Suitable optional and Wiring Specification
Molded-Case Circuit Breaker / Magnetic Contact
z Warrantee does not apply to damage caused by the following situations:
(1) Damage to the inverter caused by the lack of appropriate molded-case circuit breaker or
when a circuit breaker with too large of capacity is installed between the power supply and
the inverter.
(2) Damage to the inverter caused by the magnetic contact, phase advancing capacitor, or
surge-protector installed between the inverter and the motor.

Use copper conductors only size field wiring based on 80 degrees C wire only.
z Please utilize three-phase squirrel-cage induction motor with appropriate capacity.
z If the inverter is used to drive more than one motor, the total capacity must be smaller
than the capacity of the inverter. Additional thermal overload relays must be installed in
front of each motor. Use the Fn_18 at 1.0 times of the rated value specified on the motor
nameplate at 50Hz, 1.1 times of the rated value specified on the motor nameplate at 60Hz.
z Do not install phase advancing capacitors, LC, or RC component between the inverter and
the motor.
