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
V olt, Single Phase, and is equipped with an approved
3-conductor cord and 3-prong grounding type plug to
fit the proper grounding type recept acle, 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
recept acles if a properly grounded outlet is not available.
The temporary adapter should be used only until a prop erly grounded outlet can be inst alled by a qualified
electrician. THIS ADAPTER IS NOT 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 met al 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 volt s,
take your dust collector to your local Authorized Delt a
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 volt s by
(a) re-wiring the motor for 240 volt s; (b) inst alling a 240 volt
att achment plug to the power supply cord; and (c) replac ing the single pole on/of f 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.
Fig. 19
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
recept acle 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 volt age resulting in loss of power
and overheating. Fig. 19, shows the correct size to use
depending on cord length and volt age. If in doubt, use
the next heavier gage. The smaller the gage number, the
heavier the cord.
