Possible consequences:
Property damage or operational malfunction
Protective measures:
Avoid compensation currents via the PROFIBUS cable shield:
ƒ
Connect all PROFIBUS stations with a 16 mm
2
cable via the PE bolts.
ƒ
Lay this cable in parallel to the bus cable.
ƒ
Use copper braid cable to establish a conductive connection between the PE
bolts and the mounting surface.
