2 2
Unintended rotation of permanent magnet motors
causes risk of personal injury and equipment damage.
•
Ensure that permanent magnet motors are
blocked to prevent unintended rotation.
CAUTION
POTENTIAL HAZARD IN THE EVENT OF INTERNAL
FAILURE
Risk of personal injury when the frequency converter is
not properly closed.
•
Before applying power, ensure all safety covers
are in place and securely fastened.

2.2 Disposal Instruction

2.3 Approvals

Table 2.2 Approvals
The frequency converter complies with UL508C thermal
memory retention requirements. For more information
refer to chapter 3.5.1 Motor Thermal Protection.

2.4 CE Labeling

2.4.1 CE Conformity and Labeling
What is CE Conformity and Labeling?
The purpose of CE labeling is to avoid technical trade
obstacles 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 of January 1, 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, Danfoss provides

information on safety aspects relating to the frequency
converter. Danfoss do this by means of a manufacturer's
declaration.
The low-voltage directive (73/23/EEC)
Frequency converters must be CE labeled in accordance
with the low-voltage directive of January 1, 1997. 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 does not affect the way the appliances work.
The EMC directive came into effect January 1, 1996.
Danfoss CE-labels in accordance with the directive and
issues a declaration of conformity upon request. To carry
out EMC-correct installation, see the instructions in this
Design Guide. In addition, Danfoss specifies which
standards our products comply with. Danfoss offers the
filters presented in the specifications and provide other
types of assistance to ensure the optimum EMC result.
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. Not that the
responsibility for the final EMC properties of the appliance,
system or installation rests with the installer.
2.4.2 What is Covered
The EU "Guidelines on the Application of Council Directive
89/336/EEC" outline three typical situations of using a
frequency converter. See chapter 2.4.3 Danfoss Frequency
Converter and CE Labeling for EMC coverage and CE
labeling.
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 labeled 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 labeled under the EMC directive. However,
the unit must comply with the basic EMC
requirements of the directive. This is ensured by
