Technical InformationMICROMASTERMICROMASTER VectorMIDIMASTER Vector3.10 Compliance with EMC DirectiveAll manufacturers / assemblers of electrical apparatus whichperforms a complete intrinsic function which is placed on themarket as a single unit intended for the end user must complywith the EMC directive EEC/89/336 after January 1996. Thereare three routes by which the manufacturer/assembler candemonstrate compliance:1. Self-CertificationThis is a manufacturer's declaration that the Europeanstandards applicable to the electrical environment forwhich the apparatus is intended have been met. Onlystandards which have been officially published in theOfficial Journal of the European Community can becited in the manufacturer's declaration.2. Technical Construction FileA technical construction file can be prepared for theapparatus describing its EMC characteristics. This filemust be approved by a ‘Competent Body’ appointedby the appropriate European government organisation.This approach allows the use of standards which arestill in preparation.3. EC Type-Examination CertificateThis approach is only applicable to radiocommunication transmitting apparatus.The MICROMASTER, MICROMASTER Vector andMIDIMASTER Vector units do not have an intrinsic functionuntil connected with other components (e.g. a motor).Therefore, the basic units are not allowed to be CE markedfor compliance with the EMC directive. However, full detailsare provided below of the EMC performance characteristics ofthe products when they are installed in accordance with thewiring recommendations in section 9.3.Three classes of EMC performance are available as detailedbelow. Note that these levels of performance are onlyachieved when using the default switching frequency (or less)and a maximum motor cable length of 25 m.Class 1: General IndustrialCompliance with the EMC Product Standard for Power Drive Systems EN 61800-3 for use in Second Environment (Industrial)and Restricted Distribution.EMC Phenomenon Standard LevelEmissions:Radiated Emissions EN 55011 (VDE 0875 Part 11) Level A1 *Conducted Emissions EN 61800-3 (VDE 0160 Part 100) *Immunity:Electrostatic Discharge EN 61000-4-2 (VDE 0847 Part 4-2) 8 kV air dischargeBurst Interference EN 61000-4-4 (VDE 0847 Part 4-4) 2 kV power cables, 1 kV controlRadio Frequency Electromagnetic Field IEC 1000-4-3 (VDE 0847 Part 4-3) 26-1000 MHz, 10 V/m* Emission limits not applicable inside a plant where no other consumers are connected to the same electricity supply transformer3/14 Siemens DA 64 – 1998/99 (04/99)
