Appendix 8 Emc And Low Voltage Directives; Appendix 8.1 Requirements For Compliance With The Emc Directive - Mitsubishi Electric MELSEC-L SSCNETIII/H User Manual

Appendix 8
Compliance to the EMC Directive, which is one of the EU Directives, has been a legal obligation for the products sold
in European countries since 1996 as well as the Low Voltage Directive since 1997.
Manufacturers who recognize their products are compliant to the EMC and Low Voltage Directives are required to
attach a "CE mark" on their products.

Appendix 8.1
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.
