POWER CONNECTIONS
A separate electrical circuit should be used for your machines:
FOR SINGLE PHASE UNITS (EXCEPT THE FIVE HORSEPOWER): This circuit should not be less than #12 wire and should be
protected with a 20 Amp time delay fuse.
FOR FIVE HORSEPOWER, SINGLE PHASE UNITS: The circuit should not be less than #10 wire and should be protected with a 40 Amp
time lag fuse.
FOR PERMANENTLY CONNECTED MACHINES: See No. 3 in "GROUNDING INSTRUCTIONS".
If an extension cord is used, use only 3-wire extension cords which have 3-prong grounding type plugs and matching receptacle
which will accept the machine's plug. Before connecting the machine to the power line, make sure the switch is in the "OFF" position
and be sure that the electric current is of the same characteristics as indicated on the machine. All line connections should make
good contact. Running on low voltage will damage the machine. (See "THREE PHASE OPERATION" and "LVC MAGNETIC MOTOR
CONTROL" sections for more information on power connections.)
Do not expose the machine to rain or operate the machine in damp locations.
MOTOR SPECIFICATIONS
All Unisaw motors are rated for 60 HZ alternating current, but voltage and HP varies according to model:
Model:
36-R31, 36-R31X
36-R51, 36-R51X, 36-R51L
36-R53L
Before connecting the machine to the power source, make sure that the switch is in the "OFF" position.
GROUNDING INSTRUCTIONS
1. All grounded, cord-connected machines:
In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric
shock. This machine is equipped with an electric cord having an equipment-grounding conductor and a grounding plug. The plug must be
plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.
Do not modify the plug provided - if it will not fit the outlet, have the proper outlet installed by a qualified electrician.
Improper connection of the equipment-grounding conductor can result in risk of electric shock. The conductor with insulation having an outer
surface that is green with or without yellow stripes is the equipment-grounding conductor. If repair or replacement of the electric cord or plug is
necessary, do not connect the equipment-grounding conductor to a live terminal.
Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether
the machine is properly grounded.
Use only 3-wire extension cords that have 3-prong grounding type plugs and matching 3-conductor receptacles that accept the machine's
plug. Repair or replace damaged or worn cord immediately.
2. Grounded, cord-connected machines intended for use on a supply circuit having a nominal rating between 150 - 250
volts, inclusive:
If the machine is intended for use on a circuit that has an outlet that looks like the one illustrated in Fig. A, the machine will have
a grounding plug that looks like the plug illustrated in Fig. A. Make sure the machine is connected to an outlet having the same
configuration as the plug. No adapter is available or should be used with this machine. If the machine must be re-connected for
use on a different type of electric circuit, the re-connection should be made by qualified service personnel; and after re-connection,
the machine should comply with all local codes and ordinances.
NOTE: In Canada, the use of a temporary adapter is not permitted by the Canadian Electric Code.
In all cases, make certain that the receptacle in question is properly grounded. If you are not sure, have a qualified
electrician check the receptacle.
