Appendix 5 Emc, Low Voltage, And Machinery Directives; Measures To Comply With The Emc Directive - Mitsubishi Electric NZ2GFSS2 32D S1 User Manual

Appendix 5
In each country, laws and regulations concerning electromagnetic compatibility (EMC) and electrical safety are enacted.
For the products sold in the European countries, compliance with the EU's EMC Directive has been a legal obligation as EMC
regulation since 1996, as well as the EU's Low Voltage Directive as electrical safety regulation since 1997.
Also, compliance with the EU's Machinery Directive has been a legal obligation since 1995.
Manufacturers who recognize their products are compliant with the EMC and Low Voltage Directives are required to attach a
"CE marking" on their products in European countries.
In some other countries and regions, manufacturers are required to make their products compliant with applicable laws or
regulations and attach a certification mark on the products as well (such as UK Conformity Assessed (UKCA) marking in the
UK, and Korea Certification (KC) marking in South Korea). Each country works to make their regulatory requirements
consistent across countries based on international standards. When the requirements are consistent, measures to comply
with the EMC and electrical safety regulations become common across countries.
The UK and South Korea have enacted EMC regulations whose requirements are consistent with those of the EMC Directive.
The UK has also enacted electrical safety regulations whose requirements are consistent with those of the Low Voltage
Directive. In this section, the requirements of the EMC and Low Voltage Directives are described as examples of those of the
EMC and electrical safety regulations.

Measures to comply with the EMC Directive

The EMC Directive sets requirements for emission (conducted and radiated electromagnetic interference emitted by a
product) and immunity (the ability of a product not to be influenced by externally generated electromagnetic interference).
This section describes the precautions for machinery constructed with the MELSEC iQ-R series modules to comply with the
EMC Directive.
These precautions are based on the requirements of the EMC Directive and the harmonized standards. However, they do not
guarantee that the entire machinery constructed according to the descriptions complies with the EMC Directive.
The manufacturer of the machinery must determine the testing method for compliance and declare conformity to the EMC
Directive.
