9. Taking measures to satisfy the CE / UL / CSA

9.1

Compliance with CE Marking

9.1.1 Abstract

In Europe, EMC directive is enforced starting 1

st

Jan. of 1996, and Low Voltage Directive starting 1

st

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
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.

9.1.2 EMC 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
