Three-phase, 200 VAC to 240 VAC, -15% to +10%,
50Hz or 60Hz

Control power supply
terminals
Single-phase, 200 VAC to 240 VAC, -15% to +10%,
50Hz or 60Hz
B1, B2, B3
Regenerative Resistor
terminal
There is a short wiring between B2 and B3 at the factory.
When the busbar capacitance is insufficient, remove the
short wiring, and connect an external regenerative
resistor between B1 and B2.
P1, P2, N
DC terminals
There is a short wiring between P1 and P2 at the factory.

For using a DC reactor, remove the short wiring, and
connect a DC reactor between P1 and P2.

For using a DC power supply, connects P2 to the
positive pole, and connects N to negative pole.

For the common DC bus, connect all P2 of Drive to
the positive pole, and N to the negative pole.
Ground terminal
Always connect this terminal to prevent electric shock.
