WARNING
The Adjustable frequency drive DC link capacitors remain
charged after power has been disconnected. To avoid an
electrical shock hazard, disconnect the Adjustable
frequency drive from line power before carrying out
maintenance. Wait at least as long as follows before doing
service on the Adjustable frequency drive:

2.1.2 Disposal Instructions
Equipment containing electrical
components may not be disposed of
together with domestic waste.
It must be separately collected with
electrical and electronic waste according
to local and currently valid legislation.

2.2 CE labeling
2.2.1 CE Conformity and Labeling
What is CE Conformity and Labeling?
The purpose of CE labeling is to avoid technical trade
obstacles within the 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 specifi-
cations or quality of the product. Adjustable frequency
drives are regulated by three EU directives:
The machinery directive (2006/42/EC)
Adjustable frequency drives with the integrated safety
function are now falling under the Machinery Directive.
Danfoss uses CE labels in accordance with the directive
and will issue a declaration of conformity upon request.
Adjustable frequency drives without the safety function do
not fall under the machinery directive. However, if a
Adjustable frequency drive is supplied for use in a
machine, we provide information on safety aspects relating
to the Adjustable frequency drive.
The low-voltage directive (2006/95/EC)
Adjustable frequency drives 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 (2004/108/EC)
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 on 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, we specify which standards our
products comply with. We offer the filters presented in the
specifications and provide other types of assistance to
ensure the optimum EMC result.
The Adjustable frequency drive is most often 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.
2.2.2 What Is Covered
The EU "
Guidelines on the Application of Council Directive
2004/108/EC
" outline three typical situations of using a
Adjustable frequency drive. See below for EMC coverage
and CE labeling.
1.
The Adjustable frequency drive is sold directly to
the end-consumer. The Adjustable frequency
drive is for example sold to a DIY market. The
end-consumer is a layman. He installs the
Adjustable frequency drive himself for use with a
hobby machine, a kitchen appliance, etc. For such
applications, the Adjustable frequency drive must
