3.3.2 Contactor and Circuit Breaker specification and wiring.
Molded-case circuit breaker/magnetic contactor
 Teco bears no responsibility 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.

 Use three-phase squirrel cage induction motor with capacity suitable for the inverter.
 If one inverter is driving several motors, the total current of all motors running simultaneously
must be less than the rated current of the inverter, and each motor has to be equipped with a
proper thermal relay.
 Do not add capacitive components, such as a phase capacitors, LC or RC, between the inverter
and the motor.
