Cables without interference suppression must be laid at
a distance of at least 200mm from the mains input side
of the lter so that no interference can be coupled into
the cables.

3.2 Switch cabinet layout
The positioning of the components in the switch cabinet has a signicant effect on the
trouble-free system and machine function. You should take into account the following
points in your planning:
y Evaluate the assemblies used in relation to EMC.
y Divide the switch cabinet into zones with different power and interference levels.
y For devices susceptible to interference, maintain a distance of at least 200mm
from the following components:
− Drive controller
− Input and output chokes, transformers
− Mains, motor, DC power supply and braking resistor cables (even if shielded)
− Relay and contactors (even if interference-suppressed)
y For small distances use separators for shielding; fasten the separators directly
and conductively to the backing plate.
y If a motor contactor or motor choke is used, the component should be
positioned directly at the drive controller.
y Do not use uorescent lamps in switch cabinets, as they emit high-frequency
interference.
y Fit contactors, relays, solenoid valves, switched inductors and capacitors with
suppressors.
y The mains lter must be mounted on the backing plate as close as possible to
the feed point and with large surface area contact. The backing plate must be
connected to the central earthing point with a low-impedance connection.
No unltered cables are allowed to be laid on the mains input side of the lter so
that no interference can be coupled into the cables.
