6.8 Connecting shielded cables to the shielding contact element
Application
Using the shielding contact element, you can easily ground all shielded cables of
S7 modules, due to the direct contact of the shielding contact element to the profile
rail.
Design of the shielding contact element
The shielding contact element consists of:
• a bracket for screw-mounting (with two screws) it onto the profile 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:
Table 6-9 Specifying the shielding diameter for shielding terminals
Cable with shielding diameter Shielding terminal Order No.
2 cables each one with a shielding diameter of 2 to 6
mm
6ES7 390-5AB00-0AA0
1 cable with a shielding diameter of 3 to 8 mm 6ES7 390-5BA00-0AA0
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.
Mounting the shielding contact element
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 the
shielding terminal at this position onto edge "a" of the bracket (see the Figure
below). Push the shield terminal down and swing it into the desired position.
The two rows of the shielding contact element allow you install a maximum of
4 shielding terminals.
