- Output 1 is dedicated to controlling the internal SSR.
- If 75A heat sink is selected below 1 Digital Input (6) will be factory set and fixed as
the SSR over temperature Digital Input.

ply
If the limit controller was ordered, the contactor will come
internally connected to output 4 on the limit module. The
contactor has external contacts available for daisy chaining to
other branch circuit components.
