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
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
°.
