Peripheral devices

Check the model of the inverter you purchased. Appropriate peripheral devices must be selected according to the capacity.
Refer to the following table to prepare appropriate peripheral devices.
 Molded case circuit breaker / earth leakage circuit breaker
• This is a matrix showing the rated current of the molded case circuit breaker (MCCB) or earth leakage circuit breaker (ELB)
(NF or NV type) according to the selected inverter and rating.

NOTE
• 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.)
• 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.
