Ce Labelling - Danfoss VLT 8000 AQUA series Operating Instructions Manual

CE labelling

What is CE labelling?
The purpose of CE labelling is to avoid technical
obstacles to trade within EFTA and the EU. The
EU has introduced the CE label as a simple way of
showing whether a product complies with the relevant
EU directives. The CE label says nothing about the
specifications or quality of the product. frequency
converters are regulated by three EU directives:
The machinery directive (98/37/EEC)
All machines with critical moving parts are covered by
the machinery directive, which came into force on 1
January 1995. Since an frequency converter is largely
electrical, it does not fall under the machinery directive.
However, if an frequency converter is supplied for
use in a machine, we provide information on safety
aspects relating to the frequency converter. We do
this by means of a manufacturer's declaration.
The low-voltage directive (73/23/EEC)
frequency converters must be CE labelled in
accordance with the low-voltage directive, which came
into force on 1 January 1997. The directive applies to
all electrical equipment and appliances used in the 50 -
1000 Volt AC and the 75 - 1500 Volt DC voltage ranges.
Danfoss CE labels in accordance with the directive and
issues a declaration of conformity upon request.
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.
Danfoss CE labels in accordance with the directive and
issues a declaration of conformity upon request. In
order that EMC-correct installation can be carried out,
this manual gives detailed instructions for installation. In
addition, we specify the standards which our different
products comply with. We offer the filters that can be
seen from the specifications and provide other types of
assistance to ensure the optimum EMC result.
In the great majority of cases, the frequency converter
is 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.

What is covered
The EU "Guidelines on the Application of Council
Directive 89/336/EEC" outline three typical situations
of using an frequency converter. 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 frequency converter is sold directly to the
end-consumer. The frequency converter is for
example sold to a DIY market. The end-consumer
is a layman. He installs the frequency converter
himself for use with a hobby machine, a kitchen
appliance, etc. For such applications, the
frequency converter must be CE labelled in
accordance with the EMC directive.
2. The frequency converter 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 frequency
converter 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 frequency converter 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.
