NOTICE
Fault of the data link or device defect with missing equipotential bonding
Considerable leakage currents can flow via the data cable if equipotential bonding is not
provided. Disturbance of the data link or device faults may result.
Install an equipotential bonding conductor together with the data cable.
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
