Chapter 9 CONFORMITY WITH STANDARDS
9.1 Compliance with UL Standards and Canadian Standards (cUL certification)
9.1.1 General
Originally, the UL standards were established by Underwriters Laboratories, Inc. as private criteria for
inspections/investigations pertaining to fire/accident insurance in the USA. Later, these standards were authorized as the
official standards to protect operators, service personnel and the general populace from fires and other accidents in the USA.
cUL certification means that UL has given certification for products to clear CSA Standards. cUL certified products are
equivalent to those compliant with CSA Standards.
9.1.2 Considerations when using FRENIC-MEGA in systems to be certified by UL and cUL
If you want to use the FRENIC-MEGA series of inverters as a part of UL Standards or CSA Standards (cUL certified)
certified product, refer to the related guidelines described on pages ix to xii.
9.2 Compliance with European Standards
The CE marking on Fuji products indicates that they comply with the essential requirements of the Electromagnetic
Compatibility (EMC) Directive 2004/108/EC and Low Voltage Directive 2006/95/EC which are issued by the Council of the
European Communities
The products comply with the following standards
Basic type EMC filter built-in type
EMC Directives
Depends upon a filter dedicated to
Fuji inverters*
EN61800-3 : 2004
Immunity : Second environment (Industrial)
Emission : Category C3
Low Voltage Directive EN61800-5-1: 2003
Safety Standard EN954-1: Category 3
* If connected with an external EMC filter dedicated to Fuji inverters, the basic type of inverters that bear a CE marking but
have no built-in EMC filter becomes compliant with these EMC Directives.
CAUTION
The EMC filter built-in type of the FRENIC-MEGA inverters is categorized as "Category C3" of the EN61800-3. It is not
designed for use in a domestic environment. It may interfere with the operations of home appliances or office equipment due
to noise emitted from it.
9.3 Compliance with EMC Standards
9.3.1 General
The CE marking on inverters does not ensure that the entire equipment including our CE-marked products is compliant with
the EMC Directive. Therefore, CE marking for the equipment shall be the responsibility of the equipment manufacturer. For
this reason, Fuji’s CE mark is indicated under the condition that the product shall be used within equipment meeting all
requirements for the relevant Directives. Instrumentation of such equipment shall be the responsibility of the equipment
manufacturer.
Generally, machinery or equipment includes not only our products but other devices as well. Manufacturers, therefore, shall
design the whole system to be compliant with the relevant Directives.
In addition, to satisfy the requirements noted above, use the EMC filter built-in type of inverters or the combination of the
basic type of inverters that have no built-in EMC filter and an external filter (option) dedicated to Fuji inverters. In either case,
mount inverters in accordance with the installation procedure given below. To ensure the compliance, it is recommended that
inverters be mounted in a metal panel.
Our EMC compliance test is performed under the following conditions.
Wiring length (of the shielded cable) between the inverter (EMC filter built-in type) and motor: 5m
To use Fuji inverters in combination with a PWM converter, the basic type of inverters having no built-in EMC
filter should be used. Use of an EMC filter built-in type may increase heat of capacitors in the inverter, resulting in
a break. In addition, the effect of the EMC filter can no longer be expected.
