Power Connections; Motor Specifications; Grounding Instructions - Delta 23-725 Instruction Manual

POWER CONNECTIONS

A separate electrical circuit should be used for your machines. 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 matching receptacle which will accept the machine's plug. Before connecting the machine to the
power line, make sure the switch (s) is in the "OFF" position and be sure that the electric current is of the same characteristics
as indicated on the machine. All line connections should make good contact. Running on low voltage will damage the
machine.
DO NOT EXPOSE THE MACHINE TO RAIN OR OPERATE THE MACHINE IN DAMP LOCATIONS.

MOTOR SPECIFICATIONS

Your machine is wired for 120 volts, 60 HZ alternating current. Before connecting the machine to the power source,
make sure the switch is in the "OFF" position.

GROUNDING INSTRUCTIONS

THIS MACHINE MUST BE GROUNDED WHILE IN USE TO PROTECT THE OPERATOR FROM
ELECTRIC SHOCK.
1. All grounded, cord-connected machines:
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 machine 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 conduc-
tor 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 the
grounding instructions are not completely understood, or if
in doubt as to whether the machine is properly grounded.
Use only 3-wire extension cords that have 3-prong grounding
type plugs and matching 3-conductor receptacles that
accept the machine's plug, as shown in Fig. A.
Repair or replace damaged or worn cord immediately.

2. Grounded, cord-connected machines intended for
use on a supply circuit having a nominal rating less
than 150 volts:
If the machine is intended for use on a circuit that has an
outlet that looks like the one illustrated in Fig. A, the machine
will have a grounding plug that looks like the plug illustrated
in Fig. A. A temporary adapter, which looks like the adapter
illustrated in Fig. B, may be used to connect this plug to a
matching 2-conductor receptacle as shown in Fig. B 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.
IN ALL CASES, MAKE CERTAIN THAT THE
R E C E P T A C L E I N Q U E S T I O N I S
PROPERLY GROUNDED. IF YOU ARE NOT
SURE, HAVE A QUALIFIED ELECTRICIAN
CHECK THE RECEPTACLE.
