The delay after going On Battery until the Receptacle is automatically turned Off. A value of -1 means that this Output should never be turned Off automatically, but must be turned Off only by command. Values from 0 to 30 are valid, but probably innappropriate. The AutoOffDelay can be used to prioritize loads in the event of a prolonged power outage; less critical loads will turn off earlier to extend battery time for the more critical loads. If the utility power is restored before the AutoOff delay counts down to 0 on an outlet, that outlet will not turn Off.
