*1 Selections for use of the Mitsubishi 4-pole standard motor with power supply voltage of 200VAC 50Hz.
*2 Select the MCCB according to the power supply capacity.
Install one MCCB per inverter.
For using commercial-power supply operation, select a breaker with capacity which allows the motor to be
directly power supplied.
For installation in the United States, Class RK5, Class J, Class CC, Class L, Class T or any faster acting
fuses or UL 489 Molded Case Circuit Breaker (MCCB) must be provided, in accordance with the National
Electrical Code and any applicable local codes.
For installation in Canada, Class RK5, Class J, Class CC, Class L, Class T or any faster acting fuses or UL
489 Molded Case Circuit Breaker (MCCB) must be provided, in accordance with the Canada Electrical
Code and any applicable provincial codes. (Refer to page 169.)
*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.
CAUTION
⋅ When the inverter capacity is larger than the motor capacity, select an MCCB and a magnetic contactor according to the
inverter model, and select cable and reactor according to the motor output.
⋅ 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.
