Wire the Inverter Output to Motor
Step 7: The process of motor selection is beyond the scope of this manual. However, it

must be an AC induction motor with three phases. It should also come with a chassis
ground lug. If the motor does not have three power input leads, stop the installation
and verify the motor type. Other guidelines for wiring the motor include:
 Use an inverter-grade motor for maximum motor life (1600V insulation).
 For standard motors, use the AC reactor accessory if the wiring between the
inverter and motor exceeds 10 meters in length.
Simply connect the motor to the terminals [U/T1], [V/T2], and [W/T3] as shown in
page 2-17 to 2-19. This is a good time to connect the chassis ground lug on the drive as
well. The motor chassis ground must also connect to the same point. Use a star ground
(single-point) arrangement, and never daisy-chain the grounds (point-to-point).
 Check the mechanical integrity of each wire crimp and terminal connection.
 Replace the housing partition that covers access to the power connections.
CAUTION: Power terminal assignment is different compared to old models such as L100, L200
series, etc,. Pay attention when wiring the power cable
Logic Control Wiring
After completing the initial installation and powerup test in this chapter, you may need to
wire the logic signal connector for your application. For new inverter users/applications,
we highly recommend that you first complete the powerup test in this chapter without
adding any logic control wiring. Then you will be ready to set the required parameters for
logic control as covered in Chapter 4, Operations and Monitoring.
IMPORTANT!: Please be sure to set the motor nameplate data into the appropriate parameters
to ensure proper operation and protection of the motor:
* B012 is the motor overload protection value
* A082 is the motor voltage selection
* H003 is the motor kW capacity
* H004 is the number of motor poles
Please refer to the appropriate pages in this guide and the Instruction Manual for further
details.
