Safety and Conformity

2 Safety and Conformity

2.1 Safety Precautions

Frequency converters contain high-voltage components
and have the potential for fatal injury if handled
improperly. Only trained technicians should install and
operate the equipment. No repair work should be
attempted without first removing power from the
frequency converter and waiting the designated amount of
time for stored electrical energy to dissipate.
Strict adherence to safety precautions and notices is
mandatory for safe operation of the frequency converter.

2.2 Caution

WARNING
DISCHARGE TIME
Frequency converters contain DC-link capacitors that can
remain charged even when the frequency converter is
not powered. To avoid electrical hazards, disconnect the
following:
•
AC mains
•
Permanent magnet type motors
•
Remote DC-link power supplies, including
battery backups, UPS and DC-link connections
to other frequency converters
Wait for the capacitors to fully discharge before
performing any service or repair work. The amount of
wait time is listed in the Capacitor Discharge Time table.
Failure to wait the specified time after power has been
removed before starting service or repair could result in
death or serious injury.

2.3 CE Labelling

2.3.1 CE Conformity and Labelling
Machinery Directive (2006/42/EC)
Frequency converters do 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.
What is CE Conformity and Labelling?
The purpose of CE labelling 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 two EU
directives:
Low-Voltage Directive (2006/95/EC)
Frequency converters must be CE labelled 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.
EMC Directive (2004/108/EC)
EMC is short for electromagnetic compatibility. The
presence of electromagnetic compatibility means that the

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 7.8 EMC-Correct Instal-
lation. In addition, we specify which standards our
products comply with. Danfossoffer 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 trade
professionals as a complex component forming part of a
larger appliance, system or installation. It must be noted

Do not dispose of equipment containing
electrical components together with
domestic waste.
Collect it separately in accordance with
local and currently valid legislation.
