With the shielding contact element, you can easily connect all shielded cables of
S7 modules to ground by means of a mounting rail.

The shielding contact element consists of:
• a bracket for screw-mounting (with two screws) it onto the rail
(Order No.: 6ES5 390-5AA00-0AA0) and
• the shielding terminals.
You must use the following shielding terminals, depending on the shielding
diameter of your cables:

1 cable with a shielding diameter of 4 to 13 mm 6ES7 390-5CA00-0AA0
The shielding contact element width is 80 mm. It provides termination space in two
rows, each one for 4 shielding terminals.

1. Push the two screw bolts of the fixing bracket into the guide on the underside of
the rail.
2. Position the bracket underneath the modules whose shielded cables are to be
terminated.
3. Screw-tighten the bracket onto the rail.
4. The shielding terminal is equipped with a slotted web underneath. Place this
part of the shielding terminal on the edge of the mounting bracket. Now push
the shielding terminal down and pivot it into the desired position.
