440V Connection
5. Wire the sanding belt, conveyor belt, and
table elevation motors as shown in the dia-
grams on
Page 55
of the owner's manual.
This machine is prewired for 220V 3-phase power
but has the capability of operating on 440V power
with a minor conversion. The conversion consists
of replacing two overload relays and rewiring each
of the three motors.
Contact the Grizzly Order Desk at (800) 523-4777
to purchase the correct 440V conversion kit for
your model that includes the necessary two over-
load relays:

All wiring changes must be inspected by service
personnel or a qualified electrician before the
machine is connected to the power source. If, at
any time during this procedure you need help, call
Grizzly Tech Support at (570) 546-9663.
Note: When using a phase converter, the power
from the manufactured power leg (sometimes
called the wild wire) can fluctuate. Connect the
manufactured power leg to the S terminal to pre-
vent damage to the transformer. The wire from the
S terminal can handle some fluctuation because
it goes directly to the motor. The power going to
the R and T terminals goes to the transformer and
must be consistent to prevent damage.
To wire the sander to 440V:
1. DISCONNECT MACHINE FROM POWER!
2. Open the electrical box located on the back of
the machine.
3. On the transformer, remove the wire con-
nected to the 220V terminal and connect it to
the 440V terminal, as shown in
Figures 7.
4. Swap out the applicable overload relay at
the locations shown in
Figure 8, and set the
amperage dial to values listed in
Figure 8
.
