2. EU DIRECTIVE
2.1 CE marking
The CE marking on the product guarantees the free movement of the product within the EEA (European
Economic Area).
Vacon NX frequency converters carry the CE label as a proof of compliance with the Low Voltage Directive
(LVD) and the Electro Magnetic Compatibility (EMC). The company
SGS FIMKO has acted as the Competent
Body.
2.2 EMC
directive
2.2.1 General
The EMC Directive provides that the electrical apparatus must not excessively disturb the environment it is
used in, and, on the other hand, it shall have an adequate level of immunity toward other disturbances from
the same environment.
The compliance of Vacon NX frequency converters with the EMC directive is verified with Technical Con-
struction Files (TCF) checked and approved by SGS FIMKO, which is a
Competent Body . The Technical
Construction Files are used to authenticate the comformity of Vacon frequency converters with the Direc-
tive because such a large-sized product family is impossible to be tested in a laboratory environment and
because the combinations of installation vary greatly.
2.2.2 Technical criteria
Our basic idea was to develop a range of frequency converters offering the best possible usability and cost-
efficiency. EMC compliance was a major consideration from the outset of the design.
Vacon NX frequency converters are marketed throughout the world, a fact which makes the EMC require-
ments of customers different. As far as the immunity is concerned, all Vacon NX frequency converters are
designed to fulfil even the strictest requirements, while as regards the emission level, the customer may
want to upgrade Vacon's already high ability to filter electro-magnetic disturbances.
2.2.3 Vacon frequency converter EMC classification
Vacon NX frequency converters are divided into four classes according to the level of electromagnetic
disturbances emitted. The EMC class of each product is defined in the type designation code.
Class C (NX_5, FR4 to FR6, Protection class IP54):
Frequency converters of this class fulfil the requirements of the product standard EN 61800-3+A11 for
the 1st environment (unrestricted distribution) and the 2nd environment.
The emission levels correspond to the requirements of EN 61000-6-3.
Note: If the protection class of the frequency converter is IP21, the requirements of Class C are fulfilled
only as far as the conducted emissions are concerned.
Class H:
Vacon NX_5 frequency converters (FR4 to FR9) and NX_2 frequency converters (FR4 to FR6) have been
designed to fulfil the requirements of the product standard EN 61800-3+A11 for the 1st environment
restricted distribution and the 2nd environment.
The emission levels correspond to the requirements of EN 61000-6-4.
Class L (NX_6 FR6 to FR9 only):
Provides filtering for the 2
nd environment, restricted distribution according to EN 61800-3+A11.
