12.1.2 Compliance with EMC standards
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.

List of EMC-compliant filters
To satisfy the requirements noted above, use inverters in combination with 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.

Recommended installation procedure
To make the machinery or equipment fully compliant with the EMC Directive, have certified technicians wire the
filter stack, the PWM converter, the diode rectifier, the inverter and the motor and in strict accordance with the
procedure described below.
When an EMC-compliant filter (option) is externally used
1) Mount the filter stack, the PWM converter, the diode rectifier, the inverter and the filter on a grounded panel or metal plate. Use
shielded wires for the motor cable and route the cable as short as possible. Firmly clamp the shields to the metal plate to ground
them. Further, connect the shielding layers electrically to the grounding terminal of the motor.
2) For connection to control terminals of the filter stack, the PWM converter, the diode rectifier and the inverter and for connection of
the RS-485 communication signal cable, use shielded wires. As with the motor, clamp the shields firmly to a grounded panel.
