  2. Remove the high-voltage wiring cover at the bottom of the VFD68 drive (Figure 2).
    Figure 2. Remove the High-Voltage Wiring Cover

    Important: Use UL Listed copper, stranded wire with insulation rated at 75°C (167°F) for wiring in Step 3 and Step 4. See High-Voltage Wire Size and Maximum Wire Length.
  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.
