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).

Lead the analog cable into the Inline connector making sure to maintain the cable
insulation.
Use shielded twisted pair cables.
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).
Lead the sensor cable into the sensor making sure to maintain the cable insulation.
