2. DIRECTIVES
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
defined by the directive.
The NX frequency drives 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 also, it shall have an adequate level of immunity toward other
disturbances from the same environment.
The compliance of the NX frequency drives 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 the NX frequency drives
with the Directive due to the large product family & variety of installations possibilities.
2.2.2 Technical criteria
The NX frequency drives are marketed throughout the world, a fact which makes the EMC
requirements of customers different. As far as the immunity is concerned, all NX frequency drives
are designed to fulfil even the strictest requirements, while as regards the emission level, the
customer may want to upgrade the NX's already high ability to filter electro-magnetic
disturbances.
2.2.3 NX frequency drive EMC classification
The NX frequency drives are divided into three 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:
Class H:
NX_5 frequency drives (FR4 to FR9) and NX_2 frequency drives (FR4 to FR6) have been
designed to fulfil the requirements of the product standard IEC 61800-3+A11 for the 1st
environment restricted distribution and the 2nd environment.
The emission levels correspond to the requirements of IEC 61000-6-4.
Class L (NX_5, FR10 only):
Provides filtering for the 2 nd environment, restricted distribution according to IEC 61800-3+A11.
