ABB ACS550-01-04A1-4 [12/44] Components or sub assemblies intended for incorporation into an apparatus by other manufacturers or assemblers

12 EMC compliant installation and configuration for a PDS | Technical guide No. 3

Types of equipment

The EMC Directive (2004/108/EC) defines equipment as any ap-

paratus or fixed installation. As there are separate provisions for

apparatus and fixed installations, it is important that the correct

category of the equipment (PDM, CDM or BDM) is determined.

In technical-commercial classifications the following terminol-

ogy is frequently used: components, sub-assemblies, finished

appliances (ie, finished products), a combination of finished

appliances (ie, a system), apparatus, fixed installations and

equipment.

The key issue here is whether the item is meant for end users

or not:

– if it is meant for end users, the EMC directive applies;

– if it is meant for manufacturers or assemblers, the EMC

directive does not apply.

Components or sub-assemblies intended for incorporation

into an apparatus by the end users

A manufacturer may place components or sub-assemblies on

the market, which are:

– for incorporation into an apparatus by the end-user,

– available to end-users and likely to be used by them.

These components or sub-assemblies are to be considered as

apparatus with regard to the application of the EMC. The instruc-

tions for use accompanying the component or sub-assembly

should include all relevant information, and should assume that

adjustments or connections can be performed by an end user

not aware of the EMC implications.

Some variable speed power drive products fall into this category,

eg, a drive with enclosure and sold as a complete unit (CDM) to

the end user who installs it into his own system. All provisions

of the EMC Directive will apply ( CE mark, EC declaration of

conformity and technical documentation).

Components or sub-assemblies intended for incorporation

into an apparatus by other manufacturers or assemblers

Components or sub-assemblies intended for incorporation into

an apparatus or another sub-assembly by other manufacturers

or assemblers are not considered to be “apparatus” and are

therefore not covered by the EMC Directive. These components

include resistors, cables, terminal blocks, etc.
