Be sure to connect the DC reactor
Main circuit terminal
supplied with the FR-A720-02880 (FR-
A740-01440) or more.
Control circuit terminal
When using the FR-A720-02150 (FR-
A740-01100) with LD or SLD set,
always use a DC reactor (option).
When a DC reactor is connected to the
FR-A720-02150 (FR-A740-01100) or
less, remove the jumper across P1-P/+.

control circuit separately,
remove the jumper across
R1/L11 and S1/L21.

*6 . It is recommended to use 2W1kΩ
when the frequency setting signal
is changed frequently.
CAUTION
· To prevent a malfunction due to noise, keep the signal cables more than 10cm (3.94inches) away from the power cables.
· 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.
· Set the voltage/current input switch correctly. Different setting may cause a fault, failure or malfunction.
