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 and
the Electro Magnetic Compatibility Directive (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 must have an adequate level of immunity toward
other disturbances from the same environment.
The compliance of VACON
®
NX Liquid-Cooled 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 conformity 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 Liquid-Cooled 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
Liquid-Cooled AC drives are designed to fulfil even the strictest requirements.
2.2.3 VACON
®
AC drive EMC classification
VACON
®
NX Liquid-Cooled AC drive and inverter modules delivered from factory fulfil all EMC
immunity requirements (standard EN 61800-3).
The basic liquid cooled modules do not have any inherent emission filtering. If filtering is needed
and a certain EMC emission level is required, external RFI filters must be used.
Class N:
The VACON
®
NX Liquid-Cooled drives of this class do not provide EMC emission protection. This
kind of drives are mounted in enclosures. External EMC filtering is usually required to fulfil the EMC
emission requirements.
Class T:
The T-class AC drives have a smaller earth leakage current and are intended to be used with IT
supplies only. If they are used with other supplies no EMC requirements are complied with.
Warning: This is a product of the restricted sales distribution class according to IEC 61800-3. In a
domestic environment this product may cause radio interference in which case the user may be
required to take adequate measures.
