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 compa-
tibility 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 manu-
facturer of the machine or system concerned, in
proportion to their share in expanding the electrical
equipment involved.
