Power supply
Connect to the commercial power supply.
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 cannot be connected to the 0.1K or 0.2K.)
Connect the brake unit (FR-BU2).
Remove the jumper across terminals P/+ and P1 and connect a DC reactor.
For earthing (grounding) the inverter chassis. Must be earthed (grounded).
