y You achieve the lowest possible effective antenna height by routing the cable directly on the ground
of the metallic rack.
y You should route all lines as close as possible to the conductors of the ground system to reduce the
effective loop area for magnetic coupling.
y When parallel-routing signal and control lines across power cables, the conductors must be at least
20 cm apart.
y Lines of different EMC categories should only cross at an angle of 90°.
y In the case of symmetrical signal transfer (e.g. differential amplifier inputs for the speed specified val-
ue), twist the conductors of each pair of wires together and twist the pairs of wires together.
y The converter to ground plate earth connection should be as short as possible (less than 30 cm).
Use large cross-sections (more than 10 mm²).
y Sources of interference such as fuses, transformers and chokes and modules that are sensitive to
interference like µPs, bus systems, etc. should be located at least 20 cm away from the converter
and its cabling.
y Avoid reserve loops on overlong cables.
