Peripheral devices
Check the model of the inverter you purchased. Appropriate peripheral devices must be selected according to the capacity.
Refer to the table below to prepare appropriate peripheral devices.
NOTE
• When the inverter capacity is larger than the motor capacity, select an MCCB and a magnetic contactor according to the
inverter model, and select cables and reactors according to the motor output.
• When the breaker on the inverter's input side trips, check for the wiring fault (short circuit), damage to internal parts of the
inverter etc. The cause of the trip must be identified and removed before turning ON the power of the breaker.

Assumes the use of a Mitsubishi standard 4-pole motor with the power supply voltage of 400 VAC 50 Hz.
Select an MCCB according to the power supply capacity.
Install one MCCB per inverter.
For the use in the United States or Canada, refer to
, and select an appropriate fuse or molded
case circuit breaker (MCCB).
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 motor driving, select an MC regarding the inverter input side current as JEM1038-AC-3 class rated
current. When providing an MC on the inverter output side for switching to commercial power supply during general-purpose motor operation,
select an MC regarding the rated motor current as JEM1038-AC-3 class rated current.
