INSTALLATION AND WIRING
Terminal function description
Connect these terminals to a three-phase squirrel cage motor or an 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.
When using a separate power supply from R1/L11 and S1/L21, the
necessary power capacity of the separate power supply is 80 VA.
Connect the converter unit (FR-CC2).
For earthing (grounding) the inverter chassis. This must be earthed
(grounded).
Terminal function description
Connect these terminals to the commercial power supply.
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.
When using a separate power supply from R1/L11 and S1/L21, the
necessary power capacity of the separate power supply is 80 VA.
Connect to terminals P/+ and N/- of the inverter.
For earthing (grounding) the converter unit chassis. This must be earthed
(grounded).
