*1 Selections for use of the Mitsubishi 4-pole standard motor with power supply voltage of 200VAC/400VAC 50Hz.
*2 Select the MCCB according to the inverter power supply capacity.
Install one MCCB per inverter.
For installations in the United States or Canada, use the appropriate UL and cUL listed class RK5, class T
type fuse or UL489 molded case circuit breaker (MCCB).
(Refer to page 190.)
*3 Magnetic contactor is selected based on the AC-1 class. The electrical durability of magnetic contactor is 500,000 times. When the magnetic
contactor is used for emergency stop during motor driving, the electrical durability is 25 times.
When using the MC for emergency stop during motor driving or using on the motor side during commercial-power supply operation, select the MC
with class AC-3 rated current for the motor rated current.
REMARKS
When the breaker on the inverter primary side trips, check for the wiring fault (short circuit), damage to internal parts of the
inverter, etc. Identify the cause of the trip, then remove the cause and power on the breaker.
