NOTE
• For 12-phase rectification, the FR-A8CW (wire connection attachment) is required. For 12-phase rectification and the
installation method of the FR-A8CW, refer to the Option Installation Manual.
Terminal function description
Connect a three-phase squirrel-cage 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 connected to terminals R1/L11
and S1/L21, the required power capacity is 80 VA.
Connect the converter unit (FR-CC2).
For earthing (grounding) the inverter chassis. Be sure to earth (ground)
the inverter.
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 apply external
power to these terminals.
When using a separate power supply connected to terminals R1/L11
and S1/L21, the required power capacity is 80 VA.
Connected to the inverter terminals P/+ and N/-.
For earthing (grounding) the converter unit chassis. This product must
be earthed (grounded).
