440V Conversion (W1738)

To connect this machine to 440V three-phase, you must purchase one LR3D-076 overload relay (Shop Fox PN: X1738003-1) and one LR3D-3322 overload relay (Shop Fox PN: X1738011-1).

To wire the W1738 to 440V, do these steps:

1.Disconnect the sander from the power source!

2.Open the electrical box located on the back of the machine.

3.Remove the wire labeled “1” at the 220V terminal of the control power transformer (Figure 6) and connect it to the 440V terminal (Figure 7).

4.Remove the LR3D-3355 overload relay (Figure 6), and replace it with an LR3D-3322 (X1738003-1) type, with the dial set to 18A.

5.Remove the LR3D-086 overload relay (Figure 6), and replace it with an LR3D-076 (X1738011-1) type, with the dial set to 1.7A.

6.Wire the sanding motor, conveyor motor, and table elevation motor as shown on the diagrams on the inside of each motor wire cover.

Note: The circled references on the diagrams repre- sent labels on the wires. Also, Figure 8 has been pro- vided for your reference and is current at the time of writing. However, always use the diagram on the wire cover that comes with your motor!
