Appendix 9 Emc And Low Voltage Directives; Measures To Comply With The Emc Directive - Mitsubishi Electric MELSEC L Series User Manual

Appendix 9
Compliance with the EMC Directive, which is one of the EU directives, has been mandatory for products sold within EU
member states since 1996 as well as compliance with the Low Voltage Directive since 1997.
For products compliant to the EMC and Low Voltage Directives, their manufacturers are required to declare
compliance and affix the CE marking.

Appendix 9.1
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-L 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.

Programmable controller is an open-type device intended to be placed in a conductive control panel or similar type of
enclosure. The tests were conducted with the programmable controller installed in a control panel, applying the
maximum rated input voltage of the power supply module.
