Electrical Power Connection - SawStop CNS175 Owner's Manual

Preparing Your Saw for Use

Electrical Power Connection

WARNING! Do not connect the saw to electrical power until the saw is
completely assembled and you have read and understood this entire manual.
The A-C motor that comes with your saw is rated at 1.75 hp and operates at 60 Hz. It can be used with
110-120V or 208-240V power. It comes from the factory pre-wired for 115V, which means it will work with
110-120V power. Instructions to re-wire the saw for 208-240V power can be found on page 36. If you plan on
re-wiring the saw for 208-240V power you must purchase a 230V contactor box assembly (CNS-WA-014),
because the contactor box assembly that comes with your saw is only rated for 110-120V power.
The motor draws 14 amps when it is wired for 110-120V power, and 7 amps when it is wired for 208-240V
power. Do not use any other motor to power your saw. Connect the saw to an electrical circuit that is protected
by a 20 amp breaker.
Note: The A-C motor that comes with contractor saw model CNS175-AU (sold in Australia) is pre-wired for
208-240V power and operates at 50 Hz. The contactor box assembly that comes with CNS175-AU is designed
for 240V / 50Hz power.
If you use an extension cord to supply power to your saw, use only extension cords that have three-prongs
(including one grounded prong). Also, the extension cord must be heavy enough to carry enough current for the
motor. An extension cord that is undersized or too long can cause a voltage drop that will decrease the power
supplied to the motor and could result in overheating. See Table 1 for the minimum recommended extension
cord length and gauge for 110-120V power. For best performance, use the shortest and heaviest (lowest
numbered) extension cord gauge possible.

Attempting to operate the saw with power
other than 110-120V, or 208-240V if the
motor is re-wired, will void all warranties
and may result in serious injury as well as
damage to, or a malfunction of, the saw or
safety system.
WARNING! This saw must be connected to a grounded wiring system, or to a system having an equipment-
grounding conductor. Failure to connect this saw to an adequate electrical ground may cause the safety
system to malfunction and could result in a serious injury or electric shock.
