Example: Integration of analog shielding in a concept with central equipotential

bonding at the control cabinet entry

Figure 11-11 Integration of analog shielding in a concept with central equipotential

bonding at the control cabinet entry

1 Lead the analog cable into the Inline connector making sure to maintain the cable in-

sulation.

2 Use shielded twisted pair cables.

3 Connect the strain relief directly to PE potential.

Connect the shield for the entire analog transmission path to PE potential at just one

point. In the example above, this point is the jumpering level (C).

4 Lead the sensor cable into the sensor making sure to maintain the cable insulation.

NOTE: Possible malfunctions

When integrating the shielding of analog I/O cables in an equipotential bonding

concept, make sure that direct connection to the PE potential is only made at one

point (e.g., at the central grounding point of the jumpering level).
