Pay attention to the danger signal present in this manual; it prece-
des the signal for a potential danger.

2.1 GENERAL SAFETY REGuLATIONS

When using electrical equipment, it is necessary to adopt opportu-
ne 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.
- When using this electric vibrator, all safety rules defined here below
have to be strictly followed:
European union
- EuROPEAN COMMuNITY DIRECTIVE 94/9/EC
- CENELEC EN 60079-14, 60079-17.
and all Standards and Safety Law of the country where the vibra-
tor is used.
- Maintain the work area clean and in order. Untidy areas and environ-
ments 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 war-
ranty.
- Do not touch the vibrator when functioning.
- Any type of check, control, cleaning, maintenance, change and pie-
ce replacement, must be carried out with the vibrator and machine
switched off with the plug disconnected from the socket.
- It is prohibited for children, unauthorised persons, unskilled persons
and persons who are not in good health to touch or use the vibrator.
- Check the plant power supply is in compliance with the regulations.
- On installation, check that the power supply cable is very flexible and
ensure that the earth is connected.
- 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 cor-
ners. 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 level,
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 particu-
larly 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.
- 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 Ma-
nufacturer. The Manufacturer is however at complete disposal to
ensure immediate and accurate technical assistance and all that
is necessary for good functioning and maximum performance of
the vibrator.

2.2 SPECIAL CONDITIONS FOR SAFE uSE

Use ATEX certified cable gland in accordance with appropriate ser-
vice temperature and having a minimum IP66 degree of protection.
The surface temperature determination was based on operation
within "zone A" (EN 60034-1), typically ±5% of rated voltage.
The thermistor (or thermal protector) is installed starting from fra-
me size MA. The connection of this thermal protection is mandatory
for dust potentially explosive atmospheres (zones 21-22).

SECTION 3 – Handling and installation
The vibrator may be supplied without packaging or palletised according
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.
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 8.
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 dama-
ge 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 and check
that the shaft turns freely.
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 0 seconds between phase and earth.
If anomalies result from the control, the vibrator must be sent to an Ve-
nanzetti Vibrazioni Milano Assistance Centre or to Venanzetti Vibrazioni
Milano itself, for restoration of efficiency.
