Approvals and Certification...
3 Approvals and Certifications
Frequency converters are designed in compliance with the
directives described in this section.
Table 3.1 Approvals
3.1 CE Mark
The CE mark (Communauté européenne) indicates that the
product manufacturer conforms to all applicable EU
directives. The EU directives applicable to the design and
manufacture of frequency converters are the Low Voltage
Directive, the EMC Directive, and (for units with an
integrated safety function) the Machinery Directive.
The CE mark is intended to eliminate technical barriers to
free trade between the EC and EFTA states inside the ECU.
The CE mark does not regulate the quality of the product.
Technical specifications cannot be deduced from the CE
mark.
3.2 Low Voltage Directive
Frequency converters are classified as electronic
components and must be CE labeled in accordance with
the 2014/35/EU Low Voltage Directive. The directive
applies to all electrical equipment in the 50–1000 V AC
and the 75–1600 V DC voltage ranges.
The directive mandates that the equipment design must
ensure the safety and health of people and livestock are
not endangered and the preservation of material worth so
long as the equipment is properly installed, maintained,
and used as intended. Danfoss CE-labels comply with the
Low Voltage Directive and provide a declaration of
conformity on request.
3.3 EMC Directive
Electromagnetic compatibility (EMC) means that electro-
magnetic interference between apparatus does not hinder
their performance. The basic protection requirement of the
EMC Directive 2014/30/EU states that devices that generate
electromagnetic interference (EMI) or whose operation
could be affected by EMI must be designed to limit the
generation of electromagnetic interference and shall have
a suitable degree of immunity to EMI when properly
installed, maintained, and used as intended.

Design Guide
A frequency converter can be used as standalone device or
as part of a more complex installation. Devices used as
standalone or as part of a system must bear the CE mark.
Systems must not be CE marked but must comply with the
basic protection requirements of the EMC directive.
3.4 Machinery Directive
Frequency converters are classified as electronic
components subject to the Low Voltage Directive, however
frequency converters with an integrated safety function
must comply with the Machinery Directive 2006/42/EC.
Frequency converters without safety function do not fall
under the Machinery Directive. If a frequency converter is
integrated into machinery system, Danfoss provides
information on safety aspects relating to the frequency
converter.
Machinery Directive 2006/42/EC covers a machine
consisting of an aggregate of interconnected components
or devices of which at least 1 is capable of mechanical
movement. The directive mandates that the equipment
design must ensure the safety and health of people and
livestock are not endangered and the preservation of
material worth so long as the equipment is properly
installed, maintained, and used as intended.
When frequency converters are used in machines with at
least 1 moving part, the machine manufacturer must
provide declaration stating compliance with all relevant
statutes and safety measures. Danfoss CE-labels comply
with the Machinery Directive for frequency converters with
an integrated safety function and provide a declaration of
conformity on request.
3.5 UL Compliance
To ensure that the frequency converter meets the UL
safety requirements, see chapter 8.3 Electrical Requirements
for Certifications and Approvals.
3.6 RCM Mark Compliance
The RCM Mark label indicates compliance with the
applicable technical standards for Electromagnetic Compat-
ibility (EMC). An RCM Mark label is required for placing
electrical and electronic devices on the market in Australia
and New Zealand. The RCM Mark regulatory arrangements
only deal with conducted and radiated emission. For
frequency converters, the emission limits specified in
EN/IEC 61800-3 apply. A declaration of conformity can be
provided on request.
