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.
