2.0 SAFETY
Careful reading of this manual is highly recommended, the safety
regulations in particular.
Pay great attention to dangerous operations.
The Manufacturer declines all liability for non-compliance to
safety regulations and to accident-prevention prescriptions
described below. It also declines any responsibility for dama-
ge caused by improper use of the vibrator or by unauthorised
modifications.
Pay attention to the danger signal present in this manual; it
precedes the signal for a potential danger.

2.1 GENERAL SAFETY REGULATIONS

When using electrical equipment, it is necessary to adopt op-
portune safety precautions to reduce the risk of fire, electric
shock and injury to persons. Therefore, before using the vibrator,
carefully read and memorise the following safety regulations.
After reading, preserve this manual with care.
- Maintain the work area clean and in order. Untidy areas and
environments favour accidents.
- Before starting work, check the perfect integrity of the vibrator
and the machine to which it is applied. Check normal functioning
and that no elements are damaged or broken. The damaged or
broke parts must be repaired or replaced by authorised, trained
staff.
- Repair, or have repaired by unauthorised staff, means, operating
with unsafe and potentially dangerous equipment as well as loosing
the warranty.
- Do not touch the vibrator when functioning.
- Any type of check, control, cleaning, maintenance, change and
piece replacement, must be carried out with the vibrator and
machine switched off with the plug disconnected from the socket
(Fig. 2, page 8).
- It is prohibited for children, unauthorised persons, unskilled per-
sons and persons who are not in good health to touch or use the
vibrator.
- Check that the plant power supply is in compliance with the re-
gulations.
- On installation, check that the power supply cable is very flexible
and ensure that the earth is connected(Fig.3, page 8).
- Check that the plug socket is suitable and in compliance and has
an automatic protection switch incorporated.
- Any extension of the electric cable must have plugs/sockets and
cable with earth circuit as envisioned by the regulation.
- Never stop the vibrator by removing the plug from the socket and
do not pull the cable to remove the plug from the socket.
- Periodically check integrity of the cable. Replace it if not integral.
This operation must only be carried out by authorised, trained
staff.
- Only use admitted and marked extension cables.
- Protect the cable from high temperatures, lubricants and sharp
corners. Prevent coiling and knotting of the cable.
- Do not allow children and unauthorised persons to touch the cable
with the plug inserted.
- If the insertion of a vibrator onto a machine causes the sound le-
vel, established by the regulations in force in the country in which
it is to be used, to be exceeded, operators must use adequate
protection to protect their hearing e.g. earphones.
- Even if vibrators are planned to work at low temperatures, in par-
ticularly hot environments the temperature of the vibrators may
reach very high values which are induced by the environment
itself.
Wait for the vibrator to cool before intervening (Fig. 4, page
8).
- Only authorised tools that are described in the instructions or shown
in the Manufacturers catalogue can be used. Ignoring this advice
means operating unsafe and potentially dangerous equipment.
- Repairs must only be carried out by staff authorised by the
Manufacturer. The Manufacturer is however at complete di-
sposal to ensure immediate and accurate technical assistance
and all that is necessary for good functioning and maximum
performance of the vibrator.
- For vibrators without weight covers (as those listed on page 89)
the user must prevent persons or foreign bodies from coming into
contact with the eccentric weights during functioning.

Handling and installation
–
The vibrator may be supplied without packaging or palletised accor-
ding to its type and size.
To handle the unit, if palletised, use a forklift truck or transpallet with
forks. If it is not packed exclusively use the rods or hoisting eye-bolts
(Fig. 5, page 8).
If the vibrator must be stored for a long period of time (up to a max.
of two years), the storage environment must have an environmental
temperature that is not less than +5°C and with relative humidity not
exceeding 60%.
After two years storage of vibrators with roller bearings re-greasing
must take place according to the quantity of re-lubrication indicated
in the table on page 94.
After three years storage of vibrators with ball bearings the bearings
must be completely replaced; for vibrators with roller bearings the
old grease must be entirely removed and replaced completely with
new grease.
When handling the unit avoid blows or vibrations to prevent
damage to the rolling bearings.

3.0 BEFORE INSTALLATION

If the vibrator has been stored for a long period of time (more than 2
years), before installation remove one of the weight covers (Fig. 6,
page 8) and check that the shaft turns freely (Fig. 7, page 8).
The electrical insulation of every individual phase to earth, and
between phases, is necessary and indispensable.
To control electrical insulation only use the Megger Insulation Tester
at the test voltage of 2.2 Kv ac and for a time that does not exceed
5 seconds between phases and 10 seconds between phase and
earth (Fig. 8, page 8).
If anomalies result from the control, the vibrator must be sent to an
ITALVIBRAS Assistance Centre or to ITALVIBRAS itself, for resto-
ration of efficiency.
3.1 INSTALLATION
ITALVIBRAS vibrators can be installed in any position.
ATTENTION: MVSI series special vibrators with 600 - 720 rpm.
may only be used in a vertical position with maximum angle of
incidence (α max) as shown in the table on page 89.
The vibrator must however be fixed to a perfectly flat surface (Fig. 9,
page 8) using bolts (quality 8.8 - DIN 931-933), nuts (quality 8.8 - DIN
934) and flat washer 300HV (DIN 125/A) which are able to support
high coupling torques (Fig. 10, page 8). Use a dynamometric wrench
(Fig. 10, page 8) adjusted according to that stated in the "Coupling
torque" table on page 113.
The diameter of the bolt, on the basis of the type of vibrator to install,
must correspond to that indicated in the table on page 94.
It is also indispensable to control that the bolts are tightened fully
home. This control is particularly necessary during the initial func-
tioning period.
Remember that most damage and faults are due to irregular
fixing or badly performed tightening.
Re-control tightening after a brief functioning period.
It is advised to fix the installed vibrator to a steel safety cable, with
opportune diameter and a length that will support the vibrator in the
case of its accidental detachment. Max. fall of 15 cm (6") (Fig. 11,
page 8).
