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-650 GP/AF-600 FP series Design Guide.
NB!
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 200 mm (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 degrees.
