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 a frequency converter is
largely electrical, it does not fall under the machinery
directive. However, if a 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.
