zThree-phase 200V power input

zThree-phase 400V power input

NOTE

To prevent a malfunction caused by noise, separate the signal cables more than 10cm (3.93inch) from the power cables.

y After wiring, wire offcuts must not be left in the inverter.

Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter clean. When drilling mounting holes

in an enclosure etc., take care not to allow chips and other foreign matter to enter the inverter.

*7 Brake resistor (FR-ABR, MRS, MYS type)

Install a thermal relay to prevent an

overheat and burnout of the brake resistor.

(The brake resistor can not be connected

to the FR-E720-008 and 015.)
