440V Operation
The Model G9968 Shaper is furnished with a 7
H.P. three-phase motor that can be wired to
440V. Under normal use, the motor draws
approximately 10 amps at 440V. We recommend
using a 10 amp circuit. This includes the appro-
priate wiring and circuit breaker. If frequent circuit
failures occur when using the shaper, contact our
service department.
The shaper must be connected to its own dedi-
cated 10A circuit. It should not share a circuit with
any other machine. A standard 3-pole breaker is
necessary for 440V use.
We recommend using a NEMA-style L20-30 plug
and outlet similar to that in Figure 2. You may
also "hard-wire" the shaper directly to your panel,
provided you place a disconnect near the
machine. Check the electrical codes in your area
for specifics on wiring requirements.

Grounding
In the event of an electrical short, grounding
reduces the risk of electric shock by providing a
path of least resistance to disperse electric cur-
rent.

This tool is equipped with an electric cord that has
an equipment-grounding conductor which must
be properly connected to a grounding plug. The
plug must be plugged into a matching outlet that
is properly installed and grounded in accordance
1
⁄
2
with all local codes and ordinances.
Improper connections of the electrical-grounding
conductor can result in the risk of electric shock.
The conductor with green or green and yellow
striped insulation is the electrical-grounding con-
ductor. If repair or replacement of the electric
cord or plug is necessary, do not connect the
equipment grounding conductor to a live terminal.
Extension Cords
We do not recommend the use of extension
cords on 220V or 440V equipment. It is much bet-
ter to arrange the placement of your equipment
and the installed wiring to eliminate the need for
extension cords. Should it be necessary to use
an extension make sure the cord is rated Hard
Service (grade S) or better. Refer to the chart in
Section 1: Safety to determine the minimum
gauge for the extension cord. The extension cord
must also contain a ground wire and plug pin.
Always repair or replace extension cords when
they become worn or damaged.
This equipment must be
grounded. Verify that any
existing electrical outlet
and circuit you intend to
plug
into
is
actually
grounded. Under no cir-
cumstances should the
grounding pin from any
three-pronged
plug
removed. Serious injury
may occur.
