9.3 Electro-Magnetic Compatibility (EMC)
All manufacturers / assemblers of electrical
apparatus which performs a complete
intrinsic function which is placed on the
market as a single unit intended for the end
user must comply with the EMC directive
EEC/89/336 after January 1996. There are
three routes by which the
manufacturer/assembler can demonstrate
compliance:
1.
Self-Certification
This is a manufacturer's declaration that the
European standards applicable to the
electrical environment for which the
apparatus is intended have been met. Only
standards which have been officially
published in the Official Journal of the
European Community can be cited in the
manufacturer's declaration.
2.
Technical Construction File
A technical construction file can be prepared
for the apparatus describing its EMC
characteristics. This file must be approved by
a ‘Competent Body’ appointed by the
appropriate European government
organisation. This approach allows the use of
standards which are still in preparation.
3.
EC Type-Examination Certificate
This approach is only applicable to radio
communication transmitting apparatus.
The MICROMASTER Integrated units do not have an intrinsic function until connected with other components
(e.g. a motor). Therefore, the basic units are not allowed to be CE marked for compliance with the EMC directive.
However, full details are provided below of the EMC performance characteristics of the products when they are
installed in accordance with the wiring recommendations in section 4.1 of this document.
Class 2: Filtered Industrial (Class A)
This level of performance will allow the manufacturer/assembler to self-certify their apparatus for
compliance with the EMC directive for the industrial environment as regards the EMC performance
characteristics of the power drive system. Performance limits are as specified in the Generic
Industrial Emissions and Immunity standards EN 50081-2 and EN 50082-2.
