OUTLINE
1.2.1 Peripheral devices
Check the inverter model 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.

Assumes the power supply voltage is for a dedicated IPM motor or of a Mitsubishi 50Hz 4-pole standard motor.

 Select an MCCB according to the power supply capacity.
 Install one MCCB per inverter.

For the use in the United States or Canada, select a UL and cUL certified fuse with Class T fuse equivalent cut-off
speed or faster with the appropriate rating for branch circuit protection. Alternatively, select a UL489 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 stop during motor driving, the electrical durability is 25 times.
If using an MC for emergency stop during motor driving, select an MC by 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 by regarding
the rated motor current as JEM1038-AC-3 class rated current.

NOTE

When the inverter capacity is larger than the motor capacity, select an MCCB and a magnetic contactor according to the inverter model,
and cable and reactor according to the motor output.

When the breaker on the inverter input 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.
