Electric Motor - MULTIQUIP EM90SH8 Manual

This mixer is equipped with a single-phase, 3-horsepower,
230 VAC electric motor (Figure 11).
Figure 11. Electric Motor
For operation and maintenance of the electric motor, refer to
the electric motor instruction booklet provided with the motor.
Protect the electric motor from dust as much as possible
and keep ventilating openings clean.
CAUTION
DO NOT spray water on the electric motor at any time.
DO NOT operate the electric motor in an explosive
environment.
ELECTRIC MOTOR POWER CONNECTION
WARNING
ALWAYS make sure that the correct voltage is supplied
to the motor. The input voltage requirements can be
found on the electric motor's nameplate. Applying
incorrect power to the motor can severely damage the
motor and may cause serious bodily injury!
NOTICE
It is strongly recommended that all electrical wiring
be performed by a licensed electrician. Pay special
attention to the nameplate on the electric motor. Make
sure the voltage supplied to the electric motor matches
the required operating voltage printed on the nameplate.

ELECTRIC MOTOR

A 12-inch electrical cable (Figure 11) is provided with the
electric motor for connection to a power source. Refer
to Table 6 for the correct NEMA connector for the power
cable and the matching NEMA connector for the required
extension cord. Make sure that a correctly sized, grounded
(3-wire) extension cord is used. See Table 7.

The electric motor is configured at the factory for 230 VAC
grounded operation. Due to high amperage when mixing,
it is recommended to use only 230 VAC.
Motors can burn out when the line voltage falls 5% below
the voltage rating of the motor. Failure to use proper voltage
will cause the motor to overheat and actuate the overload
switch.
If overload protection should actuate because of improper
voltage or any other malfunction, turn the main switch on
the motor to the OFF position, correct the problem, press
the reset switch button, then turn the main switch back to
the ON position.
NOTICE
ALWAYS make sure the electric motor's ON/OFF switch
is working properly. When the mixer is not in use, place
the ON/OFF switch in the OFF position and disconnect
the power cord from the power source.
CAUTION
NEVER disable or disconnect the ON/OFF switch on
the electric motor. It is provided for operator safety.
Injury may result if it is disabled, disconnected or
improperly maintained.
