Chapter 8 CONFORMITY WITH STANDARDS
8.1

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
Low Voltage Directive EN61800-5-1: 2007
EN61800-3 : 2004
EMC Directives
Immunity : Second environment (Industrial)
Emission : Category C2
8.2

Conformity to the Lower Voltage Directive in the EU

To use Fuji inverters as a product conforming to the Lower Voltage Directive in the EU, refer to guidelines given
on pages vi and vii.
8.3

Compliance with EMC Standards

8.3.1 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.
Our EMC compliance test is performed under the following conditions.
Wiring length (of the shielded cable) between the inverter and motor: 75 m
For detailed restrictions by the wiring length and carrier frequency setting, refer to the User's
Manual.

8.3.2 Recommended installation procedure

To make the machinery or equipment fully compliant with the EMC Directive, have certified technicians wire the
motor and inverter in strict accordance with the procedure given below.
1) Use shielded wires for the motor cable and route the cable as short as possible. Firmly camp the shield to
the specified point or the grounded metal plate inside the inverter. Further, connect the shielding layer
electrically to the grounding terminal of the motor.
2) For the inverters of 11 to 37 kW, be sure to pass the main circuit power input lines of the inverter through a
ferrite core in wiring.
3) Connect the grounding wires to the grounding terminals without passing them through a ferrite core.
