Setting this object to a nonzero value schedules the UPS output to turn off after that many seconds, while setting it to 0 attempts to abort a pending shutdown already in progress. It gives an admin remote, timed control over shutting down the load the UPS powers, for example to coordinate with server shutdown scripts. For example, setting upsControlOutputOffDelay to 300 gives connected servers five minutes to finish shutting down before the UPS cuts output power.
