Inverter and peripheral devices
(c) Three-phase AC power supply
(d) Molded case
circuit breaker
(MCCB) or earth

breaker (ELB),
fuse
(e) Magnetic
contactor
(MC)
(f) Noise filter
: Install these options as required.
NOTE
• To prevent an electric shock, always earth (ground) the motor and inverter.
• 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 includes high frequency components, which may interfere with the
communication devices (such as AM radios) used near the inverter. 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.
