The Emc Directive (89/336/Eec); What Is Covered; Danfoss Vlt ® Drivemotor And Ce Labelling; Compliance With Emc Directive 89/336/Eec - Danfoss FCM 300 Series Design Manual

The EMC directive (89/336/EEC)

EMC is short for electromagnetic compatibility. The
presence of electromagnetic compatibility means that
the mutual interference between different components/
appliances is so small that the functioning of the
appliances is not affected. The EMC directive came
into force on 1 January 1996. The directive
distinguishes between components, appliances,
systems and installations.

What is covered?

The EU "Guidelines on the Application of Council
Directive 89/336/EEC" outline three typical situations
of using a FC motor. For each of these situations,
explanations are offered as to whether the situation in
question is covered by the EMC directive and must
be CE labelled.
1. The FC motor is sold directly to the end-
consumer. The FC motor is for example sold to a
DIY market. The end-consumer is a layman. He
installs the FC motor himself for use with a hobby
machine, a kitchen appliance, etc. For such
applications, the FC motor must be CE labelled in
accordance with the EMC directive.
2. The FC motor 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 plant designed and installed by
professionals of the trade. Neither the FC motor
nor the finished plant has to be CE labelled under
the EMC directive. However, the unit must comply
with the basic EMC requirements of the directive.
The installer can ensure this by using components,
appliances and systems that are CE labelled under
the EMC directive.
3. The FC motor is sold as part of a complete system.
The system is being marketed as complete. It could
be e.g. an air-conditioning system. The complete
system must be CE labelled in accordance with the
EMC directive. The manufacturer who supplies the
system can ensure CE labelling under the EMC
directive either by using CE labelled components or
by testing the EMC of the system. If he chooses to
use only CE labelled components, he does not have
to test the entire system.

FCM 300 Series
Danfoss FCM 300 Series motor and CE labelling
CE labelling is a positive feature when used for its
original purpose, i.e. to facilitate trade within the EU
and EFTA.
However, CE labelling may cover many different
specifications. This means that it has to be checked
what a given CE label specifically covers.
The specifications covered can in fact be widely
different. That is why a CE label can give the installer
a false feeling of security when using a FC motor as a
component in a system or an appliance.
We CE label our VLT ® DriveMotors in accordance with
the low-voltage directive. This means that as long as
the FC motor is installed correctly, we guarantee that
it complies with the low-voltage directive. We issue a
declaration of conformity that confirms our CE
labelling in accordance with the low-voltage directive.
The CE label also applies to the EMC directive, on
condition that the instructions given in the Operating
Instructions for EMC-correct installation and filtering
have been followed. On this basis, a declaration of
conformity in accordance with the EMC directive is
issued.
The Quick Guide gives detailed instructions for
installation to ensure that your installation is EMC-
correct. Furthermore, we specify which norms that
are complied with by our different products.
We offer the filters that can be seen from the
specifications and gladly provide other types of
assistance that can help you obtain the best EMC
result.

Compliance with EMC directive 89/336/EEC

In the great majority of cases, the VLT
used by professionals of the trade as a complex
component forming part of a larger appliance, system
or installation. It must be noted that the responsibility
for the final EMC properties of the appliance, system
or installation rests with the installer. As an aid to the
installer, Danfoss has prepared EMC installation
guidelines for the Power Drive System. The standards
and test levels stated for Power Drive Systems are
complied with, provided the right EMC-correct
instructions for installation have been followed, see
electrical installation.
