Applicable magnetic contactor and wires
Molded-case circuit breaker/magnetic contactor
z
Our bears no responsibilty to service for failures caused by the following conditions:
(1) A molded-case circuit breaker is not installed, or an improper or overrated breaker is
used, between the power source and the inverter.
(2) A magnetic contactor, a phase capacitor, or a burst absorber is connected between the
inverter and the motor.

z
Use three-phase cage reaction motor with capacity suitable for the inverter.
z
When one inverter is used to drive several motors, the total current of all motors running
simultaneouly must be less than the capacity of the inverter, and each motor has to be
equipped with a proper thermal relay.
z
Do not add capacitive component, such as a phase capacitor, LC, or RC, between the inverter
and the motor.
