3.3.1 Preparing the cables with the SUB-D plug
The design of the wiring is an essential factor for reliable operation and elec-
tromagnetic compatibility (EMC).
3.3.1.1 Wiring requirements
• The cables must be screened.
• The cable screen must consist of a copper braid.
• This cable screen must be terminated to the connector shell with a low-
impedance bond across a large area.
3.3.1.2 Connecting the cable screen
Figure 4: Connecting the cable screen
▶ 1. Insulate the cable end so that approx. 3 cm of screen braid is exposed
① .
▶ 2. Fold back the screen braid over the cable sheath ② .
▶ 3. Attach heat-shrink tubing approx. 3 cm in length over the folded screen
braid or use a rubber grommet.
• 5…8 mm of the screen braid must be exposed at the cable end.
• The folded screen braid end must be covered by the heat-shrink tub-
ing or the rubber grommet
③ .
▶ 4. Fit the SUB-D plug to the cable end:
• The exposed metal screen braid must be clamped to the connector
casing with the cable clamp.
