    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. Connect the high-voltage power supply to terminals R/L1, S/L2, and T/L3 on the drive (Figure 3).
    Note: If three-phase power is not available as supply power for the VFD68 Drive, refer to the VFD68 Variable Frequency Drive Technical Bulletin (Part No. 24-7664-3051).
  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.
