circuit
Connected to the AC power supply terminals R/L1 and S/L2. To
retain the fault display and fault output or when using the high power
factor converter (FR-HC, MT-HC) or power regeneration common
converter (FR-CV), remove the jumpers from terminals R/L1 and R1/
L11, and S/L2 and S1/L21 and apply external power to these
terminals.
The power capacity necessary when separate power is supplied from
R1/L11 and S1/L21 differs according to the inverter capacity.

connection
For the FR-F720-02330 (FR-F740-01160) or less, remove the jumper
across terminals P/+ and P1 and connect the DC reactor. (Be sure to
connect the DC reactor supplied with the FR-F720-03160 (FR-F740-
01800) or more.)
When a DC reactor is not connected, the jumper across terminals P/
