4.3 Shield connection
Only use metal or metallised connector casings with a cable clamp for cable anchoring fastened on one side
of the connector. This ensures an optimum contact area and low impedance connection with the connector
casing.
The following procedure is recommended for connecting the cable shield:
1. Strip the cable.
2. Shorten the exposed shield braid by approx. 3 cm.
3. Turn back the braid over the cable sheath.
4. Use a heat shrinkable tube or insulation tape to cover the exposed cable sheath with the folded
back shield braid so that 5 to 8 mm of exposed cable shield is left at the sheath end and is cleanly
covered at the back.
5. Fit the connector.
6. The cable is then fastened at the exposed shield braid and the cable sheath below it directly underneath
the cable clamp strap of the connector casing.
