How to Install PROFINET Operating Instruction

3.1.7 EMC Precautions

The following EMC precautions are recommended in order to achieve interference-free operation of the Ethernet network.
Additional EMC information is available in the AF-600 FP/AF-650 GP series Design Guide.
NOTE
3 3
Relevant national and local regulations, for example regarding protective earth connection, must be observed.
The Ethernet communication cable must be kept away from motor and brake resistor cables to avoid coupling of high frequency
noise from one cable to the other. Normally a distance of 200mm (8 inches) is sufficient, but maintaining the greatest possible
distance between the cables is recommended, especially where cables run in parallel over long distances. When crossing is
unavoidable, the Ethernet cable must cross motor and brake resistor cables at an angle of 90°.
