Grounding Instructions - Delta 22-540 Instruction Manual

CONNECTING TOOL TO POWER SOURCE
A separate electrical circuit should be used for your tools. This circuit should not be less than #12 wire and should be
protected with a 20 Amp time lag fuse. If an extension cord is used, use only 3-wire extension cords which have 3-
prong grounding type plugs and 3-hole receptacles which accept the tool's plug. Before connecting the motor to the
power line, make sure the switch is in the "OFF" position and be sure that the electric current is of the same
characteristics as indicated on the tool. All line connections should make good contact. Running on low voltage will
damage the motor.
Your tool is wired for 120 volt, 60 HZ alternating current. Before connecting the tool to the power source, make sure
the switch is in the "OFF" position. The no-load speed of the motor is 8000 RPM.
WARNING: THIS TOOL MUST BE GROUNDED WHILE IN USE TO PROTECT THE OPERATOR FROM
ELECTRIC SHOCK.
1 . A l l g r o u n d e d , c o r d - c o n n e c t e d t o o l s :
In the event of a malfunction or breakdown, grounding
provides a path of least resistance for electric current to
reduce the risk of electric shock. This tool is equipped
with an electric cord having an equipment-grounding
conductor and a grounding plug. The plug must be
plugged into a matching outlet that is properly installed
and grounded in accordance with all local codes and
ordinances.
Do not modify the plug provided - if it will not fit the outlet,
have the proper outlet installed by a qualified electrician.
Improper connection of the equipment-grounding
conductor can result in risk of electric shock. The
conductor with insulation having an outer surface that is
green with or without yellow stripes is the equipment-
grounding conductor. If repair or replacement of the
electric cord or plug is necessary, do not connect the
equipment-grounding conductor to a live terminal.
Check with a qualified electrician or service personnel if
t h e g ro u n d i n g i n s t r u c t i o n s a re n o t c o m p l e t e l y
understood, or if in doubt as to whether the tool is
properly grounded.
Use only 3-wire extension cords that have 3-prong
grounding type plugs and 3-hole receptacles that accept
the tool's plug, as shown in Fig. AA.
Repair or replace damaged or worn cord immediately.

2. Grounded, cord-connected tools intended for use on
a supply circuit having a nominal rating less than 150
volts:
This tool is intended for use on a circuit that has an outlet
that looks like the one illustrated in Fig. AA. The tool has
a grounding plug that looks like the plug illustrated in Fig.
AA. A temporary adapter, which looks like the adapter
illustrated in Fig. BB, may be used to connect this plug a
2-hole receptacle as shown in Fig. BB 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. The green-colored
rigid ear, lug, and the like, extending from the adapter
must be connected to a permanent ground such as a
properly grounded outlet box. Whenever the adapter is
used, it must be held in place with a metal screw.
NOTE: In Canada, the use of a temporary adapter is
not permitted by the Canadian Electric Code.
