9.1Compliance with CE Marking

9.1.1Abstract

In Europe, EMC directive is enforced starting 1st Jan. of 1996, and Low Voltage Directive starting 1st Jan. of 1997. The display of CE mark that demonstrates that products imported to European Union conform to these directives is required. Inverter itself cannot function alone, but is de-signed as a component in order to control machines or equipment which includes that inverter installed in a cubicle. Therefore the conformance to EMC directive is not required on inverter it-self. But since the object of the Low Voltage directive is equipment that is designed to be used with rated voltage of 50 to 1,000 VAC or 75 to 1,500 VDC, CE should be marked on inverter as to the Low Voltage directive.

But CE has to be marked on the final product installing inverters, that conforms to the EMC directive and the Low Voltage directive. And the product also may conform to Machine directive. The user that makes the final products have to take the responsibility for Marking of CE. For that reason, we recommend installation for Low Voltage directive and measurement for EMC directive, so that the products including our inverter should conform to the EMC and Low Voltage directive.

TOSHIBA carried out Approval testing and confirmation testing on representative models under the circumstances based on installation and measurement so that our products should conform to each directive. But we cannot confirm the conformance of the user’s products to the EMC directive. Since 9 EMC environment changes according to the construction of the cubicle and the relation of other installed electric equipment and the condition of wiring and installation, please confirm the conformance to the EMC directive for the final products on your side.

9.1.2EMC directive

An inverter itself is not an object of CE marking.

A machine which consists of an inverter and a motor is an object of CE marking.

The EMC directive includes the emission section and the immunity section. VF-NC1 can conform to EMC directive by means of installing the recommended EMI noise filter to the input side, and wiring properly.

→Emission: Emission of electromagnetic wave and electromagnetic interference

→Immunity: Resistance to electromagnetic interference

[EMC directive] 89/336/EEC
