Delta 50-840 instruction manual Extension Cords, Single Phase Operation

120 VOLT,

SINGLE PHASE OPERATION

This tool must be grounded while in use to protect the operator from electric shock. The motor recommended for use with your dust collector is shipped wired for 120 Volt, Single Phase, and is equipped with an approved 3-conductor cord and 3-prong grounding type plug to fit the proper grounding type receptacle, as shown in Fig. 16. The green conductor in the cord is the grounding wire. Never connect the green wire to a live terminal.

A temporary adapter, shown in Fig. 17, is available for connecting 3-prong grounding type plugs to 2-prong receptacles if a properly grounded outlet is not available. The temporary adapter should be used only until a prop- erly grounded outlet can be installed by a qualified electrician. THIS ADAPTER IS N O T APPLICABLE IN CANADA. The green-colored rigid ear, lug, etc., extend- ing from the adapter, is the grounding means and must be connected to a permanent ground such as to a properly grounded outlet box, as shown in Fig. 17. Whenever the adapter is used, it must be held in place with a metal screw.

240 VOLT,

SINGLE PHASE OPERATION

The motor supplied with your dust collector is a dual volt- age 120/240 volt motor.The dust collector motor is shipped ready-to-run for 120 volt operation; however, it may be con- verted for 240 volt operation.

The conversion of your dust collector for 240 volt operation must be done by qualified electrical personnel. Should you desire to have your dust collector converted for 240 volts, take your dust collector to your local Authorized Delta Service Center. Call 1-800-438-2486 for the location of the nearest Authorized Service Center.The Service Center will be able to convert your dust collector for 240 volts by

(a)re-wiring the motor for 240 volts;(b)installing a 240 volt attachment plug to the power supply cord; and (c) replac- ing the single pole on/off switch shipped with your dust collector with a double pole switch.

The dust collector with a 240 volt plug should only be con- nected to an outlet having the same configuration as the plug illustrated in Fig. 18. No adapter is available or should be used with the 240 volt plug.

EXTENSION CORDS

Use proper extension cords. Make sure your extension cord is in good condition and is a 3-wire extension cord which has a 3-prong grounding type plug and a 3-hole receptacle which will accept the tool s plug. When using an extension cord, be sure to use one heavy enough to carry the current of the dust collector.An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. Fig. 19, shows the correct size to use depending on cord length and voltage. If in doubt, use the next heavier gage. The smaller the gage number,the heavier the cord.
