Note: If you do not have three-phase power available to
supply the Model W1738, you will have to install a phase
converter at the power supply.
Witheithermachine,youmusthard-wireitto your
power panel and install an electrical box with a locking
shut-offlever.Keep in mind that a circuit being used
by other machines or tools at the same time will add to
thetotalloadbeingapplied.Adduptheloadratings of
all machines on the circuit. If this number exceeds the
rating of the circuit breaker or wiring, use a different
circuit.
—For the Model W1737220Vsingle-phaseoperation,
use a 50 amp circuit that has wiring rated to handle
this amperage draw.
—For the Model W1738220Vthree-phaseoperation,
use a 40 amp circuit that has wiring rated to handle
this amperage draw.
—For the Model W1738 440V three-phaseoperation,
use a 20 amp circuit that has wiring rated to handle
this amperage draw.

Phase Converter

Connection

If you do nothave three-phase power availableto the
W1738 sander, you will have to install a phase converter.
When using a phase converter, the power from the manu-
factured power leg (sometimes called the wild wire) can
fluctuate. Connect the manufactured power leg to the T
terminal to prevent damage to the transformer. The wire
from the T terminal can handle some fluctuation because
it goes directly to the motor. The power going to the R and
S terminals goes to the transformer and must not fluctuate
to prevent damage.
TURN OFF and LOCK your
master power switch so
no power is available
to the sander before
connecting electrical
wires! If you ignore
this warning serious
electrical shock may
occur causing injury or
death!
OFF
DO NOT attempt to work on your shop
electrical system if you are unsure
about electrical codes and wiring!
Seek assistance from a qualified elec-
trician. Ignoring this warning can cause
electrocution!
This machine must be
grounded! If you have
any questions about
correct electrical
installation, contact a
qualified electrician for
assistance to make sure
all connections are safe
and adhere to your local
electrical codes.
