Converting from 230 Volt to 460 Volt (Three Phase Only)

To convert from 230 volt to 460 volt:

1.Remove the four Phillips head screws on the switch plate (Figure 8) and tilt the switch plate down. Then remove the cover of the switch box.

2.Replace the current contactor with the 460V magnetic contactor (part no. 2013-102D for model 2013; part no. 2415-102D for model 2415; purchased separately).

3.Re-connect the motor leads according to the diagrams inside the motor junction box. These diagrams are also found on pages 56 and 57 of this manual. (Diagram in motor junction box should take priority.)

4.Change the lamp input power from 230V to 460V in the panel of the transformer (Figure 9) in accordance with the diagrams on pages 56 and 57.

5.If using a plug, install a proper UL/CSA listed plug suitable for 460V operation.

IMPORTANT: Consult the diagrams on pages 56 and 57 for clarification of any of these changes on 230V to 460V conversion.

Three-Phase Test Run

On the three-phaseunit, after wiring has been completed, you should check that the wires have been connected properly:

1.Open lower front door of the Band Saw.

2.Connect machine to power source and press the start button, shown in Figure 28, for just an instant, then press the stop button. (See “Operating Controls” on page 21 for further information on the control buttons.)

3.The lower wheel should rotate clockwise as viewed from the front of the machine. If the rotation of the lower wheel is incorrect, disconnect machine from power.

4.Switch any two of the three wires at "R,S,T" (see “Electrical Connections”, pages 56 and 57) and re-connect machine to power source.
