Laying cables outside of control cabinets

All cable ducts should be constructed of electrically conducting material and connected to functional
ground at regular intervals. Bus cables should not be subject to mechanical loads which exceed the
manufacturer's specifications. If this cannot be avoided, additional protective measures should be taken,
e.g. by laying the cables in a steel pipe or rugged metal duct. The pipe or duct should then be grounded at
regular intervals and protected against corrosion.
