Circuit Requirements for 440V
Nominal Voltage ............................... 440V/480V
Cycle .............................................................60 Hz
Phase ....................................................... 3-Phase
Circuit Rating....................................... 30 Amps
Connection ..... Hardwire with Locking Switch
This machine can be converted to operate on
a 440V power supply. To do this, follow the
Voltage Conversion instructions included in
this manual. The intended 440V circuit must
have a verified ground and meet the following
requirements:
Extension Cords
Since this machine must be permanently
connected to the power supply, an extension cord
cannot be used.
Phase Converters
DO NOT use a static phase converter to create
3-phase power—it can quickly decrease the life
of electrical components on this machine. If you
must use a phase converter, only use a rotary
phase converter.
Serious injury could occur if you connect
the machine to power before completing the
setup process. DO NOT connect to power until
instructed later in this manual.
Circuit Requirements for 220V
This machine is prewired to operate on a power
supply circuit that has a verified ground and
meets the following requirements:
Nominal Voltage ..................... 220V/230V/240V
Cycle .............................................................60 Hz
Phase ....................................................... 3-Phase
Circuit Rating....................................... 50 Amps
Connection ..... Hardwire with Locking Switch

Conduit
A permanently connected (hardwired) power
supply is typically installed with wires running
through mounted and secured conduit. A
disconnecting means, such as a locking switch
(see Figure 5), must be provided to allow the
machine to be disconnected (isolated) from the
power supply when required. This installation
must be performed by an electrician in
accordance with all applicable electrical codes
and ordinances.
