SECTION 2: POWER SUPPLY

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, or

equipment damage may

occur if machine is not

correctly grounded and

connected to the 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.)
