High compensation currents
High compensating currents can flow via the PROFIBUS cable shield.
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 FE bolts.
ƒ Lay this cable in parallel to the bus cable.
ƒ Use copper braid cable to establish a conductive connection between the FE
bolts and the mounting surface.
