220V Operation

The SHOP FOX® Model W1678 Drum Sander uses one 220 VAC single-phase motor. This sanding drum motor is rated at 5 HP and draws approximately 25 amps under a normal sanding load.The 13 HP varyable speed conveyor motor uses 60 VDC and draws approximately 2 amps.

Refer to the wiring diagram on Pages 35 and 36, and hard wire the power supply to the sander, or use a NEMA-style L6-30 plug and receptacle as shown in Figure 9. In either case, the supply circuit, circuit breaker, or fuse must be able to carry a load of at least 27 Amps. Remember other machines using this circuit add to the total electrical load applied to the circuit. If this total amperage load exceeds the amperage rating of the circuit breaker or fuse, use a different circuit with a higher amperage rating.

DO NOT modify an existing low-amperage circuit by only replacing the circuit breaker with a breaker rated for a higher amperage. The breaker and the complete circuit must be replaced by a qualified electrician.

Extension Cords

We do not recommend using an extension cord with 220V equipment because the cord can generate heat that may cause fire or circuit damage. If you must use an extension cord, use the guidelines listed below and TABLE 2 to determine the correct cord length and gauge. The amp rating of both motors combined is 27 amps at normal operation; however, the amperage will increase or decrease depending on the load you apply on the Double Drum Sander.

•Use a Standard Service (Grade S) cord or better

•Use a cord that is 50 feet or less only •Use a cord with a NEMA-style L6-30 plug •Use an undamaged cord only

Grounding

Any electrical outlet and

circuit that you plug your

machine into must be grounded. Serious injury or fire may occur if this warning is ignored!

Ground this machine! The electrical cord supplied with the Model W1678 does not come with a 220 volt plug. Use a plug with a ground pin as shown in Figure 9. If your receptacle does not accommodate a NEMA-styleL6-30 plug with a ground pin, have the receptacle replaced by a qualified electrician or have an appropriate adapter installed and grounded properly.

NOTICE

When using an adapter, always make sure it is grounded.

Remember, an adapter with a grounding wire does not guarantee the machine will be grounded. A ground source must always be verified in the electrical circuit within the wall or conduit.
