-
Loosen the screws on the front cover and remove the cover to access the
low-voltage wiring (Figure 1).
Figure 1. Loosen the Cover Screws and Remove the Front Cover
-
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. -
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).
-
Connect the motor wiring to high-voltage output terminals U, V, and W on the
drive (Figure 3).
Figure 3. High-Voltage Terminal Block Wiring
- Connect earth ground wiring to the earth ground terminals on the VFD68 Drive and on the motor.
-
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.
