in separate cable ducts.
Ideally, the motor power cables should exit the control cabinet at a distance
of at least d3 = 200 mm from the (filtered) power supply cable.

Ground connections
Housing and mounting plate
With the appropriate ground connections, it is possible to avoid the emission
of interference, because interference is discharged to ground on the shortest
possible way.
Ground connections of the metal housings of EMC-critical components (such
as filters, devices of the drive system, connection points of the cable shields,
devices with microprocessor and switching power supply units) have to be
well contacted over a large surface area. This also applies to all screw
connections between mounting plate and control cabinet wall and to
mounting a ground bar to the mounting plate.
The best solution is to use a zinc-coated mounting plate. Compared to a
varnished plate, the connections in this case have a good long-time stability.
Connecting elements
For varnished mounting plates, always use screw connections with tooth lock
washers and zinc-coated, tinned screws as connecting elements. At the
connection points, remove the varnish so that there is safe electrical contact
