Delta 14-651 Type III Manuel D'utilisation page 5

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. Im-
proper connection of the equipment-grounding conductor can result in risk of electric shock. The conductor with insula-
tion 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 ac-
cept 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:
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 receptacle in question is properly grounded. If you are not sure, have a
qualified electrician check the receptacle.

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 matching receptacle which will accept the machine's
plug. When using an extension cord, be sure
one heavy enough to carry the current of the machine.
An undersized cord will cause a drop in line voltage,
resulting in loss of power and overheating. Fig. C 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.
