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.
