Classification
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 compatibil-
ity with other products and systems. The guide-
line 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:
First environment (residential area with light industry) with restricted distribution

• 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 con-
cerned, in proportion to their share in expanding
the electrical equipment involved.
