INSTALLATION AND WIRING
Connect these terminals to the commercial power supply.
Do not connect anything to these terminals when using the high power factor
converter (FR-HC2), multifunction regeneration converter (FR-XC)
regeneration common converter (FR-CV).
Connect these terminals to a three-phase squirrel cage motor or a PM motor.
Connect the brake unit (FR-BU2, FR-BU, BU), power regeneration common
converter (FR-CV), power regeneration converter (MT-RC), high power factor
converter (FR-HC2), multifunction regeneration converter (FR-XC), or DC power
supply (under DC feeding mode).
Do not remove the jumper across terminals P/+ and P1 except for connecting the
power regeneration common converter (FR-CV), the high power factor converter
(FR-HC2), or multifunction regeneration converter (FR-XC)
For earthing (grounding) the inverter chassis. This must be earthed (grounded).
