Bypass Contactor Wiring
The GS Series Soft Starters require bypass contactors, whereas for the GW Series Soft Starters this is optional. Please see wiring as indicated below (Use Bypass Contactor with ~250VAC Coil):
*If there is no Neutral Line available, it is possible (but not ideal), to connect Terminal 1 to another Line Phase and use a Bypass Contactor with a ~400V Coil.
