VLT ® 2000 Series I Danfoss VLT frequency converter and CE labelling CE labelling is a positive feature when used for its ori- ginal purpose, ie. to facilitate trade within the EU and EFTA. However, CE labelling may cover many different specifications. This means that it has to be checked what a given CE label specifically covers. The specifications covered can in fact be widely different. That is why the CE label can give installers a false feeling of security when using a frequency con- verter as a component in a system or an appliance. Special conditions To help ensure that your installation is EMC-correct, the manual provides detailed instructions for installa- tion.
Furthermore, we specify which norms that are complied with by which of our products. We offer the filters that can be seen from the specifications and gladly provide other types of assi- stance that can help you obtain the best EMC result. We CE label our VLT frequency converter in accordance with the low-voltage directive. This means that as long as the frequency converter is installed correctly, we guarantee that it complies with the low-voltage directive. We issue a declaration of conformity confirming that our CE label complies with the low-voltage directive.
Section 1 Section 2 Section 3 The CE mark also applies to the EMC directive, on condition that the instructions given in the manual for EMC correct installation and filtering are followed. On that basis a declaration of conformity with the EMC directive is issued. I Compliance with EMC directive 89/336/EEC In support of our claim that the VLT frequency conver- ter complies with the protection requirements for emission and immunity under EMC directive 89/336/ EEC, a Technical Construction File (TCF) has been prepared for each model.
Such a file defines the EMC requirements and the measurements made in accordance with harmonised EMC standards in a Power Drive System (PDS) that consists of a VLT frequency converter, a control cable and the controls (control box), motor cable and motor plus any options added. The Technical Construction File is prepared on this basis in cooperation with a duly authorised EMC laboratory (Competent Body). In most cases the VLT frequency converter is used by professionals of the trade as a complex component forming part of a larger applicance, system or installa- tion.
It must be noted that the responsibility for the fi- nal EMC properties of the applicance, system or in- stallation rests with the installer. As an aid to the installer, Danfoss has prepared EMC installation guidelines for the Power Drive System. The standards and testing levels stated for the Power Drive System are complied with, provided that the EMC-correct in- stallation guidelines are applied.
