3.3 Main Circuit Connection DiagramRefer to Figure 3.2 through Figure 3.8 when wiring the main circuit of the drive. Connections may vary based on drivecapacity. The DC power supply for the main circuit also provides power to the control circuit.u Three-Phase 200 V Class (2A0011 to 2A0273)Three-Phase 400 V Class (4A0005 to 4A0302)DriveMotor+MR/L1S/L2T/L3U/T1V/T2W/T3-M3-Phase power supply200 to 240 Vac, 50 to 60 Hz380 to 480 Vac, 50 to 60 Hz12-Pulse/18-PulseRectification (Option) <1><1> +M and -M are for rectification options only.
