Rewiring for Software Change Compatibility
Some minor wiring changes must be made for the machine to accept the program changes.
1. Lockout/tagout out as previously described on page 4, and locate the VFD in the
main electrical enclosure. It is shown on page 10.
2. Make the wiring changes according to Figure 7
. All supplies needed are included.
3. Gently tug on newly installed wires to ensure they are securely attached.
4. Reinstall the VFD cover.
Figure 7: Wire Connection Points
It is easiest to connect the wires by removing the terminal block,
connecting the wires, then putting the terminal block back in place.
TIP:
16
-gauge wires are larger in diameter than
18
-gauge wires.
