Terminal block instruction

Start generator: when fault occurs in the normal power, this port will connect after delaying sometime.
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 connected into this port.
Remark: The normal earth wire and standby earth wire is just suitable for ATS of 3 phases.
