Protective conductor connection and shield support

It is always advisable to shield the digital I/O wiring.
The following diagrams show typical Weidmüller shield connection terminals for the shield
supports.

If the shielding procedures described and the specified cable lengths are not observed, the
machine may not operate properly.
NOTICE
Only use screws with a permissible insertion depth of 4 - 6 mm.
The TM15 enclosure is connected to the ground terminal of the module supply (terminal
X524). If the ground terminal is actually grounded, then the enclosure is also grounded. An
additional ground connection using the M4 screw is especially necessary if high equipotential
bonding currents can flow (e.g. through the cable shield).
