Appendix 2 Instructions for compliance with the European Directives
(1) EMC Directive
1) Our view of transistorized inverters for the EMC Directive
A transistorized inverter is a component designed for installation in an enclosure 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.) European Committee of Manufacturers of Electrical Machines and Power
Electronics(CEMEP) also holds this point of view.
We understand that the general-purpose inverters are not covered directly by the EMC Directive. However, the EMC
Directive applies to machines/equipment into which inverters have been incorporated, and these machines and equipment
must carry the CE marks. EMC Installation Guidelines BCN-A21041-202
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 common mode 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
We have self-confirmed our inverters as products compliant to the Low Voltage Directive (Conforming standard EN 61800-
5-1) and place the CE mark on the inverters.
Outline of instructions
∗ Do not use an earth leakage circuit breaker as an electric shock protector without connecting the equipment to the earth.
Connect the equipment to the earth securely.
∗ Wire the earth (ground) terminal independently. (Do not connect two or more cables to one terminal.)
∗ Use the cable sizes on page 13 under the following conditions.
Ambient Temperature: 40°C maximum
If conditions are different from above, select appropriate wire according to EN60204 ANNEX C TABLE 5.
∗ When tightening the screw, be careful not to damage the threads.
For use as a product compliant with the Low Voltage Directive, use PVC cable on page 13.
∗ Use the moulded case circuit breaker and magnetic contactor which conform to the EN or IEC Standard.
∗ When using an earth leakage circuit breaker, use a residual current operated protective device (RCD) of type B (breaker
which can detect both AC and DC). If not, provide double or reinforced insulation between the inverter and other
equipment, or put a transformer between the main power supply and inverter.
∗ Use the inverter under the conditions of overvoltage category II (usable regardless of the earth (ground) condition of the
power supply), overvoltage category III (usable with the earthed-neutral system power supply, 400V class only) specified
To use the inverter under the conditions of pollution degree 3, install it in the enclosure of IP54 or higher.
