UPS Shutdown (via RS-232C)

When the UPS is operating from its internal batteries, a Shutdown order can be sent to the
UPS telling 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 RS232 screen.
