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, surge suppressor, or capacitor type filter on the inverter's output side. Doing
so will cause the inverter shut off or damage the capacitor or surge suppressor. 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. To minimize interference,
enabling the built-in EMC filter or installing an external EMC filters is effective. (Refer to
.)
• For details of options and peripheral devices, refer to the respective Instruction Manual.

(a)
Inverter (FR-A872)
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 and the converter unit are
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.
(b)
Converter unit (FR-CC2-N)
(c)
Three-phase AC power supply
Must be within the permissible power supply specifications of the converter
unit.
(d)
Molded case circuit breaker (MCCB),
earth leakage circuit breaker (ELB), or
fuse
Must be selected carefully since an inrush current flows in the converter
unit at power ON.
(e)
Magnetic contactor (MC)
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.
(f)
Noise filter
Suppresses the noise radiated from the power supply side of the converter
unit.
(g)
Noise filter
Install this to reduce the electromagnetic noise generated from the inverter
and the converter unit. The noise filter is effective in the range from about
0.5 to 5 MHz.
(h)
Induction motor
Connect a squirrel-cage induction motor.
