Planning the electrical installation
The paragraphs below describe selection of the electri-
cal 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 immu-
nity.
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 quantita-
tively 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.
