Connect to the commercial power supply.
Keep these terminals open when using the high power factor converter
(FR-HC, MT-HC) or power regeneration common converter (FR-CV).
Connect a three-phase squirrel-cage motor.
Connected to the AC power supply terminals R/L1 and S/L2. To retain the
fault display and fault output or when using the high power factor converter
(FR-HC, MT-HC) or power regeneration common converter (FR-CV),
remove the jumpers from terminals R/L1-R1/L11 and S/L2-S1/L21 and
apply external power to these terminals.
The power capacity necessary when separate power is supplied from R1/
L11 and S1/L21 differs according to the inverter capacity.
00380 or less : 60VA, 00470 or more : 80VA
Connect the brake unit (FR-BU2, FR-BU, BU and MT-BU5), power
regeneration common converter (FR-CV), high power factor converter (FR-
HC and MT-HC) or power regeneration converter (MT-RC).
For the 01160 or less, remove the jumper across terminals P/+ - P1 and
connect the DC reactor. (Be sure to connect the DC reactor supplied with
the 01800 or more.)
For earthing the inverter chassis. Must be earthed.
