36 SawStop 10” Professional Cabinet Saw
Re-Wiring a PCS175 Saw for 208-240V Power
The 1.75 hp Professional Cabinet Saw (PCS175) is confi gured from the factory to operate on 110-120V power.
However, you can convert the PCS175 to operate on 208-240V power by replacing the contactor assembly and
rewiring the motor. If you want to convert your PCS175 saw to run on 208-240V power, follow the procedure
below.
1. Replace the contactor assembly: The contactor assembly on the PCS175 is compatible with 110-120V power
only. If you want to operate the saw on 208-240V power, you must purchase a 230V contactor assembly from
SawStop (p/n PCS-WA-025). When you receive the new contactor assembly, follow the included instructions
carefully to install it on your saw. Be sure to unplug your saw before proceeding.
2. Rewire the motor: The motor included on the PCS175 is a dual voltage motor. It is wired from the factory to
run on 110-120V power. To convert the motor to run on 208-240V power, follow the steps below exactly:
• Extending from the 230V contactor box there is a 9 ft power cord with a NEMA 6-15P plug to connect to a
matching power outlet. Make sure the power cord is unplugged from the outlet so the saw is disconnected
from power. If you need to replace the plug with a different style 208-220V plug or if you need to replace
the power cord with a longer cord, see page 38
.
• Open the motor cover, locate the junction box underneath the motor (see Fig. 47 on page 35 ) and remove
the cover by loosening the Phillips-head screw.
• Inside the junction box are wires connected by two wire nuts. One wire nut connects two black wires and
one white wire. The other wire nut connects red, yellow and white wires. Remove any electrical tape from
the two wire nuts and then remove the two wire nuts.
• Re-wire the leads as shown in the 208-240V wiring diagram on page 37. Locate the additional wire nut
that is included with the 230V contactor box assembly. Connect the black wire coming from the power
cord to the white wire coming from the motor. Connect the white wire coming from the power cord to the
red wire coming from the motor. Finally, connect the black wire coming from the motor to the yellow wire
coming from the motor.
• Wrap each of the three wire nuts with two layers of new electrical tape.
• Double check the wiring to make sure it matches exactly the 208-240V schematic on page 37, and then
re-attach the junction box cover.
• Your saw is now ready to use with 208-240V power.
