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 or dedicated
IPM 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 and R1/L11, and S/L2
and 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.
15K or lower
200V class
400V class
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 55K or lower, remove the jumper across terminals
P/+ and P1, and connect the DC reactor. (Be sure to
connect the DC reactor supplied with the 75K or higher.)
When a DC reactor is not connected, the jumper across
terminals P/+ and P1 should not be removed.
For earthing (grounding) the inverter chassis. Must be
