CHAPTER 6 – ELECTRICAL INSTALLATION 98
Preparing cables for EMC plates
The orientation of the EMC plates is the same for
top and bottom cable entry: the sealing grommets
face always upwards.
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.
4. The grommets can be discarded if cables are
entered through the cabinet floor.
5. If necessary, remove the entry plate and push
the cable through the entry holes.
6. Prepare the cables as illustrated in 6-5 .
- (A) illustrates how cables with an outer cable
screen or shield are prepared
for EMC bond-
ing with the metal enclosure of the cabinet.
- (B) illustrates how cables without an outer
screen or shield are prepared .
