1 OVERVIEW

1.2 Requirements to match EMC Directives

1.2.1 EMC Directives

1 - 4
EMC Directives which are among European Directives become forced.
EMC Directives are those which require "any strong electromagnetic force is not output
to the external.: Emission (electromagnetic interference)" and "It is influenced by the
electromagnetic wave from the external.: Immunity (electromagnetic sensitivity)".
Items 1.2.1 thru 1.2.3 summarize the precautions to use GOT and configure the
mechanical unit in order to match the EMC directives.
Though the data described herein are produced with our best on the basis of the
requirement items and standards of the restrictions gathered by Mitsubishi, they do not
completely guaranteed that all mechanical unit manufactured according to the data do
not always match the above directives. The manufacturer itself which manufactures
the mechanical unit must finally judge the method and others to match the EMC
directives.
The standards of the EMC Directives are shown below.

installed in a conductive control pauel or cabinet.
About these test items, install the control panel, combine with a PLC from this
company, and run a test.
