Operating instructions

2.1.3. EMC Precautions
The following EMC precautions are recommended in order to achieve interference-free operation
of the DeviceNet network. Additional EMC information is available in the relevant FC 100, 200 or
300 Operating Instructions and Design Guides.
NB!
Relevant national and local regulations, for example regarding protective earth con-
nection, must be observed.
The DeviceNet 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 it is generally recommended to keep the greatest possible distance
between the cables, especially where cables run in parallel over long distances. If the DeviceNet
cable has to cross a motor and brake resistor cable they must cross each other at an angle of 90
degrees.
