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.
EMC certification testing is performed using the following wiring distances between the inverter and
motor (shielded wire):
・FRN0.75AR1 -2 to FRN45AR1 -2
FRN001AR1 -2U to FRN060AR1 -2U
to FRN90AR1S-2
・FRN55AR1S-2
FRN075AR1S-2U to FRN125AR1S-2U (inverter alone)
to FRN90AR1S-2
・FRN55AR1S-2
FRN075AR1S-2U to FRN125AR1S-2U (with filter)
・FRN0.75AR1 -4 to FRN90AR1 -4
FRN001AR1 -4U to FRN125AR1 -4U
to FRN710AR1S-4
・FRN110AR1S-4
FRN150AR1S-4U to FRN1000AR1S-4U(inverter alone)
to FRN710AR1S-4
・FRN110AR1S-4
FRN150AR1S-4U to FRN1000AR1S-4U(with filter)

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 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) For the inverters of 200V class series 5.5 to 45 kW (7 to 60HP) and 400V ones of 11 to 90 kW (15 to
125HP), be sure to pass the main circuit power input lines of the inverter through a ferrite core in wiring.
For wiring of the main circuit power input lines, refer to Chapter 2, Section 2.2.1 "(4) Wiring the main
circuit power input wires."
3) Connect the grounding wires to the grounding terminals without passing them through the ferrite core.
Grounding terminal
4) For connection to inverter's control terminals and for connection of the RS-485 communication signal cable,
use shielded wires. As with the motor, clamp the shields firmly to the specified point or the grounded metal
plate inside the inverter.
