Grizzly G9962Z, G0582, 9962ZX, G0445 instruction manual 440V Connection

440V Connection

To connect this machine to 440V three-phase, you must purchase two overload relays. Each machine model may require unique relays, so refer to 440V Conversion Relays on Page 65 for the relay part numbers.

If you do not have three-phase power available for your wide belt sander, you must install a phase converter such as a Grizzly Phase Converter.

Note: When using a phase converter, the power from the manufactured power leg (sometimes called the wild wire) can fluctuate. Connect the manufactured power leg to the S terminal to pre- vent 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 sander to 440V:

1.DISCONNECT THE SANDER FROM THE POWER SOURCE!

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

3.On the transformer, remove the wire labeled "1" connected to the 220V terminal for your model of sander, and connect it to the 440V terminal as shown in Figure 7.
