Converting from 230 Volt to 460 Volt (Three Phase Only)
Consult the wiring diagram inside the starter box cover. A similar diagram is also included at the back of this manual. The sander must comply with all local and national codes after being wired.
1.Replace the current contactor with the 460V magnetic contactor (part no.
2.
3.If using a plug, install a proper UL/CSA listed plug suitable for 460 volt operation.
Three-Phase Test Run
On the
1.Connect machine to power source and press the start button.
2.The sanding disc and belt should move in accordance with the arrow directions on the machine. If the movement is backward, stop the machine and disconnect machine from power.
3.Switch any two of the three wires at "R,S,T".
Grounding Instructions
(Refer to page 7 for more information on grounding this machine.) This machine must be grounded. In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock.
Improper connection of the equipment- grounding conductor can result in a risk of electric shock. The conductor with insulation having an outer surface that is green with or without yellow stripes, is the equipment- grounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the
Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded.
Repair or replace a damaged or worn cord immediately.
Extension Cords
An extension cord is not recommended; if possible, position your Sander within reach of the power supply. If an extension cord becomes necessary, make sure the cord rating is suitable for the amperage listed on the machine’s motor plate. An undersize cord will cause a drop in line voltage resulting in loss of power and overheating.
Use the chart in Figure 14 as a general guide in choosing the correct size cord. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.
