Notes on EMC
Further information
The paragraphs below describe selection of the
is available in the
electrical components in conformity with the
Technical Guide
EMC Guideline.
The aim of the EMC Guideline is, as the name
implies, to achieve electromagnetic compatibility
with other products and systems. The guideline
ensures that the emissions from the product
concerned are so low that they do not impair
another product's interference immunity.
In the context of the EMC Guideline, two aspects
must be borne in mind:
• the product's interference immunity
• the product's actual emissions

The EMC Guideline expects EMC to be taken into
account when a product is being developed;
however, EMC cannot be designed in, it can only
be quantitatively measured.
Note on EMC conformity
The conformity procedure is the responsibility of
both the power converter's supplier and the
manufacturer of the machine or system
concerned, in proportion to their share in
expanding the electrical equipment involved.
