INSTALLATION AND WIRING
2.1.2 Peripheral devices
Selecting the converter unit (FR-CC2-C)
Select the capacity of the FR-CC2-C converter unit according to the connected motor capacity.
The applicable motor capacity indicated is the maximum capacity applicable for use of the 4-pole standard motor.
Selecting the breaker/magnetic contactor
Check the model of the inverter and the converter unit you purchased. Appropriate peripheral devices must be selected
according to the capacity.
Refer to the table below to prepare appropriate peripheral devices.
• When the converter unit capacity is larger than the motor capacity, select an MCCB and a magnetic contactor according to
the converter unit model, and select cables and reactors according to the motor output.
• When the breaker on the converter unit's input side trips, check for the wiring fault (short circuit), damage to internal parts of
the inverter and the converter unit, etc. The cause of the trip must be identified and removed before turning ON the power of
the breaker.

Assumes the use of a 4-pole standard motor with the power supply voltage of 575 VAC 50 Hz.
Select an MCCB according to the power supply capacity.
Install one MCCB per converter.
For the use in the United States or Canada, provide the appropriate UL and cUL listed fuse that
is suitable for branch circuit protection. (Refer to page 83.)
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 driving the motor, select an MC regarding the converter unit 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.
