Peripheral devices

Check the motor capacity of the inverter you purchased. Appropriate peripheral devices must be selected according to
the capacity. Refer to the following list and prepare appropriate peripheral devices:

*1 Selections for use of the Mitsubishi explosion-proof motor with power supply voltage of 200VAC 50Hz.
*2 Select the MCCB according to the inverter power supply capacity.
Install one MCCB per inverter.
*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, select the MC with class AC-3 rated current for the motor rated current.
*4 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.
