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 a qualified
electrician in accordance with all applicable
codes and 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
Model SB1016 Full-Load Rating 220V ...... 30A
Model SB1036 Full-Load Rating 440V ...... 15A
For your own safety and protection of property,
consult a qualified electrician if you are unsure
about wiring practices or electrical codes in
your area.
Note: The circuit requirements listed in this
manual apply to 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 that the circuit is properly sized for safe
operation.
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.
Circuit Information
Circuit Requirements for 440V
(Model SB1036)
Nominal Voltage ............................... 440V/480V
Cycle .............................................................60 Hz
Phase .............................................. Three-Phase
Circuit Rating....................................... 20 Amps
Connection Type ..............Hardwire (Page 24)
This machine is prewired to operate on a 440V
power supply circuit that has a verified ground
and meets the following requirements:
This machine is equipped with a frequency
drive that contains sensitive electronics,
which can be damaged by a phase converter.
DO NOT use a phase converter to power this
machine. Doing so will void the warranty.
