T/L3
AC power input Connect these terminals to the commercial power supply. —
U, V, W Inverter output Connect these terminals to a three-phase squirrel cage motor or a PM
motor.

R1/L11,
S1/L21
Power supply for the control
circuit
Connected to the AC power supply terminals R/L1 and S/L2. To retain the
fault display and fault output, remove the jumpers across terminals R/L1
and R1/L11 and across S/L2 and S1/L21, and supply 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.
FR-F860-00170 or lower
60 VA
FR-F860-00320 or higher
80 VA

P/+, N/- DC terminal Connect these terminals to the DC power supply for DC feeding. —
P/+, P1 DC reactor connection
FR-F860-00680 or lower
Remove the jumper across terminals P/+ and P1, and connect a DC
reactor.
When a DC reactor is not connected, the jumper across terminals P/+ and
P1 should not be removed.

DC reactor connection
FR-F860-01080 or higher
Always connect a DC reactor. (The jumper is not installed for the FR-F860-
01440 or higher.)
P3, PR Do not use terminals P3 and PR. The terminal PR is equipped in the FR-F860-01080 or lower. The terminal
P3 is equipped in the FR-F860-00027 to 00170 and FR-F860-00450 to 01080.
