The paragraphs below describe selection
of the electrical components in conformity
with the 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 devel-
oped; 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 con-
cerned, in proportion to their share in expand-
ing the electrical equipment involved.
