Procedure

  1. Push down on the hooks at Position A and Position B and pull it away from the VFD68 drive, using the hooks at Position C as supporting points (Figure 1).
    Figure 1. Release the Hooks and Remove the Front Cover

  2. Remove the high-voltage wiring cover at the bottom of the VFD68 drive by pulling in the direction of Arrow A (Figure 2).

    Important: Use UL Listed copper, stranded wire with insulation rated at 75°C (167°F) for wiring in Step 3 and Step 4. See .
  3. Connect a 575 VAC three-phase power supply to Terminals R/L1, S/L2, and T/L3 (Figure 3).

    For supplied three-phase power, connect the high-voltage power supply to terminals R/L1, S/L2, and T/L3 on the drive (Figure 3).

    For supplied single-phase power, connect the high-voltage power supply to terminals L1 and L3 (Figure 3).

  4. Connect the motor wiring to high-voltage output terminals U, V, and W on the drive (Figure 3).

  5. Connect earth ground wiring to the earth ground terminals on the VFD68 drive and on the motor.
  6. Replace the high-voltage wiring cover.
    Note: When replacing the high-voltage cover, carefully space and position the leads through the vents or wire slots.
