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.

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 below for EMC coverage

and CE labelling.

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 labelled in accordance with the EMC directive.

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 labelled under

the EMC directive. However, the unit must comply with the basic EMC requirements of the directive. This is ensured by using components, appliances,

and systems that are CE labelled under the EMC directive.

The frequency converter is sold as part of a complete system. The system is being marketed as complete and could e.g. be an air-conditioning system.

The complete system must be CE labelled in accordance with the EMC directive. The manufacturer can ensure CE labelling under the EMC directive either

by using CE labelled components or by testing the EMC of the system. If he chooses to use only CE labelled components, he does not have to test the

entire system.

2.4.3 GE Frequency Converter and CE Labelling

CE labelling is a positive feature when used for its original purpose, i.e. to facilitate trade within the EU and EFTA.

However, CE labelling may cover many different specifications. Thus, you have to check what a given CE label specifically covers.

The covered specifications can be very different and a CE label may therefore give the installer a false feeling of security when using a frequency converter as a

component in a system or an appliance.

GE CE labels the frequency converters in accordance with the low-voltage directive. This means that if the frequency converter is installed correctly, we guarantee

compliance with the low-voltage directive. GE issuesWe issue a declaration of conformity that confirms our CE labelling in accordance with the low-voltage

directive.

The CE label also applies to the EMC directive provided that the instructions for EMC-correct installation and filtering are followed. On this basis, a declaration of

conformity in accordance with the EMC directive is issued.

The Design Guide offers detailed instructions for installation to ensure EMC-correct installation. Furthermore, GE specifies which our different products comply

with.

GE provides other types of assistance that can help you obtain the best EMC result.

2.4.4 Compliance with EMC Directive 89/336/EEC

As mentioned, the frequency converter is mostly 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. As an aid to the

installer, GE has prepared EMC installation guidelines for the Power Drive system. The standards and test levels stated for Power Drive systems are complied with,

provided that the EMC-correct instructions for installation are followed, see the section EMC Immunity.

The frequency converter has been designed to meet the IEC/EN 60068-2-3 standard, EN 50178 pkt. 9.4.2.2 at 50°C.
