8.1.4.3 EMC measures
For interference-free operation of the USS, it is absolutely necessary
that the following measures are carried out:
Shielding is necessary for damping magnetic, electrical and
electromagnetic interference fields. Interference currents are
discharged to earth by the shield braiding via the housing earth.
The bus cables must be twisted and shielded and are to be routed
separately from power cables, the minimum clearance being 20 cm.
The shield must be connected through the largest possible surface area
on both sides, i.e. the shield of the bus cable between 2 converters
must be connected to the converter housing at both ends. The same
applies to the shield of the bus cable between master and converter.
If bus and power cables intersect, they must do so at an angle of 90 °.
With regard to the bus cable, the shield must not be exposed in the
bus connector. Shielding is provided by the shield clamps (Compact
type units) or shield clamps and cable ties (chassis type units) at the
converter housing. How to use the shield clamps is shown in the
following illustration. It must be ensured that the solid copper core is
not damaged when the insulation is removed from the ends of the
conductors.
It must also be ensured that the shield of every bus cable is
connected where the cable enters the cabinet as well as at the
converter housing!
