2.4.1. CE Conformity and Labeling
What is CE Conformity and Labeling?
The purpose of CE labeling is to avoid technical trade obstacles within the EFTA and the EU. The
EU has introduced the CE label as a simple way of showing whether a product complies with the
relevant EU directives. The CE label says nothing about the specifications or quality of the product.
Adjustable frequency drives are regulated by three EU directives:
The machinery directive (98/37/EEC)
All machines with critical moving parts are covered by the Machinery Directive of January 1, 1995.
Since an adjustable frequency drive is largely electrical, it does not fall under the Machinery Di-
rective. However, if an adjustable frequency drive is supplied for use in a machine, we provide
information on its safety aspects in the manufacturer's declaration.
The low-voltage directive (73/23/EEC)
Adjustable frequency drives must be CE-labeled in accordance with the Low-voltage Directive of
January 1, 1997. The directive applies to all electrical equipment and appliances used in the
50-1000 V AC and the 75-1500 V DC voltage ranges. Danfoss uses CE labels in accordance with
the directive and will issue a declaration of conformity upon request.
The EMC directive (89/336/EEC)
EMC is short for electromagnetic compatibility. The presence of electromagnetic compatibility
means that the mutual interference between different components/appliances does not affect the
way the appliances work.
The EMC directive came into effect January 1, 1996. Danfoss uses CE labels in accordance with
the directive and will issue a declaration of conformity upon request. To carry out EMC-correct
installation, see the instructions in this Design Guide. In addition, we specify the standards with
which our products comply. We offer the filters presented in the specifications and provide other
types of assistance to ensure the optimum EMC result.
The adjustable frequency drive is most often used by professionals of the trade as a complex
component forming part of a larger appliance, system or installation. It must be noted that the
responsibility for the final EMC properties of the appliance, system or installation rests with the
installer.

Guidelines on the Application of Council Directive 89/336/EEC
The adjustable frequency drive is sold directly to the end-consumer. For example, it may
be sold to a DIY market. The end-consumer is a layman. He installs the adjustable fre-
quency drive himself for use with a hobby machine, a kitchen appliance, etc. For such
applications, the adjustable frequency drive must be CE-labeled in accordance with the
EMC directive.
The adjustable frequency drive is sold for installation in a plant. The plant is built up by
professionals of the trade. It could be a production plant or a heating/ventilation plant
designed and installed by professionals of the trade. Neither the adjustable frequency
drive nor the finished plant must be CE-labeled under the EMC directive. However, the
unit must comply with the basic EMC requirements of the directive. This is ensured by
using components, appliances and systems that are CE-labeled under the EMC directive.
The adjustable frequency drive is sold as part of a complete system. The system is being
marketed as complete and could, for example, be an air-conditioning system. The com-
MG.33.B9.22 - VLT ® is a registered Danfoss trademark.
