2.3 CE labeling
2.3.1 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 Directive. 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 50–1,000 V AC and the 75 –1,500 V DC voltage ranges. Danfoss CE labels in accordance with the directive and
issues 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 on January 1, 1996. Danfoss CE labels in accordance with the directive and issues 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.
