* For wiring to earth (ground) terminals of FR-D720-5.5K and 7.5K, use the earthing (grounding) cable wiring space (marked with an arrow) to route the wires.
Connect to the commercial power supply.
Keep these terminals open when using the high power factor converter (FR-HC) or
power regeneration common converter (FR-CV).
Connect a three-phase squirrel-cage motor.
Connect a brake resistor (FR-ABR, MRS type, MYS type) across terminals P/+ and PR.
(The brake resistor can not be connected to the 0.1K and 0.2K.)
Connect the brake unit (FR-BU2), power regeneration common converter (FR-CV)
or high power factor converter (FR-HC).
Remove the jumper across terminals P/+ and P1 and connect a DC reactor.
Single-phase 100V power input model is not compatible with DC reactor.
For earthing (grounding) the inverter chassis. Must be earthed (grounded).
