Model G0449/G0450 (Mfd. Since 8/13)
Circuit Requirements for 480V
This machine can be converted to operate on a
480V power supply (refer to Voltage Conversion
instructions) that has a verified ground and meets
the following requirements:
Acceptable Voltage Range ............ 432V–528V
Cycle ..........................................................60 Hz
Phase .................................................... 3-Phase
Power Supply Circuit ......................... 30 Amps
Connection Type ..............................Hardwired
Extension Cords
Since this machine must be permanently con-
nected to the power supply, an extension cord
cannot be used.

Conduit Conduit
A permanently connected (hardwired) power sup-
ply is typically installed with wires running through
mounted and secured conduit. A disconnecting
means, such as a locking switch (see following
figure), 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.
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.
Grounding Instructions
In the event of a malfunction or breakdown,
grounding provides a path of least resistance
for electrical current to reduce the risk of electric
shock. A permanently connected machine must
be connected to a grounded metal permanent wir-
ing system; or to a system having an equipment-
grounding conductor. All grounds must be verified
and rated for the electrical requirements of the
machine. Improper grounding can increase the
risk of electric shock!
Phase Converter Precaution
The power from the manufactured leg may dam-
age electrical components if connected to the
wrong incoming power terminal on your machine.
Only connect the manufactured leg to the L2 ter-
minal on the incoming power terminal block (see
Page 19 for instructions). DO NOT use a static
phase converter, as they notoriously damage
electrical components.
