VLT ® FCM Series3. The FC motor is sold as part of a complete system.The system is being marketed as complete. It couldbe e.g. an air-conditioning system. The completesystem must be CE labelled in accordance withthe EMC directive. The manufacturer who suppliesthe system can ensure CE labelling under the EMCdirective either by using CE labelled components orby testing the EMC of the system. If he choosesto use only CE labelled components, he doesnot have to test the entire system.■ Danfoss FCM 300 Series motor and CE labellingCE labelling is a positive feature when used for its originalpurpose, i.e. to facilitate trade within the EU and EFTA.However, CE labelling may cover many differentspecifications. This means that it has to be checkedwhat a given CE label specifically covers.The specifications covered can in fact be widelydifferent. That is why a CE label can give the installera false feeling of security when using a FC motor asa component in a system or an appliance.We CE label our VLT ® DriveMotors in accordance withthe low-voltage directive. This means that as long asthe FC motor is installed correctly, we guarantee thatit complies with the low-voltage directive. We issue adeclaration of conformity that confirms our CE labellingin accordance with the low-voltage directive.The CE label also applies to the EMC directive,on condition that the instructions given in theOperating Instructions for EMC-correct installationand filtering have been followed. On this basis,a declaration of conformity in accordance withthe EMC directive is issued.The Quick Guide gives detailed instructions forinstallation to ensure that your installation isEMCcorrect. Furthermore, we specify which normsthat are complied with by our different products.We offer the filters that can be seen fromthe specifications and gladly provide other types ofassistance that can help you obtain the best EMC result.■ Compliance with EMC directive 89/336/EECIn the great majority of cases, the VLT DriveMotoris used by professionals of the trade as a complexcomponent forming part of a larger appliance,system or installation. It must be noted that theresponsibility for the final EMC properties of theappliance, system or installation rests with the installer.As an aid to the installer, Danfoss has prepared EMCinstallation guidelines for the Power Drive System.The standards and test levels stated for PowerDrive Systems are complied with, provided the rightEMC-correct instructions for installation have beenfollowed, see electrical installation.■ EMC standardsNB!:- All EMC specifications are stated withfactory settings.- Maximum 4 kHz switching frequency.- Screened data/control cables must be usedfor surge protection.- The FC motor must be connected to earthin order to comply.- Maximum/minimum line impedance Z max =0.24 + j0.15 ohm; Z min = 0 + j0 ohm.
