ELECTRICAL REQUIREMENTS

220V/440V Operation

The

SHOP FOX

Model W1737 has a 10 HP, 220V

single-phase sanding motor, a 1 HP, 220V feed motor,

and a

⁄

HP table lift motor; the Model W1738 has 15

HP, 220V/440V three-phase sanding motor, a 1 HP,

220V/440V feed motor, and a

⁄

HP table lift motor.

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 ha

ndle

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

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.
