Note:
1. When wiring, commonly used power N should enforce access common power supply circuit breaker QN standby power R should enforce access the standby power supply circuit breaker QR when QN quadrupole is broken and chronological, connection mode according to the wiring diagram, including QN and QR 1, 3, 5 for threephase terminal, 2, 4, 6, for the threephase line end, 7 zero line into the terminal, eight is zero line end of line. If the circuit breaker is a threelevel circuit breaker, the neutral NN of the common power supply (N) and the neutral NR of the standby power supply (R) must be connected to the neutral terminal of the threepole dedicated wiring at the same time.
2. The working power of the double power switch automatic controller is taken from the incoming terminal and zero line of the new circuit breaker QN and QR. During the installation and wiring of automatic power switch, do not shake off, break or short circuit the original control line connected to the incoming line.
