Power supply
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 alarm display and alarm 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.
Do not turn off the power supply for control circuit (R1/L11, S1/L21) with
the main circuit power (R/L1, S/L2, T/L3) on. Doing so may damage the
inverter. The circuit should be configured so that the main circuit power
(R/L1, S/L2, T/L3) is also turned off when the power supply for control
circuit (R1/L11, S1/L21) is off.
00380 or less : 60VA, 00470 to 02160 : 80VA
Connect the brake unit (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. (For the 01800 or more, a DC reactor
is standard-equipped.)
For earthing the inverter chassis. Must be earthed.
