Start generator: when fault occurs in the normal power, this port will connect after delaying some time.
□ Normal close: When the normal power of ATS is in closing state, closing signal without power is output from this port.
□ Standby close: When the standby power of ATS is in closing state, closing signal without power is output from this port.
□ Normal earth wire: When ATS are 3 phases, the normal earth wire is connected into this port.
□ Standby earth wire: When ATS are 3 phases, the standby earth wire is Remark: The normal earth wire and standby earth wire is just suitable for ATS of 3 phases.
