Connect to the commercial power supply.
Do not connect anything to these terminals when using the high power factor
converter (FR-HC2) or power regeneration common converter (FR-CV).
Connect a three-phase squirrel-cage motor or a dedicated IPM motor.
Connect a brake resistor (FR-ABR, MRS type, MYS type) across terminals P/+
and PR.
Connect the brake unit (FR-BU2), power regeneration common converter (FR-
CV) or high power factor converter (FR-HC2).
Remove the jumper across terminals P/+ and P1 and connect a DC reactor.
Do not remove the jumper across terminals P/+ and P1 when neither a
Filterpack nor a DC reactor is connected.
For earthing (grounding) the inverter chassis. Must be earthed (grounded).
For earthing (grounding) the Filterpack.
Must be earthed (grounded).
Cable Color
Black
Connect to R/L1, S/L2, and T/L3 of the inverter.
Remove the jumper across terminals P/+ and P1, and connect to
Red
the terminals P/+ and P1 of the inverter.
Green and yellow
Connect to the earth (ground) terminal of the inverter. (Refer to
