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 3 EU
directives:
The machinery directive (98/37/EEC)
All machines with critical moving parts are covered by the
machinery directive. 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, Danfoss provides information on safety aspects
relating to the frequency converter. Danfoss does this with
a manufacturer's declaration.
The low-voltage directive (73/23/EEC)
Frequency converters must be CE labelled in accordance
with the low-voltage directive. The directive applies to all
electrical equipment and appliances used in the 50-1000 V
AC and the 75-1500 V 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.
Danfoss CE labels in accordance with the directive and
issues a declaration of conformity upon request. To carry
out EMC-correct installation, this manual gives detailed
instructions for installation. In addition, Danfoss specifies
the standards which our different products comply with.
The frequency converter is most often used by profes-
sionals 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.
