If filters are required, mount them close to the controller and keep the
supply wiring as short as practical. Attempt to layout the wiring in a way
that minimizes cross coupling between filtered and non-filtered
conductors. This means avoiding running wires from the output of a filter
close to those connected to its input. Where you wish to minimize the
cross coupling between wires avoid running them side-by-side one
another, if they must cross, cross them at 90° to each other. Keep wiring
supported and close to cabinet metalwork.

Cables may require the use of ferrite core suppressors.
Some installations may require that you take additional EMC measures.
To further increase product immunity and reduce product emissions,
you may add clip-on ferrite absorbers to all cables. Parker Hannifin
recommends ferrites with at least 200 ohm impedance at 100 MHz,
such as the following:
Steward Ferrite
Part number 28A2024
Fair-Rite
Part number 0443164151
(These ferrites are available from Parker Hannifin, part number 47-015956-01)
Ferrite absorbers also are recommended for cable runs longer than 5
meters.

Take care that the power supply providing the pull-up voltage to the
controller’s high-speed inputs and outputs is free from electrical noise.
Short-Duration transient events, such as those caused by electrical
relays, can induce sufficient voltage disturbance on unfiltered DC
power lines to affect I/O performance. One method of reducing the
amplitude of transient disturbances on DC power lines is to add ferrite
suppressors (3 turns) to the conductors as shown in Figure 37 on
page 156.

Your Installation may require additional EMC installation hardware (as
shown in illustrations).
