Terminal function description
Connect these terminals to the commercial power supply.
Connect these terminals to a three-phase squirrel cage motor or a PM
motor.
Connect an optional brake resistor (FR-ABR, MRS, or MYS model)
across terminals P/+ and PR. (A brake resistor cannot be connected to
the FR-E820-0008(0.1K), FR-E820-0015(0.2K), FR-E820S-
0008(0.1K), and FR-E820S-0015(0.2K).)
Connect the brake unit (FR-BU2, FR-BU, or BU), power regeneration
common converter (FR-CV), or multifunction regeneration converter
(FR-XC in power regeneration mode) to these terminals.
Remove the jumper across terminals P/+ and P1, and connect a DC
reactor.
When a DC reactor is not connected, the jumper across terminals P/+
and P1 should not be removed.
For earthing (grounding) the inverter chassis. Be sure to earth (ground)
the inverter.
