Requirements to Meet EMC Directive
EMC Directives are those which require "any strong electromagnetic force is not output to the external.:Emission
(electromagnetic interference)" and "It is not influenced by the electromagnetic wave from the external.: Immunity
(electromagnetic sensitivity)".
Items EMC directive thru Grounding 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 above test items are conducted in the condition where the GOT is installed on the conductive control panel and combined
with the Mitsubishi PLC.
