The delay command ('N') was sent successfully, so the UPS is receiving commands.

Is the unit on line power at this point? I don't think we know the command needed to power off the UPS when it is not running on battery (the 'G' command seems to be "wait for power to return"). I suspect we could emulate it with the watchdog, but that will require a fair amount of testing to make sure we understand the timer.
