Terminal function description
Connect these terminals to a three-phase squirrel cage motor or a PM motor. -
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
across terminals R1/L11 and S1/L21, and supply external power to these
terminals.
The power capacity necessary when separate power is supplied from
terminals 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. Be sure to earth (ground) the
inverter.
Terminal function description
Connect these terminals to the commercial power supply. (When the FR-CC2
converter is connected to the12-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. Be sure to earth (ground)
the converter.
