5.3.2 Preparation of cables with D-Sub connector

The preparation of bus cables is an essential factor in ensuring reliable operation and electromagnetic

compatibility (EMC).

Wiring requirements

# The cables must be shielded.

# The cable shield must be made from a copper braid.

# The cable shield must make a low impedance connection with the connector casing over a large

contact area. This is achieved by:

# Use of metal or metallized connector casings with a cable clamp for strain relief.

# The cable clamp must be screwed securely to the connector.

Connecting the cable

shield

1 Strip the cable end so that approx. 3 cm of the shield braid is exposed.

2 Fold back the shield braid over the cable shield.

3 Fit approx. 3 cm of heat shrinkable tubing over the folded back end of the shield braid or use a

rubber grommet.

# 5…8 mm of the shield braid must be exposed at the cable end.

# The folded back shield braid end must be covered by the heat shrinkable tubing or by the

rubber grommet.

4 Fit the D-Sub connector to the cable end:

# The exposed metal shield braid must be clamped to the connector casing with the cable clamp.
