Molded-Case Circuit Breaker / Magnetic Contact
l
GE Power Controls maintenance and service do not apply to damage caused by
following situation:
(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.

Please utilize three-phase squirrel-cage induction motor with appropriate capacity.
l
If a inverter is used to drive more than one motor, the total capacity must be smaller
than the capacity of the inverter. Additional thermal relay must be installed in front of
every 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.
l
Do not install phase advancing capacitor, LC, or RC component between the inverter
and the motor.
