Grounding
Vibrator must be grounded using power supply ground wire.
Failure to properly ground vibrator can cause severe injury or death.

Amps Reading
Using an amp meter, check that the current absorbed in the three phases
is lower to the amps indicated in the nameplate

Connection to Power Supply
This operation must be executed by qualified personnel only.
Power supply must be disconnected during installation!
Use flexible cable, with 4 leads.
Cable section must be appropriate for motor amps draw (max. density = 4A/mm2)
Cable grip should match the cable size in order to prevent water or humidity from entering the terminal block. Allow for voltage drop for cables exceeding recommended length.

When running the cord to the vibrator, make sure the cord voltage rating equals or exceeds the voltage at which you will be operating the vibrator. It must have a minimum temperature rating of 220° F and a minimum diameter
(as shown in the table above)

If the wire does not have the right diameter, the cord grip will not tighten properly and the vibrator could be damaged by moisture or material getting into the terminal block. If the cord is damaged, it could short the power supply or short to ground causing damage to the vibrator.

When wiring vibrator, leave slack in electrical cable so that cable does not become too tight during vibration cycle causing stress on wire connections and preventing moisture form running down the cable into the terminal block.

For equipment using two vibrators, the two motors must be electrically interlocked. If using a single contactor, each motor must be provided with separate overload protection. The motor control circuit must be arranged so that if one motor becomes de-energized, the other motor will automatically and immediately become de-energized.

 

Incorrect Voltage
Even a 5% difference on a larger motor could have a negative effect.

Besides a thorough maintenance and testing program, one of the best ways to guarantee economical performance and long motor life is to make sure your motors operate at nameplate voltage.
Applying a higher voltage may reduce the motor's efficiency and increase core losses.
This, in turn, shortens the motor life by overheating the insulation system.

Low voltage can also shorten motor life. Operating on too low a voltage reduces the motor's effective horsepower. For example, a 5-hp motor operated at 10% below rated voltage becomes a 4-hp motor. The motor will try to drive the load it was intended to drive, become overloaded, draw more current and overheat. The result -- premature failure.

Voltage Fluctuations
Voltage fluctuations due to poor power supply or wrong cable size need to be kept under control.
Frequent or extended voltage variations can be fatal for the motor.
Proper safeguards should be installed.

Voltage Unbalance
Unbalance also can be lethal for the motor.
Operating a three-phase motor with an unbalanced voltage can also cause serious overheating
that will shorten its life dramatically.
Voltage unbalance should not exceed 2%.

Moisture
Moisture is detrimental to long motor life because it will deteriorate the insulation. To prevent condensation, one of two common methods are usually effective. One is to install electric heaters in the motor. The other is to apply a low dc voltage to one phase of the motor windings whenever the motor is at rest. With either method, the objective is to keep the temperature of the windings 10°F to 20°F above the ambient temperature.
Protect electric vibrators from excessive water. This series is not designed to operate submerged.

Insulation
Class F insulation enhances the safety under continuous operating conditions and at high ambient temperatures.
The motor winding is drip impregnated with synthetic resin to withstand high "g" forces.
Mechanical protection IP 65-7
