EMC and Low Voltage Directives
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.
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.
Appendix 8.1
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
Ethernet adapter module.
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 the above-mentioned directives.
Machine manufacturers are required to determine the method and judgment for complying with the EMC Directive at
their discretion.
(1) EMC Directive related standards
(a) Emission requirements
*1 QP: Quasi-peak value, Mean: Average value
*2 The Ethernet adapter module is an open-type device (a device designed to be housed inside other equipment) and must
be installed inside a conductive control panel. The corresponding tests were conducted with the Ethernet adapter
module installed inside a control panel.
