2.3.7 Instructions for compliance with the European standards
(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, but the machines/equipment into which they have been
incorporated are covered by the EMC Directive and 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
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.
(2) Low Voltage Directive
1) Our view of transistorized inverters for the Low Voltage Directive
Transistorized inverters are covered by the Low Voltage Directive.
2) Compliance
We have self-confirmed our inverters as products compliant to the Low Voltage
Directive and place the CE mark on the inverters.
