NOTE
y
To prevent a malfunction caused by noise, separate the signal cables more than 10cm (3.93inch) from the power cables.
Also separate the main circuit wire of the input side and the output side.
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.
y
The output of the single-phase power input model is three-phase 200V.

*8 Brake resistor (FR-ABR, MRS type, 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-D720-008 and 014, FR-D720S-
008 and 014, FR-D710W-008 and 014.)
