CE labellingWhat is CE labelling?The purpose of CE labelling is to avoid technical ob-stacles to trade within EFTA and the EU. The EU hasintroduced the CE label as a simple way of showingwhether a product complies with the relevant EU di-rectives. The CE label says nothing about the specifi-cations or quality of the product. Frequency convertersare regulated by three EU directives:•The machinery directive (98/37/EEC)All machines with critical moving parts are covered bythe machinery directive, which came into force on 1January 1995. Since a frequency converter is largelyelectrical, it does not fall under the machinery directive.However, if a frequency converter is supplied for usein a machine, we provide information on safety aspectsrelating to the frequency converter. We do this bymeans of a manufacturer's declaration.•The low-voltage directive (73/23/EEC)Frequency converters must be CE labelled in accord-ance with the low-voltage directive, which came intoforce on 1 January 1997. The directive applies to allelectrical equipment and appliances used in the 50 -1000 Volt AC and the 75 - 1500 Volt DC voltageranges. Danfoss CE labels in accordance with the di-rective and issues a declaration of conformity uponrequest.•The EMC directive (89/336/EEC)EMC is short for electromagnetic compatibility. Thepresence of electromagnetic compatibility means thatthe mutual interference between different compo-nents/appliances is so small that the functioning of theappliances is not affected.The EMC directive came into force on 1 January 1996.Danfoss CE labels in accordance with the directiveand issues a declaration of conformity upon request.In order that EMC-correct installation can be carriedout, this manual gives detailed instructions for instal-lation. In addition, we specify the standards which ourdifferent products comply with. We offer the filters thatcan be seen from the specifications and provide othertypes of assistance to ensure the optimum EMC result.In the great majority of cases, the frequency converteris used by professionals of the trade as a complexcomponent forming part of a larger appliance, systemor installation. It must be noted that the responsibilityfor the final EMC properties of the appliance, systemor installation rests with the installer.8 MG.27.E2.02 - VLT is a registered Danfoss trademark
