1. Exposing the screening: Strip off the plastic outer sheath over a length of 30-
40 mm in the area of the connecting terminals for cable ties.
2. Wrap the tracer tightly about 5 times around the extremity of the screen (Fig.
4.9).
3. Contact the screen with the housing: Use a cable tie to secure the cable sec-
tion over a large area to the intended contact surface with the screening
exposed (Fig. 4.10).
Tip:
Secure several small-diameter cables together in a bundle.
