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 Vector and MIDIMASTER Vector 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 1.2.
Compliance Table (MMV):
Model No. EMC Class
MMV12 - MMV300 Class 2
MMV12/2 - MMV400/2 Class 1
MMV12/2 - MM400/2 with external filter (see table) 1 phase input only Class 2*
MMV37/3 - MMV750/3 Class 1
MMV220/3F - MMV750/3F Class 2*
MMV37/3 - MMV750/3 with external filter (see table, class A) Class 2*
MMV37/3 - MMV750/3 with external filter (see table, class B) Class 3*
Compliance Table (MDV):
Model No. EMC Class
MDV750/3 - MDV7500/3 Class 1
MDV550/2 - MDV4500/2 with class A external filter (see table) Class 2*
MDV550/2 - MDV1850/2 with class B external filter (see table) Class 3*
MDV550/2 - MDV4500/2 Class 1
MDV750/3 - MDV7500/3 with class A external filter (see table) Class 2*
MDV750/3 - MDV3700/3 with class B external filter (see table) Class 2*
MDV750/4 - MDV3700/4 Class 1
* If the installation of the inverter reduces the radio frequency field emissions (e.g. by installation in a
steel enclosure), Class 3 radiated emission limits will typically be met.
