What is CE Labelling?
The purpose of CE labeling 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.
Adjustable frequency drives are regulated by three
EU directives:
The Machinery directive (89/392/EEC)
All machines with critical moving parts are covered
by the machinery directive, which came into force
on 1 January 1995. Since an adjustable frequency
drive is largely electrical, and the motor always will
be placed in connection with other machines, it
does not fall under the machinery directive.
However, if a FCM 300 is supplied for use in a
machine, we provide information on safety aspects
relating to the FCM 300. We do this by means of a
manufacturer's declaration.
The Low-voltage Directive (73/23/EEC)
Adjustable frequency drives must be CE labelled in
accordance with the low-voltage directive. The
directive applies to all electrical equipment and
appliances used in the voltage range of 50-1000 V
AC and 75-1500 V DC.
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.
Compliance with EMC Directive 89/336/EEC
In the great majority of cases, the VLT
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. As an aid to the installer, Danfoss has
17-2
FCM 300 Series
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.
What is Covered?
The EU "Guidelines on the Application of Council
Directive 89/336/EEC" outline three typical situations
of using a FCM 300. 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 labeled.
1. The FCM 300 is sold directly to the end-
consumer. The FCM 300 is for example sold to a
DIY (Do-it-yourself) market. The end-consumer is a
layman. He
for use with a hobby
appliance, etc. For such
the FCM 300 must be CE labeled in
accordance with the EMC directive.
2. The FCM 300 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 FCM 300
nor the finished plant has to be CE labeled 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 FCM 300 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 labeled in
®
DriveMotor
accordance with the EMC directive. The
manufacturer who supplies the system can ensure
CE labeling under the EMC directive either by using
CE labeled components or by testing the EMC of
the system. If he chooses to use only CE labeled
components, he does not have to test the entire
system.
