INSTALLATION AND WIRING
 Selecting the breaker/magnetic contactor 6-phase transformer
Check the model of the inverter and the converter unit you purchased. Appropriate peripheral devices must be selected
according to the capacity.
Refer to the table below to prepare appropriate peripheral devices.
• One circuit breaker and one magnetic contactor in total in a system
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
• One circuit breaker and one magnetic contactor per converter unit
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

Select an MCCB according to the power supply capacity.
Install one MCCB per converter unit. (For the use in the United States or Canada, refer to
page 176 to select an appropriate fuse or molded case
circuit breaker (MCCB).)

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.
If using an MC for emergency stop during driving the motor, select an MC regarding the converter unit input side current as JEM1038-AC-3 class
rated current. When providing an MC to use the commercial power supply during general-purpose motor operation, select an MC regarding the
rated motor current as JEM1038-AC-3 class rated current.

An air circuit breaker (ACB) is also applicable in a system in which a 2000 A breaker or higher is applicable.
