tightened with the “half nut turn” method: tighten the screws until the surfaces come completely into
contact, sign the screws and the nuts and then tighten the nuts down completely half a turn ( 07-10).
WARNING
Carefully check the proper tightening torque of the fastening screws to prevent damage to the
Vibrator and to people and /or things.
WARNING
Connect the Vibrator to the unit by means of a steel cable to prevent the machine from falling
due to accidental detachment.
7.3
Electrical connection
WARNING
Each Vibrator must be provided with adequate protection against short- circuit (magnetic) and
current overload (thermal), adjusted according to the value indicated in the identification plate.
(Fig.02-02). In case the application of two Vibrators is required, each one must be equipped
with its own protection feature and interconnected with one other (Fig.07-11).
NOTE
The Vibrator is to be fed through a “flexible” cable bearing characteristics compliant with those
indicated in the IST table at chapter 13.3.
NOTE
In case the distance between the machine and the distribution panel is greater than 20 (twenty)
meters, utilize an increased feed cable to avoid a drop in tension at the Vibrator terminal block
during start-up.
NOTE
The value of the feed cable bending curve, in proximity to the Vibrator, must be no lower than
that indicated in the IST tables at chapter 13.3, to prevent damage due to vibrations generated
during machine operation (Fig. 07-12).
NOTE
In case the cable gland needs to be replaced, make sure the new one is compliant with the
grade of protection prescribed for the Vibrator indicated in the identification plate.
Remove the terminal block cover and the cable gland buffers, then loosen the ring nut of the feed
cable gland and thermistor (where foreseen) (Fig. 07-14).
Introduce the feeding and the thermistor connection cables (where foreseen) into the respective
cable glands (Fig. 07-15).
Properly apply the ring and tip terminals to the conductors.
Carry out the connection in the terminal block according to the diagram shown in the sheet (located
inside the terminal block), corresponding to the code shown on the identification plate (07-16).
