8. Connect the twisted cable shields to the grounding terminals.
9. Connect the conductors of the input and motor cables. Tighten the screws.
10. Install the control cable grounding shelf.
11. Units with option +D150: Connect the conductors of the brake resistor cable to the
R+ and R- terminals.
12. Reinstall the shroud on the power terminals.
13. Reinstall the EMC shroud separating the input and output cabling (if removed in
step 3).
14. Secure the cables outside the unit mechanically.
15. Ground the motor cable shield at the motor end. For minimal interference, make a
360-degree grounding at the cable lead-through, or keep the pig tail short.
Connect the control cables
See figure F.
1. Cut adequate holes into the rubber grommets and slide the grommets onto the
cables. Slide the cables through the holes of the bottom plate and attach the
grommets to the holes.
2. Strip the cable ends and cut to suitable length (note the extra length of the
grounding conductors).
3. Ground the outer shields of all control cables 360 degrees at a grounding clamp in
the cable entry box.
4. Ground the pair-cable shields to a grounding clamp below the control board.
Leave the other end of the shields unconnected or ground them indirectly via a
high-frequency capacitor with a few nanofarads, eg, 3.3 nF / 630 V.
5. Connect the conductors to the appropriate terminals of the control board (see
page 12).
6. Wire the optional modules if included in the delivery.
7. Reinstall the front cover.
