Secure the shielding so that as much of the braided shield as possible is held
underneath the clamp of the shield connection.
Make sure there is good contact between the connector and base.
Do not damage or squeeze the wires.
When connecting the shielding, observe the specifications for the connector wiring.
Always connect analog sensors and actuators with shielded, twisted pair cables.
Connect the shielding via the Inline connector with shield connection (see "Connecting
shielded cables using an Inline shield connector" on page 10-2).
As a rule, shielding must only be connected directly to the PE potential on one side. This
is to prevent any occurrence of voltage equalization currents via the shielding.
If necessary, integrate the shielding concept for analog I/O cables into the system
concept, for example, it is useful to use a central FE shield connection at the control
cabinet entry.
