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.
