12.4 Preparing the shield connections
The Touch Operator Panel and the modules in the slots are usually connected with D-Subminiature plug
connectors in accordance with DIN 41 652. Only use metal or metallised connector casings with a cable
clamp for strain relief fastened on one side of the connector. The clamping of the cable shield ensures an
optimum contact area and low impedance connection with the connector casing of the Touch Operator
Panel.
The following procedure is recommended for making the low-impedance connection for 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 tubing or insulation tape to cover the exposed cable sheath with the folded
back screen 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.

DIN 41 652), follow the instructions for the modules concerned.
