1、As the max output capacity of bypass relay K1 is 5A
only,it is unable to control high-power AC contactor
directly，for AC contactors of 167A above，intermediate
relay is recommended；
2、When wiring in this way，it starts when KA1 closes，
stops when KA1 opens；
3、Three-wire control mode can be used，which could leave
out the KA1 intermediate relay ；
4、KH thermal relay can be omitted（soft starter itself
already has overload protection function）；
5、Terminal number accords with the description of control
terminals.
