VLT® FCD Series 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 thespecifications or quality of the product. Frequencyconverters are regulated by three EU directives:The machinery directive (98/37/EEC)All machines with critical moving parts are coveredby the machinery directive, which came into force on1 January 1995. Since a frequency converter islargely electrical, it does not fall under the machinerydirective. However, if a frequency converter is sup-plied for use in a machine, we provide information onsafety aspects relating to the frequency converter.We do this by means of a manufacturer’s declaration.The low-voltage directive (73/23/EEC)Frequency converters must be CE labelled in accor-dance with the low-voltage directive, which cameinto force on 1 January 1997. The directive appliesto all electrical equipment and appliances used inthe 50 - 1000 Volt AC and the 75 - 1500 Volt DCvoltage ranges. Danfoss CE labels in accordancewith the directive and issues a declaration of confor-mity upon request.The EMC directive (89/336/EEC)EMC is short for electromagnetic compatibility. Thepresence of electromagnetic compatibility meansthat the mutual interference between different com-ponents/appliances is so small that the functioning ofthe appliances is not affected.The EMC directive came into force on 1 January1996. Danfoss CE labels in accordance with the di-rective and issues a declaration of conformity uponrequest. In order that EMC-correct installation canbe carried out, this manual gives detailed instruc-tions for installation. In addition, we specify thestandards which our different products comply with.We offer the filters that can be seen from the specifi-cations and provide other types of assistance toensure the optimum EMC result.In the great majority of cases, the frequency con-verter is used by professionals of the trade as acomplex component forming part of a larger appli-ance, system or installation. It must be noted that theresponsibility for the final EMC properties of the ap-pliance, system or installation rests with the installer.MG.04.A1.02 - VLT is a registered Danfoss trade mark 7Introduction to FCD 300
