CE labelling can cover many different specifications socheck the CE label to ensure that it covers the relevantapplications.Danfoss CE labels the frequency converters in accordancewith the low-voltage directive, meaning that if thefrequency converter is installed correctly, Danfossguarantees compliance with the low-voltage directive.Danfoss issues a declaration of conformity that confirmsour CE labelling in accordance with the low-voltagedirective.If following the instructions for EMC-correct installationand filtering, the CE label also applies.5.10 EMC-correct Installation offers detailed instructions forEMC-correct installation. Furthermore, Danfoss specifieswhich our products comply with.2.3.4 Compliance with EMC Directive2004/108/ECThe primary users of the frequency converter are tradeprofessionals, who use it as a complex component formingpart of a larger appliance, system, or installation. Theresponsibility for the final EMC properties of the appliance,system, or installation rests with the installer. As an aid tothe installer, Danfoss has prepared EMC installationguidelines for the Power Drive system. If the EMC-correctinstructions for installation are followed, the standards andtest levels stated for power drive systems are compliedwith. See 2.10 Immunity Requirements.2.4 Air HumidityThe frequency converter has been designed to meet theIEC/EN 60068-2-3 standard, EN 50178 pkt. 9.4.2.2 at 50 °C.2.5 Aggressive EnvironmentsA frequency converter contains many mechanical andelectronic components. All are to some extent vulnerableto environmental effects.CAUTIONThe frequency converter must not be installed inenvironments with airborne liquids, particles, or gasescapable of affecting and damaging the electroniccomponents. Failure to take the necessary protectivemeasures increases the risk of stoppages, thus reducingthe life of the frequency converter.Degree of protection as per IEC 60529The safe stop function can only be installed and operatedin a control cabinet with degree of protection IP54 orhigher (or equivalent environment) to avoid cross faultsand short circuits between terminals, connectors, tracks,and safety-related circuitry caused by foreign objects.Liquids can be carried through the air and condense in thefrequency converter and can cause corrosion ofcomponents and metal parts. Steam, oil, and salt water cancause corrosion of components and metal parts. In suchenvironments, use equipment with enclosure rating IP54/IP55. As an extra protection, coated printed circuit boardscan be ordered as an option.Airborne Particles such as dust can cause mechanical,electrical, or thermal failure in the frequency converter. Atypical indicator of excessive levels of airborne particles isdust particles around the frequency converter fan. In dustyenvironments, use equipment with enclosure rating IP54/IP55 or a cabinet for IP00/IP20/NEMA 1 equipment.In environments with high temperatures and humidity,corrosive gases such as sulphur, nitrogen, and chlorinecompounds cause chemical processes on the frequencyconverter components.Such chemical reactions damage the electroniccomponents quickly. In such environments, mount theequipment in a cabinet with fresh air ventilation, keepingaggressive gases away from the frequency converter.An extra protection in such areas is a coating of theprinted circuit boards, which can be ordered as an option.NOTEMounting frequency converters in aggressive environmentsincreases the risk of stoppages and considerably reducesthe life of the converter.Before installing the frequency converter, check theambient air for liquids, particles, and gases by observingexisting installations in this environment. Typical indicatorsof harmful airborne liquids are water or oil on metal parts,or corrosion of metal parts.Excessive dust particle levels are often found on instal-lation cabinets and existing electrical installations. Oneindicator of aggressive airborne gases is blackening ofcopper rails and cable ends on existing installations.D and E enclosures have a stainless steel back channeloption to provide more protection in aggressiveenvironments. Proper ventilation is still required for theinternal components of the frequency converter.
