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). It also guarantees that the product meets the various requirements
placed upon it (such as the EMC Directive and possibly other directives according to the so-called
new procedure).
Vacon NXL 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 they are 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 NXL frequency converters with the EMC directive is verified with Technical
Construction 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 Directive 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
EMC compliance is a major consideration for Vacon NXL drives from the outset of the design.
Vacon NXL frequency converters are marketed throughout the world, a fact which makes the EMC
requirements of customers different. As far as the immunity is concerned, all Vacon NXL 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 NXL frequency converters are divided into two classes according to the level of
electromagnetic disturbances emitted. There is no difference in the functions or the control
electronics between these classes but their EMC properties vary as follows:
