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

Damage or faulty operation due to incorrect shielding and impermissible cable lengths

If the correct shielding procedures and the permissible cable lengths are not observed, the

machine can be damaged or may malfunction.

• Only use shielded cables.

• Do not exceed the cable lengths stated in the technical data.

Only use screws with a permissible mounting 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 potential

bonding currents can flow (e.g. through the cable shield).
