SECTION 2: POWER SUPPLY

Full-Load Current Rating at 120V 13.92 Amps

Availability

Before installing the machine, consider the avail-
ability 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 all 
applicable codes and standards.

Electrocution, fire, shock, 

or equipment damage 

may occur if machine is 

not properly grounded 

and connected to power 

supply.

Full-Load Current Rating

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  over-
loading  the  machine  during  operation  and  make 
sure it is connected to a power supply circuit that 
meets the specified circuit requirements.

For your own safety and protection of 

property, consult an electrician if you are 

unsure about wiring practices or electrical 

codes in your area.

Note: Circuit requirements in this manual apply to 
a dedicated circuit—where only one machine will 
be running on the circuit at a time. If machine will 
be connected to a shared circuit where multiple 
machines may be running at the same time, con-
sult an electrician or qualified service personnel to 
ensure circuit is properly sized for safe operation.

A  power  supply  circuit  includes  all  electrical 
equipment between the breaker box or fuse panel 
in the building and the machine. The power sup-
ply circuit used for this machine must be sized to 
safely handle the full-load current 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.)

120V Circuit Requirements

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

Power Supply Circuit ......................... 20 Amps

Serious injury could occur if you connect 

machine to power before completing setup 

process. DO NOT connect to power until 

instructed later in this manual.
