NOTICE
Risk of damage or malfunction!
Waste inside the cabinet can cause damage or
malfunction.
If possible, do not cut cables inside the terminal
compartment. Retrieve any waste which
accidentally dropped into the cabinet.
Determining the cable length
1. Determine the required length of a cable
between the point of entry and the connection
point inside the cabinet.
2. Cut the cable to the required length before con-
nection.
See the applicable Mechanical drawings
for information on:
• Project-specific cable entry
• Distance between point of cable entry
and terminals
• Busbar and fastening hole dimensions
• Busbar designations
See the applicable Wiring diagrams for
information on:
• Conventions for cross-references and
device identification
• Transformer cables and motor cables
and their corresponding connections
Preparing the 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.
The grommets can be discarded if cables are
entered through the cabinet floor.
4. If necessary, remove the entry plate and push
the cable through the entry holes.
5. Prepare the cables as illustrated.

cable screen or shield are prepared
bonding with the metal enclosure of the cab-
inet.
