2.3.8 Instructions for compliance with the European standards
(Only the 200V and 400V classes comply. 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 does not function independently. It 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 themselves. (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.
We understand that the transistorized inverters themselves 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 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
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.
( 2 ) Low Voltage Directive
1) Our view of transistorized inverters for the Low Voltage Directive
Transistorized inverters are covered by the Low Voltage Directive.
We have self-confirmed our inverters as products compliant to the Low Voltage
Directive and place the CE mark on the inverters.
