2. Do you want to bring the cables out at the bottom of the module?

If so:

Start with terminal 20, and wire the

terminals in the following order:

terminal 20, 19, ... 1.

Starting at terminal 40 or 20, wire the

terminals alternately (i.e. terminals 39,

19, 38, 18 etc. down to terminals 21

and 1).

If not:

Start with terminal 1, and wire the

terminals in the following order: terminal

1, 2, ... 20.

Starting at terminal 1 or 21, wire the

terminals alternately (i.e. terminals 2, 22,

3, 23 etc. up to terminals 20 and 40).

3. Also tighten the screws of any terminals that are not wired.

4. – Thread the cable strain-relief assembly

into the front connector.

5. Pull the cable strain-relief assembly tight. Push the retainer on the strain-relief

assembly in to the left; this will improve utilization of the available space.
