(a) Inverter (FR-A802-P)
(b) Converter unit (FR-CC2-P)
(c) Three-phase AC power supply
Molded case circuit breaker (MCCB),
(d) earth leakage circuit breaker (ELB),
or fuse

(e) Magnetic contactor (MC)
(f) Noise filter
(g) Noise filter
(h) Induction motor

Do not use an earth leakage circuit breaker as a circuit breaker which is intended to be installed per converter unit. Doing so may cause
unintended operation of the inverter.

For every magnetic contactor installed for a converter unit in parallel connection, the ON/OFF timing of the magnetic contactors is critical to
supplying power to the converters simultaneously. Otherwise, the converter units may be damaged.
NOTE
• To prevent an electric shock, always earth (ground) the converter unit, the inverter, and the motor.
• Do not install a power factor correction capacitor or surge suppressor or capacitor type filter on the inverter's output side.
Doing so will cause the inverter output shutoff or the capacitor and surge suppressor to be damaged. If any of the above
devices is connected, immediately remove it. When installing a molded case circuit breaker on the output side of the inverter,
contact the manufacturer of the molded case circuit breaker.
• Electromagnetic wave interference
The input/output (main circuit) of the inverter or the converter unit includes high frequency components, which may interfere
with the communication devices (such as AM radios) used near the inverter or the converter unit. In this case, activating the
EMC filter may minimize interference. (Refer to
• For details of options and peripheral devices, refer to the respective Instruction Manual.

Compatible inverters
The table below shows the converter units compatible with the inverters according to the connected motor capacity.
The capacity of all converter units must be the same in a system, and that of all inverters also must be the same.

The life of the inverter and the converter unit is influenced by the
surrounding air temperature.
The surrounding air temperature should be as low as possible within the
permissible range. This must be noted especially when the inverter is
installed in an enclosure.
Incorrect wiring may lead to damage of the inverter and the converter unit.
The control signal lines must be kept fully away from the main circuit lines
to protect them from noise.
The built-in EMC filter of the converter unit can reduce the noise.
Must be within the permissible power supply specifications of the
converter unit.
Must be selected carefully since an inrush current flows in the converter
unit at power ON.
Install this to ensure safety.
Do not use this to start and stop the inverter. Doing so will shorten the life

of the inverter and the converter unit.
Suppresses the noise radiated from the power supply side of the converter
unit.
Install this to reduce the electromagnetic noise generated from the inverter
or the converter unit. The noise filter is effective in the range from about
0.5 MHz to 5 MHz.
Connect a squirrel-cage induction motor.
