45 Amp, 3 Pole 440V 3-Phase............................. 25 Amp, 3 Pole Connection Type Because of the high amperage draw from this machine, we recommend that you hardwire it directly to your circuit breaker and install a locking shut-off lever (Figure 1) near the machine as a way to quickly disconnect the power. Figure 1. Locking shut-off lever. Circuit Capacity Always check to see if the wires in your circuit are capable of handling the amperage draw from your machine, as well as any other machines that could be operating on the same circuit. If you are unsure, consult a qualified electrician. If the circuit breaker trips or the fuse blows regularly, your machine may be operating on a circuit that is close to its amperage draw capacity. However, if an unusual amperage draw does not exist and a power failure still occurs, contact a qualified electrician. -6-G0524 Rip Saw Grounding Electrocutionorafire can result if the bandsaw isnotgroundedcor- rectly.Makesureall electricalcircuitsare grounded. DO NOT use the machine if it is not grounded. In the event of an electrical short, grounding provides electric current a path of least resistance to reduce the risk of electrical shock to the operator. Ground the power cord and this machine in accordance with all local codes and ordinances. Operating this machine when it is not properly grounded can result in electric shock or electrocution. Rewire To 440V (3-Phase) The Model G0524 can be rewired for 440V 3phase operation. This rewiring job consists of disconnecting the rip saw from the power source, changing the connections on the voltage transformer, changing the overload relays for the motors, and rewiring the motors. The necessary overload relays for this procedure can be purchased in the Model G0524 440V Conversion Kit (P/N P0524067) by calling our customer service number at (800) 523-4777. This procedure takes moderate electrical skill and the rewiring job must be inspected by a licensed electrician before the saw is connected to the power source. To rewire the Model G0524 to 440V 3-Phase: 1. Disconnect the rip saw from the power source! 2. Open the electrical box. 3. Remove the wire labeled “R” at the 220V terminal of the power transformer and connect it to the 440V terminal (Figure 2). 440V Terminal 220V Terminal Figure 2. The “R” wire is connected to the 440V terminal post to operate the rip saw on a 440V 3-phase power source. G0524 Rip Saw -7 4. Remove the RH10E/7C overload relay (Figure 3) and replace it with an RH10E/4C (3-5A) type, with the dial set to 4A. 5. Remove the RH18/20 overload relay (Figure 3) and replace it with an RH18/15 (12-18A) type, with the dial set to 12A. RH10E/7C RH18/20 Figure 3. Overload relays. 6. Wire the main motor and the feed motor as shown on the diagrams on the inside of each motor wire cover. After connecting wires together with the screws, nuts, and washers provided in the 440V conversion kit, completely wrap the connecting hardware in electrical tape so no metal is exposed where the wires connect. Note—Figures 4a and 4b have been provided for your reference and were current at the time that this manual was written. However, always use the diagram on the wire cover that comes with your motor!
