is given. This command can be cancelled before the specified time
has elapsed by following the directions listed on the RS-232C screen.
