Note
To ensure trouble-free operation without interference or disturbances, route the power cables
and signal lines separately. Interference, for example, will result in the device not behaving as
expected.
When connecting and routing power and signal cables, observe the instructions contained in
the "Electromagnetic compatibility" section.

5.2 Electromagnetic compatibility
The following fundamental information and guidelines facilitate compliance with the EMC
directives.
Note
We recommend that EMC is planned for the entire plant.
Cabinet installation
●
Connect painted or anodized metal components using contact washers or remove the
insulating layer.
● Use unpainted, de-oiled mounting plates.
● Establish a central connection between ground and the protective conductor system (PE
protective conductor).
Cable installation
● Cables that are subject to or sensitive to interference should be laid as far apart from each
other as possible.
● The distance between the electric power cable and signal cable should be > 20 cm. The
drive-specific information applies to power cables. You can find further information on power
cables under "Connecting power cables".
● When the cables are routed close to ground potential, the immunity to interference is
increased. For this reason, you are advised to lay these cables along edges and at ground
potential.
● Ground the reserve cores on at least one end.
