Model G0853 (Mfd. Since 07/18)
-19-
Connection Type
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.
Extension Cords
Since this machine must be permanently con-
nected to the power supply, an extension cord
cannot be used.
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.
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!

The Model G0853 can be converted for 440V
operation. This conversion consists of: 1)
Disconnecting the saw from power, 2) moving the
transformer T1 wire from the 220V to 440V termi-
nal, 3) replacing the overload relays, 4) replacing
the power supply, and 5) rewiring the main and
scoring blade motors for 440V operation. See the
wiring diagrams inside the motor junction boxes for
detailed 440V wiring diagrams.
All wiring changes must be inspected by a quali-
fied electrician or service personnel before the
saw is connected to the power source. If, at any
time during this procedure you need help, call
Grizzly Tech Support at (570) 546-9663.
Contact the Grizzly Order Desk at (800) 523-4777

Phase Converters
Avoid using a static phase converter to supply
3-phase power for this machine, as it could
damage or decrease the life of sensitive electrical
components. If you must use a phase converter,
only use a rotary phase converter that is sized
at least 50% larger than the largest HP rating
of this machine. If using a phase converter to
supply power, only connect the manufactured leg
or "wild wire" to the "S" terminal. The S terminal
can handle power fluctuations because it is wired
directly to the motor.
