This read-write integer, in seconds, sets how long the ATS waits after receiving power before it turns on master power to its outlets, with -1 meaning never apply power automatically, 0 meaning immediately, and 1 to 300 a configurable delay. An admin staggers this delay to avoid every ATS in a row of racks pulling inrush current at the exact same instant after a facility-wide power restoration. For example, setting this to 60 seconds lets upstream circuit breakers settle for a minute before the ATS re-energizes its outlets after a utility outage.
