P R E P A R A T I O N

For your own safety and protection of property,

consult an electrician if you are unsure about

wiring practices or applicable electrical codes.

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 information

Circuit Requirements for 110V

This machine is prewired to operate on a 110V

power supply circuit that has a verified ground

and meets the following requirements:

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

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

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

Circuit Rating....................................... 20 Amps

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

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.

Circuit Requirements for 220V

Nominal Voltage ............................... 220V/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:

grounding Requirements

This machine must be grounded! In the event

of certain types of malfunctions or breakdowns,

grounding provides a path of least resistance

for electric current in order to reduce the risk of

electric shock.

5-15 RECEPTACLE

Figure 2. NEMA 5-15 plug and receptacle.

This machine is equipped with a power cord

that has an equipment-grounding wire and a

grounding plug (similar to the figure below).

The plug must only be inserted into a matching

receptacle (outlet) that is properly installed and

grounded in accordance with all local codes and

ordinances.

For 110V Connection (prewired)

For 220V Connection

Use the plug type listed in the Circuit

Requirements for this voltage. The listed plug

(similar to the figure below) has an equipment-

grounding wire to safely ground the machine.
