drive himself for use with a hobby machine, a kitche n appl iance, etc. For such applications, the
adjustable frequency drive must be CE-labeled in accordance with the EMC directive.
2. The a djustab le frequency drive is sold for installation in a plant. The plant is built up by professionals of the
trade. It could be a production plant or a heating/ventilation pla nt de signed and installed by professionals
of the trade. Neither the adjustable frequency drive nor the finished plant must be CE-labeled under the
EMC d irective. How ever, the unit must comply with the basic EMC requirem ents of the directive. T his is
ensured by using components, appliances, and systems that are CE-labeled unde r the EMC directive.
3. The adjustable frequency drive is sold as part of a complete system. The system is being marketed
as complete and could be e.g. an air conditioning system. ThecompletesystemmustbeCE-labeled
in accordance with the EMC directive. The manufacturer can ensure CE labeling under the EMC
directive either by using CE-labeled com p onents or by testing the EMC of the system. If it c hooses
to use only CE-labeled components, it does not have to test the entire system.
" Danfoss VLT Adjustable Frequency
Drive and CE L abeling
CE labeling is a positive feature when used for its original purpose, i.e. to facilitate trade within the EU and EFTA.
However, CE labeling may cover many d ifferent specifications. Thus, you must check
what a given CE labe l specifically covers.
The covered specificatio ns can be very different and a CE label may t
herefore give the installer a false sense
of security when using an adjustable frequency drive as a c omponent in a system or an appliance.
Danfoss CE labels the adjustable frequency drives in accordance with the l ow-voltage directive.
This means that if the adjustable frequency drive is inst alled correctly, we guarantee compliance
with the low -voltage directive. Danfoss issues a decl
aration of conformity that confirms our
CE labeling in accordance with the low-voltage directive.
The CE label also applies to the EMC directive p rovided that the instructions for EMC-correct installation and
filtering are follow ed . On this basis, a declaration of conformity in accordance with the EMC directive is issued.
The Design Guid e offers detailed instructions for inst allation to ensure EMC-correct installation.
Furthermore, Danfoss specifies which our d
ifferent products comply with.

" Compliance with EMC Directive 89/336/EEC
As mentioned, the adjustable fre quency drive is mostly used by p rofessionals of the trade as a complex
component forming part of a larger a
ppliance, system, or installation. It must be noted that the
responsibility for the final EMC properties of the appliance, system, or installation lies with the installer.
As an aid to the installer, Danfoss has pre pare d EMC installation guidelines for the Power Drive System.
The standards and test levels
stated for Power D rive Systems are complied with, pr ovided that the
EMC-correct instructions for installation are followed, see section Electrical Installation.
" Air Humidity
The adjustable frequen
cy drive has been designe d to meet the IEC/EN 60068-2-3 standard,
EN 50178 pkt. 9.4.2.2 at 122 °F (50°C).
