Measures to Comply with the EMC Directive

The EMC Directive specifies that "products placed on the market must
be so constructed that they do not cause excessive electromagnetic
interference (emissions) and are not unduly affected by electromagnetic
interference (immunity)". This section summarizes the precautions on
compliance with the EMC Directive of the machinery constructed with
the MELSEC-L series modules.
These precautions are based on the requirements and the standards of
the regulation, however, it does not guarantee that the entire machinery
constructed according to the descriptions will comply with above-
mentioned directives.
The method and judgement for complying with the EMC Directive must
be determined by the person who constructs the entire machinery.
