3.2 Safety information for wiring
SIMOTION D4x5-2
46 Commissioning and Hardware Installation Manual, 02/2012
The following minimum cross-sections are required according to IEC 60364-5-54:
● 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
Further information on the protective connection and equipotential bonding can be found in
the following references:
