Special precautions providing high noise immunity
Inductors controlled by your programmable controller (e.g. contactors and
relays) do not normally require additional snubber networks or suppressors
as the respective modules have been provided with the required
components.
Snubber networks must only be connected to inductors when output
circuits can be disabled by means of additional contacts (e.g. relay
contacts). In this case the integrated suppressors on the module are also
disabled.
You can connect diodes to suppress back-emc, varistors or RC-networks
to the inductors.

Every cubicle must be provided with a power outlet for the PU. These
outlets must be wired to the distribution system, which is also used to
connect the neutral conductor for the cubicle.
The cubicle illumination should consist of incandescent lights, e.g.
LINESTRA-lamps. Avoid using fluorescent lamps as these lamps can
cause interference.
If you can not avoid using fluorescent lamps you should implement the
steps outlined in the following figure.
