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_ AC 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, on the other hand, it shall have an adequate level of immunity toward other disturbances from
the same environment.
The compliance of Vacon NX_ AC 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 Vacon AC drives 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
Our basic idea was to develop a range of AC drives offering the best possible usability and cost-efficiency.
EMC compliance was a major consideration from the outset of the design.
Vacon NX_ AC drives are marketed throughout the world, a fact which makes the EMC requirements of
customers different. As far as the immunity is concerned, all Vacon NX_ AC drives 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 AC drive EMC classification
Vacon NX_ AC drives are divided into five classes according to the level of electromagnetic disturbances
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.
Vacon EMC class C (NX_5, FR4 to FR6, Protection class NEMA12):
AC drives 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 AC drive is NEMA1 the requirements of class C are fulfilled only as far as the conducted
emissions are concerned.
Vacon EMC class H (NX_5, FR4 to FR9 and NX_2, FR4 to FR9):
AC drives 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 AC drives can be used both in the 1st and the 2nd environment.
