G0677 24" Planer/Sander
To connect the Model G0677 to 440V three-phase
power, you must purchase two thermal overload
relays, Parts PH29338134 and PH29338135,
or purchase the 440V Conversion Kit Part
P06778134. (refer to
Page 86). To purchase the
relays or the kit, call Grizzly Customer Service at
(800) 523-4777.
If you do not have three-phase power available
for your planer/sander, you must install a phase
converter. We recommend using a Grizzly Phase
Converter such as the Model H3741 (refer to
Accessories on Page 34). Refer to the Phase
Converter sub-section on Page 11 for require-
ments and setup.
All wiring changes must be performed by a quali-
fied electrician before the planer/sander is con-
nected to the power source. If, at any time during
this procedure you need help, call Grizzly Tech
Support at (570) 546-9663.
To rewire the Model G0677 for 440V opera-
tion:
1. DISCONNECT PLANER/SANDER FROM
POWER!
2. Open the main wiring box located on the back
of the machine (see
Figure 1, Page 3).
3. On the transformer, remove the #1 wire con-
nected to the 220V terminal and connect it to
the 440V terminal, as shown in
Figure 5
.

4. Swap out the sanding motor relay LR3D-
3355 and conveyor motor relay LR3D-086
with the 440V thermal relays at the locations
shown in
Figure 6, and set them to 18A and
1.7A respectively.
—Use 440V Conversion Kit #P06778134
or purchase Part PH29338134 and
PH29338135, and change out the two
relays.
