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 floor.
If necessary, remove the entry plate and pull the
cables through the entry holes.

6.10.3 Connecting the cables
IOEC modules
Connect the cables for digital and analog input and
output signals to the IOEC modules.
Conductors
• If a twisted pair cable is used, leave the
unshielded cable ends twisted until they reach
the terminals.
• Leave unshielded conductor ends as short as
possible (not longer than 50 mm).
Cable shields
1. Connect the shield of serial communications
cables to the fieldbus adapter.
2. Connect the overall shield and the individual
shields of the encoder cable to the separate
shield grounding bracket (3). Do not connect
the shields directly to the encoder adapter (1).
To accommodate encoder cables of different
diameters, ground clamps
are supplied.
