

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 that is suitable for branch circuit protection. (Refer to the FREQROL-CS80 Instructions and Cautions for

Use of Inverters.)



The matrix shows the magnetic contactor selected according to the standards of Japan Electrical Manufacturers'

Association (JEM standards) for 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 for the inverter input current according to the rated current against JEM 1038

standards for AC-3 class. When installing an MC at the inverter output line to switch to the commercial-power supply operation while running a general-

purpose motor, select an MC for the rated motor current according to the rated current against JEM 1038 standards for AC-3 class.



When using a single-phase power input model, terminals are R/L1 and S/L2.



It is the gauge of a cable with the continuous maximum permissible temperature of 75°C (HIV cable (600 V grade heat-resistant PVC insulated wire), etc.).

It assumes a surrounding air temperature of 50°C or lower and the wiring distance of 20 m or shorter.



The power factor may be slightly lower.

NOTE

• When the inverter capacity is larger than the motor capacity, select an MCCB and a magnetic contactor according to the inverter model, and

select cables and reactors according to the motor output.

• When the breaker on the inverter's input side trips, check for the wiring fault (short circuit), damage to internal parts of the inverter etc. The

cause of the output shutoff must be identified and removed before turning ON the power of the breaker.
