U, V, W

Inverter output

Connect these terminals to a three-phase squirrel cage motor or an PM 
motor.

-

R1/L11,
S1/L21

Power supply for the control 
circuit

Connected to the terminals P/+ and N/-. To retain the fault display and fault 
output, or to use the converter unit (FR-CC2), remove the jumpers installed in 
terminals R1/L11 and S1/L21, and apply external power supply to these 
terminals.
The power capacity necessary when separate power is supplied from R1/L11 
and S1/L21 is 80 VA.

P/+, N/-

Converter unit connection

Connect the converter unit (FR-CC2), brake unit (FR-BU2), or high power 
factor converter (FR-HC2).

Earth (ground)

For earthing (grounding) the inverter chassis. This must be earthed 
(grounded).

R/L1,
S/L2,
T/L3

AC power input

Connect these terminals to the commercial power supply.

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 is 80 VA.

P/+, N/-

Inverter connection

Connect to terminals P/+ and N/- of the inverter.

Earth (ground)

For earthing (grounding) the converter unit chassis. This must be earthed 
(grounded).
