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).
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

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 NX frequency converters with the EMC directive is verified with Technical Construction
Files (TCF) checked and approved by SGS FIMKO, which is a
Construction Files are used to authenticate the comformity of the NX 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.
NX 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 NX frequency converters are designed to fulfil
even the strictest requirements, while as regards the emission level, the customer may want to upgrade
NX's already high ability to filter electro-magnetic disturbances.
2.2.3

Frequency converter EMC classification

NX frequency converters are divided into five classes according to the level of electromagnetic distur-
bances emitted, the requirements of a power system network and the installation environment (see chapter
2.2.3.1). 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 comply with the requirements of category C1 of the product standard
EN 61800-3 (2004). Category C1 ensures the best EMC characteristics and it includes converters the rated
voltage of which is less than 1000V and which are intended for use in the 1st environment. 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 (NX_5, FR4 to FR9 and NX_2, FR4 to FR9):
Frequency converters of this class comply with the requirements of category C2 of the product standard
EN 61800-3 (2004). Category C2 includes converters in fixed installations and the rated voltage of which is
less than 1000V. The class H frequency converters can be used both in the 1st and the 2nd environment.
Class L (Protection classes IP21 and IP54: NX_5 FR10 and greater, NX_6 FR6 and greater):
Frequency converters of this class comply with the requirements of category C3 of the product standard
EN 61800-3 (2004). Category C3 includes converters the rated voltage of which is less than 1000V and
which are intended for use in the second environment only.
