U, V, W Inverter output Connect these terminals to a three-phase squirrel cage motor. -
R1/L11,
S1/L21 Power supply for the control
circuit
Connected to 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).

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.
