Re-Wiring the Saw for 208-240V Power
Before you
re-wire the motor for 208-240V power you must first install a 230V contactor box assembly
(CNS-WA-014). The contactor box assembly that comes with your saw is only rated for 110-120V power and it
is not compatible with the motor in the 208-240V configuration. To use 208-240V power, you must purchase a
SawStop 230V contactor box assembly and follow the installation instructions that are provided with it.
.
Only after the 230V contactor box assembly has been installed on your saw should you begin re-wiring the
motor. The motor that came with your saw is pre-wired for 110-120V power. The following procedure describes
how to re-wire the motor for 208-240V power.
•
There are two cords that extend out from the back of the saw cabinet: a long cord with a 110-120V male
plug to connect to a power outlet, and a short cord with a female plug to connect to the motor. Unplug both
cords so the saw is disconnected from power and from the motor.
•
Remove the motor belt by opening the belt guard and lifting the motor upward to release tension in the
belt.
•
Remove the motor from the saw by loosening the two lock down set screws that hold the motor in place
(use the included 3 mm hex key), and then slide the mounting pins out of the corresponding holes in the
rear trunnion (see Fig. 17 on page 23).
•
Locate the junction box underneath the motor (see Fig. 38 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. 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.
•
Locate the additional wire nut that is included with the 230V contactor box assembly. Use the three wire
nuts to connect the wires and then wrap each wire nut 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.
•
Reinstall the motor and motor belt as described on pages 23 and 24.
•
Plug the male end of the motor cord into the female plug on the matching short cord that extends out from
the back of the saw cabinet.
•
The 230V contactor box assembly comes with a NEMA 6-15P plug attached to the end of the main power
cable. If you need to replace this plug or replace the power cord with a longer one, follow the instructions
on page 38.
•
Your saw is now ready to use with 208-240V power.
