3. Route the control cables as described in section Routing the control cables inside
the cabinet (page 59).
4. Connect the control cables as described in section Connecting control
cabling (page 59).
Grounding the outer shields of the control cables 360° at the cabinet entry
Ground the outer shields of all control cables 360° with the EMI conductive cushions
at the cabinet entry. The grounding principle is the same for top and bottom entry
cables. The figures show the bottom entry. The actual design details can vary.
1. If necessary, temporarily remove the shrouding in front of the cable entry.
2. Put the cables in sequence from the smallest to the largest. This will help to achieve
a good contact with the cushions.
3. Loosen the tightening bolts of the EMI conductive cushions and pull them apart.
4. Cut holes in the grommets and put the cables through the grommets.
5. Peel the insulation from the part of the cable that will be in contact with the EMI
conductive cushion.
6. Put the cables between the cushions and attach them with cable ties for strain
relief.
7. Move the cushions back together.
8. Tighten the bolts to make sure that the EMI conductive cushions press tightly
around the peeled part of the cables.
