R/L1,
S/L2,
T/L3
AC power input
Connect these terminals to the commercial power supply.
Do not connect anything to these terminals when using
the high power factor converter (FR-HC2) or the power
regeneration common converter (FR-CV).
—
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, or to use a high
power factor converter (FR-HC2) or a power regeneration
common converter (FR-CV), 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-F820-00630(15K) or lower, FR-F840-00380(18.5K) or
lower: 60 VA
FR-F820-00770(18.5K) or higher, FR-F840-00470(22K) or
higher: 80 VA

P/+, N/- Brake unit connection Connect the brake unit (FR-BU2, FR-BU, BU), power
regeneration common converter (FR-CV), power
regeneration converter (MT-RC), high power factor
converter (FR-HC2), or DC power supply (under DC feeding
mode).
When connecting multiple inverters, FR-F820-00770(18.5K)
to 01250(30K) or FR-F840-00470(22K) to 01800(75K), in
parallel using the FR-CV, or FR-HC2, always use either of the
terminal P/+ or P3 for the connection. (Do not use the
terminals P/+ and P3 together.)
Do not connect the DC power supply between terminals
P3 and N/–. Use terminals P/+ and N/– for DC feeding.

P/+, P1
DC reactor connection
FR-F820-02330(55K) or lower
FR-F840-01160(55K) 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-F820-03160(75K) or higher
FR-F840-01800(75K) or higher
Always connect a DC reactor, which is available as an
option.
PR, PX
Do not use terminals PX and PR. The terminal PX is equipped in the FR-F820-00490(11K) or lower
and the FR-F840-00250(11K) or lower. The terminal PR is equipped in the FR-F820-01250(30K) or
lower and the FR-F840-01800(75K) or lower.
Earth (ground)
For earthing (grounding) the inverter chassis. This must be
earthed (grounded).
