Planning
Install the equipotential bonding as close as possible to
the PROFINET cable.
Connect all individual parts of the cable raceways
(metal) with each other. Use special-purpose
connecting material to do this. Make sure to use
the same material for the cable raceways and the
connecting pieces. Appropriate material is available
from manufacturers of cableways.
Connect the metallic cableways as often as possible
with the equipotential bonding.
Use expansion or articulated joints for exible earthing
strips. Earthing strips are usually available from cable
manufacturers.
Fibre-optic cables are used for the connection between
various buildings or building sections. Owing to their
insensitivity to EMC loads, no equipotential bonding
is required for these bre-optic cables, provided they
contain no metal.
