Make the connections according to the application. Keep the signal wire pairs twisted as near to the terminals as possible

to prevent inductive coupling.

Remove the rubber grommets from the cable entry for the cables to be connected. Attach cable conduits to the empty

cable entry holes. Slide the cables through the cable conduits.

Ground the shield at one end of the cable only. If you ground the shield at the source of the signal, do not ground it at

the SCR terminal.

Tie all control cables to the provided cable tie mounts.
