● For copper, at least 6 mm²
●
For aluminum, at least 16 mm²
● For steel, at least 50 mm²
Note
If this is not observed, high leakage currents can flow through the cable. This can result
in a fault in the data connection or device defects.
Due to the maximum length of 100 m for PROFIBUS copper cable at 12 Mbit/s or for
PROFINET
copper cable and due to the electrical isolation, EMC protection and equipotential
bonding aspects, it is recommended that fiber-optic cables be used for connections between
buildings.
Additional information
