-14- G0445/G0582/G9962Z/9962ZX Wide Belt Sander
440V Connection
To wire the sander to 440V:
1. DISCONNECT THE SANDER FROM THE
POWER SOURCE!
2. Open the electrical box located on the back
of the machine.
3. On the transformer, remove the wire labeled
" 1 " connected to the 220V terminal for your
model of sander, and connect it to the 440V
terminal as shown in
Figure 7.
Figure 7. 440V transformer connection.
5. Wire the sanding belt, conveyor belt, and
table elevation motors as shown on the
diagrams on the inside of each motor wire
cover, or refer to
Motor Wiring on Page 44.
To connect this machine to 440V three-phase,
you must purchase two overload relays. Each
machine model may require unique relays, so
refer to
440V Conversion Relays on Page 65 for
the relay part numbers.
If you do not have three-phase power available for
your wide belt sander, you must install a phase
converter such as a Grizzly Phase Converter.
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.
4. Swap out the applicable thermal relay at the
locations shown in Figure 8, and set it to the
overload values listed.
