Terminal function description
Connect these terminals to a three-phase squirrel cage motor or a PM motor. -
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.
Connect the converter unit (FR-CC2), brake unit (FR-BU2), or high power
factor converter (FR-HC2).
For earthing (grounding) the inverter chassis. This must be earthed
(grounded).
Terminal function description
Connect these terminals to the commercial power supply. (When the
converter unit is connected to the 12-phase rectifier power transformer, refer
to the Instruction Manual of the FR-CC2.)
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.
Connect to terminals P/+ and N/- of the inverter.
For earthing (grounding) the converter unit chassis. This must be earthed
(grounded).
