Ce Labelling - Danfoss VLT HVAC Drive FC 100 Series Design Manual

2. Introduction to VLT HVAC Drive
2.1.2. Caution

The frequency converter DC link capacitors remain charged after power has been disconnected. To avoid an electrical shock hazard, disconnect the
frequency converter from the mains before carrying out maintenance. Wait at least as follows before doing service on the frequency converter:
Voltage
200 - 240 V
380 - 480 V
525 - 600 V

2.2. CE labelling

2.2.1. CE Conformity and Labelling
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 three 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, we provide information on safety aspects
relating to the frequency converter. We do this by means of a manufacturer's declaration.
The low-voltage directive (73/23/EEC)
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.
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, 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 frequency converter 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.
