Compliance with EMC Standards

11.1.2.1

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 with the following wiring length (of the shielded
cable) between the inverter and motor under the specified inverter usage conditions.
 FRN001AR1-2U to FRN060AR1-2U
 FRN075AR1S-2U to FRN125AR1S-2U (Lone inverter)
 FRN075AR1S-2U to FRN125AR1S-2U (Combined with filter)
 FRN001AR1-4U to FRN125AR1-4U
 FRN150AR1S-4U to FRN1000AR1S-4U (Lone inverter)
 FRN150AR1S-4U to FRN1000AR1S-4U (Combined with filter)
 FRN001AR1-5U to FRN150AR1-5U
 FRN200AR1S-5U to FRN300AR1S-5U (Lone inverter)

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 clamp 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) FRN007AR1■-2U to FRN060AR1■-2U and FRN015AR1■-4U to FRN125AR1■-4U, be sure to
pass the main circuit power input lines of the inverter through a ferrite core in wiring.
For 575V series, ferrite core is not required.
For wiring of the inverter main circuit power input lines, refer to Chapter 5, Section 5.1.2.1

"(3) Wiring of main circuit power lines."
3) Connect the grounding wires to the grounding terminals without passing them through a ferrite
core.
