SECTION 2: CIRCUIT REQUIREMENTS

Serious personal injury could occur if you
connect the machine to power before com-
pleting the setup process. DO NOT connect
the machine to the power until instructed
later in this manual.
Electrocution or fire could
result if machine is not
grounded and installed in
compliance with electrical
codes. Compliance MUST
be verified by a qualified
electrician!
NOTICE
The Model G0643 is prewired for 220V,
single-phase. If you plan to operate the
machine at 110V, the motor must be rewired,
and the 110V version of the electrical box
and ON switch must be installed. Refer to
Rewiring to 110V on Page 9 for detailed
instructions.
Full Load Amperage Draw
Motor Draw at 110V ........................... 20.8 Amps
Motor Draw at 220V (prewired) ......... 10.4 Amps
Circuit Requirements
You MUST connect your machine to a grounded
circuit that is rated for the amperage given below.
Never replace a circuit breaker on an existing cir-
cuit with one of higher amperage without consult-
ing a qualified electrician to ensure compliance
with wiring codes. If you are unsure about the
wiring codes in your area or you plan to con-
nect your machine to a shared circuit, consult
a qualified electrician.
Minimum 110V Circuit ........................... 30 Amps
Minimum 220V Circuit (pre-wired) ......... 15 Amps

Power Connection Device
The power connection device depends on the
type of installed or planned service. We recom-
mend using one of the devices shown in Figure 2,
depending on the voltage being used.
Figure 2. Recommended plug types.
Extension Cords
Using extension cords may reduce the life of the
motor. Instead, place the machine near a power
source. If you must use an extension cord:
• For 110V, use at least a 10 gauge cord that
does not exceed 50 feet in length.
• For 220V, use at least a 14 gauge cord that
does not exceed 50 feet in length.
• The extension cord must have a ground wire
and plug pin.
