Protect the electric motor from dust as much as possible and keep ventilating openings clean.

CAUTION	Electric Motor
	Safety

DO NOT spray water at any time on the electric motor.

DO NOT operate electric motor in a explosive environment.

The electric motor used in this mixer is a single-phase 3 HP motor. The input voltage requirement for this motor is 115/230 VAC, and has been pre-set to 230VAC.

Electric Motor Connection

A12-inch electrical cable (Figure 7) is provided with the electrical motor for hookup to a power source.Table 5 shows the required NEMA connector for the desired motor horsepower rating. In addition, Table 5 also shows the matching NEMA approved connector for the required extension cord.

CAUTION	Electric Motor
	Connections

ALWAYS make certain that the power source required for the electric motor is correct and always use the correct NEMA configuration plug. Failure to supply the correct voltage to the motor can severely damage the motor.

NOTE It is strongly recommended that all electrical wiring be done by a licensed electrician.

Special attention should be given to the electric switch as well as the over-and-under voltage protection devices as per regulations set forth in the local electrical safety code handbook

ALWAYS, make certain that the power source required for the electric motor is correct and always use the correct NEMA configuration plug. Failure to supply the correct voltage to the motor can severely damage the motor.

The motor supplied is wired for 230 VAC grounded operation. Make certain that the correct size grounded (3-wires) extension cord is used. See Table 6.

Motors can burn out when the line voltage falls 10% below the voltage rating of the motor. Failure to use proper voltage will cause the motor to overheat and actuate the overload switch.
