Laying cables inside of buildings
Laying cables within control cabinets
If a repeater is installed within a control cabinet, the cable shield of the
incoming bus cable should be electrically connected to a grounding rail as
close as possible to the cable lead through using a shield grounding
clamp or similar. The cable shield should continue within the cabinet to
the fieldbus device and be connected there in accordance with the
manufacturer’s instructions.
Laying cables outside of control cabinets
PROFIBUS cables and cables for DC and AC voltages > 400 V
(unscreened), areas with explosion hazard and telephone cables
separate cable runs spaced at least 10 cm apart. 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.
