*1: This part shows the wiring size with using the Lug terminal.
The Lug terminals are an option.
*2: UL output current is different from unit rating output current.
*3: The value of the UL rated output current is applicable when the carrier frequency (EH) is less than the value
shown in the table.
*4: The cables used must be 75°C copper cables within 40°C ambient temperature.
9.2.4 Caution as to the protection of motors from overload

When using the inverter’s thermal protection function to protect the motor from overload, read the instruction manual
included with the inverter carefully and set parameters according to the specifications of the motor used.
When using the inverter to control the operation of multiple motors, install an overload relay for each individual motor.
