I. PREPARATION
D. Electrical Connections
Important-Before connecting the motor leads to the power supply be sure that the
voltage, cycles and phase shown on the nameplate of the motor correspond to the
available power supply.
Voltage Selection For Single Phase Motors
1-1/2 h.p. and 2 h.p. single phase masonry saw motors have a dual voltage capable. A 115-
volt or 230 volt power supply can be used. To change voltage simply move the voltage
change switch located on the front of the motor to the required voltage, no rewiring is required.
Wherever possible, use 230-volt power supply for best operation.
Failure to run the motor on the proper voltage will damage the motor and is not
covered under warranty. Improperly wired motors are not covered under warranty.
Saws are wired for 115 Volt from the factory!!!
Power Connections
Connect the power supply to the pigtail leads of the switch. Direct wiring connection is
preferred, but an extension cord with an electrical plug with 30-amp minimum capacity may be
used. A 30-amp circuit breaker is recommended. Connecting wires should be as short as
possible and in one piece. In no case should the connecting wires be longer than shown in the
following table for 1-1/2 and 2 h.p. Single-phase motors:
LENGTH OF WIRE
WIRE GAUGE 115 VOLT 230 VOLT
NUMBER 12 25 FEET 100 FEET
NUMBER 10 50 FEET 150 FEET
NUMBER 08 75 FEET 175 FEET
Caution-When wires that are too small gauge or too long are used, loss of power, over
heating, or possible damage to the motor will result.
Always use the proper wiring connectors that are UL/CSA approved to attach the
motor to the electrical supply. Any wiring hook ups should be made by qualified
personal and made to National Electrical Code and to any Local Codes.
Generators:
If a generator must be used, it must be of 8kW or larger. The generator must have a 30A
circuit and capable of providing a minimum of 8kW at the required voltage. Under size
generators will cause motor damage and is not covered under warranty.
