● For copper, at least 6 mm²
● For aluminum, at least 16 mm²
● For steel, at least 50 mm²
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
Further information on the protective connection and equipotential bonding can be found in
the following references:
● SINAMICS drive system: See the SINAMICS manuals

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.
