Grizzly G0623X3 - Manual (Page 17)

Model G0623X/G0623X3 (Mfg. Since 5/12)
-15-
the model g0623X3 is prewired for 220v 3-
phase operation, but it can be rewired for 440v
operation.
to complete this conversion procedure, you must
buy a 440v magnetic switch and rewire the motor
for 440v operation. the 440v magnetic switch,
part p0623X30346a, can be purchased from
grizzly by calling 1-800-523-4777.
this rewiring job must be inspected by a quali-
fied electrician before the saw is connected to the
power source. also, the junction box on the motor
can be accessed easier for rewiring if the blade is
moved to 0˚ (90˚ to table) before beginning.

voltage conversion
to rewire the machine for 440v operation:
1. disCoNNeCt saW from poWer!
2. remove the cover of the magnetic switch.
3. disconnect all the wires from the incoming
power cords.
4. remove the magnetic switch and install the
new magnetic switch in the same manner
as the old switch was installed. refer to the
wiring diagram on
page 75 if you need help
remembering where the wires are attached.
5. remove the cabinet cover from the back of
the machine.
6. rewire the motor to 440v as shown in the
diagram on page 75.
7. replace the junction box cover, cabinet door
cover, and magnetic switch cover.

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!
extension cords
We do not recommend using an extension cord
with this machine. If you must use an extension
cord, only use it if absolutely necessary and only
on a temporary basis.
Extension cords cause voltage drop, which may
damage electrical components and shorten motor
life. Voltage drop increases as the extension cord
size gets longer and the gauge size gets smaller
(higher gauge numbers indicate smaller sizes).
Any extension cord used with this machine must
contain a ground wire, match the required plug
and receptacle, and meet the following require-
ments:
g0623X ............ 3 Wire, 10 aWg, 50 ft. or less
g0623X3 (220v) 4 Wire, 10 aWg, 50 ft. or less
g0623X3 (440v) ......................cannot be used
