Connecting Cable Shields - Siemens SIMATIC ET 200S Manual

Connecting cable shields

We recommend you use the shield contact to connect cable shields (in the case of
analog electronic modules, the 1COUNT 24V/100kHz electronic module and the
1SSI electronic module, for example).
1. Remove the insulation material from the area around the shield terminal, and
clamp the cable shield in the shield terminal (above the conductor rail). The
shield terminal is suitable for one cable with a max. ∅ of 8 mm or two cables
with a max. ∅ of 4 mm each.
2. Tighten the shield terminal (approximately 0.5 Nm)
3. Repeat steps 1 and 2 if you want to connect additional cable shields.
4. Strip the insulation from the ground wire (from 6 mm to 25 mm
the ground connection terminal (under the conductor rail). Tighten the ground
connection terminal (2 Nm to 2.5 Nm).
5. Attach the other end to the ground bus.

Note
To stabilize the shield contact, you must mount and screw in at least one shield
terminal over the shield contact element.
