7.2 Preparing the shield connections
The connections on the Touch Operator Panel and especially the communications card are mostly
implemented with D-subminiature connectors in accordance with DIN 41 652. Only use metal or metallised
connector casings with a cable clamp for strain relief fastened or clamped on one side of the connector. The
clamping of the cable shield ensures an optimum contact area and a 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 rubber grommet 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.
If plug connectors are used for communications cards (not D-subminiature plug
connectors to DIN 41 652), then follow the instructions in the relevant document
descriptions.
