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 5,
depending on the model and voltage being used.
NOTICE
Extension Cords (220V Only)
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:
• Use at least a 12 gauge cord that does
not exceed 50 feet in length.
• Ensure that the extension cord contains
a ground wire and plug pin.
