Note:
1. There are two wiring ways to control the soft starter to start and stop.
They are three-line and two-line wiring. ( See and in the figure above ).
Connect according the figure free stop
Connect according the figure soft stop
2. In the A series product, there is no terminals U1,V1,W1. Because there is inner
bypass contactor.
