y You achieve the smallest possible effective antenna height by laying the cable directly on the ground
of the metallic rack
y You should lay all cables as close as possible to the conductors of the ground system to reduce the
effective loop area for magnetic coupling.
y
When laying signal and control cables in parallel across power cables, maintain a minimum distance
of 20 cm between the conductors.
y
Cables of different EMC categories should only cross at an angle of 90°.
y
For symmetrical signal transmission (e.g. differential amplifier inputs for the speed setpoint), twist
the conductors of each pair together and twist the pairs of wires together.
y
The connection between converter and ground plate should be as short as possible (< 30 cm). Use
large cross-sections (>10 mm
2
).
y
Sources of noise such as fuses, transformers, chokes and noise-sensitive modules such as
microprocessors, bus systems, etc. should be located at least 20 cm away from the converter and
its cabling.
y
Avoid reserve loops on long cables.
y
The grounding of reserve wires in cables is mandatory (additional screening, avoidance of capaci-
tively coupled, hazardous contact voltages).
