440V Connection
(G0446/G0539)
To connect this machine to 440V
If you do not have
When using a phase converter, the power from the manufactured power leg (sometimes called the wild wire) can fluctuate. Connect the manu- factured power leg to the S terminal to prevent damage to the transformer. The wire from the S terminal can handle some fluctuation because it goes directly to the motor. The power going to the R and T terminals goes to the transformer and must be consistent to prevent damage.
To wire the Model G0446/G0539 to 440V:
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 7) and connect it to the 440V termi- nal.

5.Remove the LR3D086 overload relay (Figure 8), and replace it with an LR3D076 (1.6-2.5A) type, with the dial set to 1.7A.
6.Wire the sanding belt, conveyor belt, and table elevation motors as shown on the diagrams on the inside of each motor wire cover.
Note: The circled references on the diagrams represent labels on the wires. Also, Figure 9 below has been provided 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!
