♦ Installation

When installing wiring, normal power N should be access to normal power supply circuit breaker QN, ready
power R should be access to ready power supply circuit breaker QR. When QN and QR is 4 poles circuit
breaker, wiring mode according to the wiring diagram, which QN and QR's 1, 3, 5 are three-phase ( A, B, C )
into line terminals, 2, 4, 6 are three-phase outgoing line terminals, 7 is zero line (N) into line terminal, 8 is
zero line outgoing line terminal. If the use of 3 poles circuit breaker, the normal power N's zero line (NN) and
ready power R's zero line (NR) must be respectively received on 3 poles special connection zero line terminal.
Specific see wiring diagram. Dual power transfer switch automatic controller's work power supply circuit breaker
QN and QR's into line terminal A and zero line N, in the automatic power switch installation, wiring process,
Do not let the local controller to forget to connect the signal line, touch off or short circuit and so on,
otherwise can not work.
