Inverter and peripheral devices
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:
200V class
Motor Output
(kW) Applicable Inverter Model

0.4 FR-A720-0.4K
0.75 FR-A720-0.75K
1.5 FR-A720-1.5K
2.2 FR-A720-2.2K
3.7 FR-A720-3.7K
5.5 FR-A720-5.5K

*1 Motor Output (kW) in the above table indicates values when using the Mitsubishi 4-pole standard motor with power supply voltage of 200VAC
50Hz.
*2 Select the MCCB according to the power supply capacity. Install one MCCB per inverter.
For installation in the United States or Canada, select a fuse in accordance with UL, cUL, the National
Electrical Code and any applicable local codes, or use UL 489 Molded Case Circuit Breaker (MCCB).
(Refer to Instruction Manual (basics).)
*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.
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 motor rated current as JEM1038-AC-3 class rated current.
CAUTION
⋅ 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 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.
