Preparing cables for EMC plates
Top or bottom cable entry
1. Remove the grommets.
2. To ensure proper sealing, cut along the marking
that corresponds to the cable diameter.
3. Slide the grommet onto the cable. The grom-
met must fit tightly to prevent water entering
the cabinet.
The grommets can be discarded if cables are
entered through the cabinet floor.
4. If necessary, remove the entry plate and pull the
cable through the entry holes.
5. Loosen the screws of the EMC cushion brackets
and push the cushions apart.
6. Remove the cable insulation at the point of
entry (6-10: 1) .
If the outer cable screen is non-conductive, cut
open the cable screen in the middle of the
stripped area
(6-10: 1) . To turn the conductive
side inside out, pull the cable screen ends over
the cable insulation
(6-10: 2) . Connect the
screens ends with a continuous conducting foil
(6-10: 3) .
7. Pull the cables through the EMC cushions.
8. Push the cushions together so they fit tightly
around the bare screen and tighten the screws.
