4.1.7 EMC Precautions
The following EMC precautions are recommended in order to achieve interference-free operation of the LonWorks network. Additional EMC information
is available in the
VLT HVAC Drive Design Guide
.
NB!
N.B.:
Relevant national and local regulations, for example regarding protective earth connection, must be observed.
The LonWorks 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 LonWorks cable must cross motor and brake resistor cables
at an angle of 90 degrees.
NB!
It is highly recommended to use suitable screened cable for any LonWorks installation!
