Appendix 1 Instructions for Compliance with the
(The products conforming to the Low Voltage Directive carry the CE mark.)
(1) EMC Directive
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) Outline of installation method
Install an inverter using the following methods:
* 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 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" (BCN-A21041-202). Please contact your sales representative.
