Power Supply 
Requirements

Electrocution or fire may 

occur if machine is not 

correctly grounded and 

attached to the power 

supply. Use a qualified 

electrician to ensure a safe 

power connection.

Before installing the machine, consider the 

availability and proximity of the required power 

supply circuit. If an existing circuit does not meet 

the requirements for this machine, a new circuit 

must be installed.

To minimize the risk of electrocution, fire, 

or equipment damage, installation work and 

electrical wiring must be done by an electrician 

or qualified service personnel in accordance with 

applicable electrical codes and safety standards.

Availability

The full-load current rating is the amperage 

a machine draws at 100% of the rated output 

power. On machines with multiple motors, this is 

the amperage drawn by the largest motor or sum 

of all motors and electrical devices that might 

operate at one time during normal operations.

The full-load current is not the maximum 

amount of amps that the machine will draw. If 

the machine is overloaded, it will draw additional 

amps beyond the full-load rating.

If the machine is overloaded for a sufficient 

length of time, damage, overheating, or fire may 

result—especially if connected to an undersized 

circuit. To reduce the risk of these hazards, 

avoid overloading the machine during operation 

and make sure it is connected to a power supply 

circuit that meets the requirements in the 

following section.

Full-Load Current Rating

Full-Load Rating at 110V ..................... 7 Amps

For your own safety and protection of property, 

consult an electrician if you are unsure about 

wiring practices or applicable electrical codes.

Note: The circuit requirements in this manual 

are for a dedicated circuit—where only one 

machine will be running at a time. If this 

machine will be connected to a shared circuit 

where multiple machines will be running at 

the same time, consult a qualified electrician to 

ensure the circuit is properly sized.

A power supply circuit includes all electrical 

equipment between the main breaker box or fuse 

panel in your building and the incoming power 

connections inside the machine. This circuit 

must be safely sized to handle the full-load 

current that may be drawn from the machine for 

an extended period of time. (If this machine is 

connected to a circuit protected by fuses, use a 

time delay fuse marked D.)

Circuit Requirements for 110V

This machine is prewired to operate on a power 

supply circuit that has a verified ground and 

meets the following requirements:

Nominal Voltage ..................... 110V/115V/120V

Cycle .............................................................60 Hz

Phase ..............................................Single-Phase

Circuit Rating....................................... 15 Amps

Plug/Receptacle (included) ...........NEMA 5-15

Full-Load Rating at 220V .................. 3.5 Amps

Circuit Information

Circuit Requirements for 220V

Nominal Voltage ........... 208V/220V/230V/240V

Cycle .............................................................60 Hz

Phase ..............................................Single-Phase

Circuit Rating....................................... 15 Amps

Plug/Receptacle ...............................NEMA 6-15

This machine can be converted to operate on 

a 220V power supply. To do this, follow the 

Voltage Conversion instructions included in 

this manual. The intended 220V circuit must 

have a verified ground and meet the following 

requirements:
