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).
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 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.
2.2.2 Technical criteria
EMC compliance is a major consideration for NXL drives from the outset of the design. NXL
frequency converters are marketed throughout the world, a fact which makes the EMC requirements
of customers different. All NXL frequency converters are designed to fulfil even the strictest immunity
requirements.
2.2.3 NXL frequency converter EMC classification
NXL frequency converters are divided into two classes according to the level of electromagnetic
disturbances emitted. Later in this manual the division is made according to the mechanical sizes
(MF2, MF3, etc.). The technical data of the different sizes can be found in Chapter 0.
Class C (NXL HVAC IP54):
NXL HVAC drives with IP54 enclosure are delivered as class C products with an integrated RFI
filter. NXL HVAC drives IP54 selection fulfil the requirements of the product standard EN 61800-
3 (2004) category C1 (EN 55011 class B).
The emission levels correspond to the requirements of EN 61000-6-3.
Class N (NXL Compact):
No EMC emission protection. NXL Compact drives (frames MF2 and MF3) are delivered from the
factory without an integrated RFI filter as class N products. External RFI filters for these products for
class H are available.
Class H (NXL HVAC IP21):
NXL HVAC drives with IP21 enclosure are delivered as class H products with an integrated RFI
filter. NXL HVAC drives IP21 selection fulfil the requirements of the product standard EN 61800-
3 (2004) category C2 (EN 55011 class A).
The emission levels correspond to the requirements of EN 61000-6-4.
Class T:
The T-class converters have a small earth current and can be used with IT supplies only. If they are
used with other supplies no EMC requirements are complied with.
