Note
When the front connector is put in its operating position, a front connector coding engages in
the front connector. The front connector then only fits this type of module.
4.3.4 Connecting shielded cables via a shield connecting element
Introduction
This section tells you how to connect the shield of shielded signal lines to ground via a shield
connection element. The connection to ground is achieved by direct contact between the shield
connection element and the mounting rail.
Application
You can do the following easily with the shield connection element:
● Connect all shielded cables of ET 200PA SMART or modules from the S7-300 series of
modules to ground
● Connect the bus cable to ground.
Design of the shield connection element
The shield connection element consists of the following parts:
● A fixing bracket with 2 threaded bolts for fixing to the mounting rail
(6ES7390‑5AA00‑0AA0)
● The shield connection clamps
Depending on the cable cross-sections used, you must use the following shield connection
clamp:
