dual power switch with automatic manual power indicator FTSM ATS
FTSM series automatic transfer switch is mainly composed of power
transfer actuator, circuit breaker and controller. The dual power
switch has automatic, manual, power indicator, normal switch
indicator, ready switch indicator. This series of automatic
transfer switches are characterized by small size, long life, low
power consumption, light weight, stable operation, easy to use, etc

♦ 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.
