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. 19. 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. 20, 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
properly grounded outlet can be installed by a qualified
electrician. THIS ADAPTER IS NOT APPLICABLE IN
CANADA. The green-colored rigid ear, lug, etc.,
extending 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. 20.
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
voltage 120/240 volt motor. The dust collector motor is
shipped ready-to-run for 120 volt operation; however, it
may be converted 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 1-800-223-7278 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) replacing 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
connected to an outlet having the same configuration as
the plug illustrated in Fig. 21. No adapter is available or
should be used with the 240 volt plug.

AS A PRECAUTION IN ALL CASES, MAKE CERTAIN
THE RECEPTACLE IN QUESTION IS PROPERLY
GROUNDED. IF YOU ARE NOT SURE, HAVE A
CERTIFIED ELECTRICIAN CHECK THE RECEPTACLE.
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 tool. An undersized cord will cause a drop in line
voltage, resulting in loss of power and overheating. Fig. 22 & 23, shows the correct gauge to use depending on the
cord length. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.
