Connecting cable shields

Using shielded cables
The following options are available for the shield connection when using shielded cables:
• A shield connection using a shielding bus supplied separately
• Shield contact with shield contact element at the top of the SIMATIC Drive Controller
enclosure.
Using a shielding bus
Proceed as follows to use a shield bus:
1. Strip the cable shielding.
2. Attach the shield to a grounded shield bus after the point where the cable enters the
cabinet.
3. Run the shielded cable as far as the module but do not establish a connection to the shield
there.
Using a shield contact on the SIMATIC Drive Controller
1. Loosen the shield contact bracket ① far enough to create space under the bracket (M3
screw, Torx T10).
2. Strip the cable shielding and insert the cable.
3. Attach the retaining bracket so that the cable shield and cable ② are pressed against the
shield support by the retaining bracket (tightening torque 0.8 Nm or 7.1 lbf in).
