INSTALLATION AND WIRING
control
When a multi-wound motor is connected under Real sensorless vector control or Vector control

Select an MCCB according to the power supply capacity.
Install one MCCB per converter circuit in the converter unit.
For the use in the United States or Canada, provide appropriate fuses in accordance with any applicable local codes.

The 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 stops during motor driving, the electrical durability is 25 times.
When using an MC for emergency stop during driving the motor, select the MC with JEM 1038-AC-3 class rated current for the converter unit
input current. When providing an MC on the inverter output side for switching to commercial power supply during general-purpose motor
operation, select the MC with JEM 1038-AC-3 class rated current for the rated motor current.
• Option 3
To connect the equipment to the output side of the 12-phase rectifier transformer after branching, refer to the following table
and prepare appropriate equipment.
When a single wound motor or a multi-wound motor is connected under V/F control or Advanced magnetic flux vector
control
When a multi-wound motor is connected under Real sensorless vector control or Vector control
