Peripheral devices

2.1.2 Peripheral devices
Check the model of the inverter you purchased. Appropriate peripheral devices must be selected ac-
cording to the capacity.
Refer to the table below to prepare appropriate peripheral devices.

Tab. 2-2:
Assumes the use of an IPM motor MM-EFS/MM-THE4 or a Mitsubishi 4-pole standard motor with
the power supply voltage of 200 V AC 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, provide the appropriate UL and cUL listed fuse or UL489
molded case circuit breaker (MCCB) that is suitable for branch circuit protection. (Refer to the
Installation Guideline.)
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 motor driving, select an MC regarding the inverter input
side current as JEM1038-AC-3 class rated current. When using an MC on the inverter output side
for commercial-power supply operation switching using a general-purpose motor, select an MC
regarding the rated motor current as JEM1038-AC-3 class rated current.
