Electric Motor
For maintenance care and operation of the electric motor,
refer to your electric motor instruction booklet furnished with
the motor.
Protect the electric motor from dust as much as possible
and keep ventilating openings clean.
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
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
A 12-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.

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.
