(The products conforming to the Low Voltage Directive carry the CE mark.)

1) Our view of transistorized inverters for the EMC Directive

A transistorized inverter is a component designed for installation in a control box and for use with the

other equipment to control the equipment/device. Therefore, we understand that the EMC Directive

does not apply directly to transistorized inverters. For this reason, we do not place the CE mark on the

transistorized inverters. (The CE mark is placed on inverters in accordance with the Low Voltage

Directive.) The European power drive manufacturers' organization (CEMEP) also holds this point of

view.

2) Compliance

We understand that the transistorized inverters are not covered directly by the EMC Directive.

However, the EMC Directive applies to machines/equipment into which transistorized inverters have

been incorporated, and these machines and equipment must carry the CE marks. Hence, we prepared

the European Standard-compliant noise filters and the technical information "EMC Installation

Guidelines" (information number BCN-A21041-202) so that machines and equipment incorporating

transistorized inverters may conform to the EMC Directive more easily.

3) Excerpts from the installation method

It is recommended to mainly use the following methods to install an inverter:

* Use the inverter with an European Standard-compliant noise filter.

* For wiring between the inverter and motor, use shielded cables or run them in a metal piping and 

earth (ground) the cables on the inverter and motor sides with the shortest possible distance.

* Insert a line noise filter and ferrite core into the power and control lines as required.

Full information including the European Standard-compliant noise filter specifications are written in the

technical information "EMC Installation Guidelines" (information number BCN-A21041-202).
