Connect the input power supply.
200-V class: 170 to 264 VAC, 50/60 Hz ±5%
400-V class: 323 to 528 VAC, 50/60 Hz ±5%
Connect a 3-phase motor.
The maximum output voltage depends on the input power supply
voltage.
200-V class: 170 to 264 VAC
400-V class: 323 to 528 VAC
Remove the short-circuit bar between the terminals +1 and P/+2,
and connect the optional power factor improvement DC reactor.
Connect optional external braking resistors. The terminal RB is
provided for the inverters with 22 kW or lower capacity.
Connect optional regenerative braking units.
The inverter's ground terminal. Connect this terminal to the
ground.
Class D (200-V class), Class C (400-V class)
Power supply terminals for inverter control circuit.
