CAUTIONINTERNAL FAILURE HAZARDAn internal failure in the frequency converter can resultin serious injury, when the frequency converter is notproperly closed.• Ensure that all safety covers are in place andsecurely fastened, before applying power.CAUTIONUNINTENDED MOTOR ROTATIONWINDMILLINGUnintended rotation of permanent magnet motors canresult in serious injury or equipment damage.• Ensure that permanent magnet motors areblocked to prevent unintended rotation.2.1.1 Disposal InstructionDo not dispose of equipment containingelectrical components together withdomestic waste.Collect it separately in accordance withlocal and currently valid legislation.Table 2.2 Disposal Instruction2.2 CE Labelling2.2.1 CE Conformity and LabellingWhat is CE conformity and labelling?The purpose of CE labelling is to avoid technical tradeobstacles within EFTA and the EU. The EU has introducedthe CE label as a simple way of showing whether aproduct complies with the relevant EU directives. The CElabel says nothing about the specifications or quality ofthe product. Frequency converters follow three EUdirectives:The machinery directive (2006/42/EC)Frequency converters with integrated safety function arenow falling under the machinery directive. Danfoss CE-labels in accordance with the directive and issues adeclaration of conformity upon request. Frequencyconverters without safety function do not fall under themachinery directive. However, if a frequency converter issupplied for use in a machine, we provide information onsafety aspects relating to the frequency converter.The low-voltage directive (2006/95/EC)Frequency converters must be CE labelled in accordancewith the low-voltage directive of January 1, 1997. Thedirective applies to all electrical equipment and appliancesused in the 50–1000 V AC and the 75–1500 V DC voltageranges. Danfoss CE-labels in accordance with the directiveand issues a declaration of conformity upon request.The EMC directive (2004/108/EC)EMC is short for electromagnetic compatibility. Thepresence of electromagnetic compatibility means that themutual interference between different components/appliances does not affect the way the appliances work.The EMC directive came into effect January 1, 1996.Danfoss CE-labels in accordance with the directive andissues a declaration of conformity upon request. To carryout EMC-correct installation, see chapter 5.7 EMC-correctInstallation. In addition, we specify which standards ourproducts comply with. We offer the filters presented in thespecifications and provide other types of assistance toensure the optimum EMC result.Trade professionals use the frequency converter as acomplex component forming part of a larger appliance,system, or installation. The responsibility for the final EMCproperties of the appliance, system, or installation restswith the installer.2.2.2 What Is CoveredThe EU "Guidelines on the Application of Council Directive2004/108/EC" outline three typical situations for using afrequency converter. See chapter 2.2.3 Danfoss FrequencyConverter and CE Labelling and chapter 2.2.4 Compliancewith EMC Directive 2004/108/EC for CE labelling and EMCcoverage.1. The frequency converter is sold directly to theend-consumer. The frequency converter is forexample sold to a DIY market. The end-consumeris a layman who uses the frequency converterwith a hobby machine, or household appliance.For such applications, the frequency convertermust be CE labelled in accordance with the EMCdirective.2. The frequency converter is sold for installation ina plant, such as a production plant or a heating/ventilation plant designed and installed by tradeprofessionals. The frequency converter and thefinished plant do not have to be CE labelledunder the EMC directive. However, the unit mustcomply with the basic EMC requirements of thedirective. Use components, appliances, andsystems that are CE labelled under the EMCdirective.Introduction Design Guide14 Danfoss A/S © Rev. 05/2014 All rights reserved. MG16C20222
