Safety regulations
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 damage 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 opportune
safety precautions to reduce the risk of fire, electric shock and injury
to persons. Therefore, before using the vibrator, carefully read and
memorize the following safety regulations. After reading, preserve
this manual with care.
- When using this electric vibrator, all safety rules defined for potentially
explosive atmospheres have to be strictly followed, other than all standards
and safety law and regulations of the country where the vibrator is installed
and used.
- Maintain the work area clean and in order. Untidy areas and environments
favor accidents.
- For repairs and overhauls, it is necessary to contact Italvibras - Fiorano
Modenese (Italy) directly or an Italvibras dealer who will contact Italvibras
- Fiorano Modenese (Italy).
- 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 authorized, trained staff.
- Repair, or have repaired by unauthorized staff, means, operating with
unsafe and potentially dangerous equipment as well as loss of 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.
- It is prohibited for children, unauthorized persons, unskilled persons 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 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 authorized, 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 unauthorized persons to touch the cable with
the plug inserted.
- If the insertion of a vibrator onto a machine causes the sound level, esta-
blished 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 particularly
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 authorized 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 Manufac-
turer. 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
- Dimensions of flameproof joints are other than relevant minimum
or maximum specified in Table 2 of EN 60079-1:2014. Vibrators are
marked with an "X" and manufacturer's drawing numbers 601297,
601296, 601294, 601293, 601332, 601292, COMPL-94-40-IMX/VMX,
COMPL-94-40-EX, COMPL-02-35-EX, COMPL-94-80-IMX/VMX, and
COMPL-94-80-EX detail the dimensions of the flameproof joints.
- For frame size 35 the admitted input voltage is between 95% and
105% of rated voltage, for all other frame sizes tests were performed
under the most adverse ratings with an input voltage between 90%
and 110% of the rated voltage.
- The fasteners are property class 8.8.
- The cable fastening must be made direct near the cable entry.
- All accessories associated to the vibrator to ensure smooth operation
and safety must provide a recognized protection type, adapted to
their specific use.
- See instruction manual for guidance for the user to minimize the risk
from electrostatic discharge.
- All cable entry devices and closing elements must be certified for
the type of flameproof enclosure "db", suitable for the conditions of
use and correctly installed.
Unused openings must be closed with suitable locking elements as
indicated above.
- Minimize the risk of electrostatic discharges: it is recommended to
avoid the formation of dust on the vibrator, periodically remove dust
deposits, to avoid electrostatic discharges. Clean with a damp cloth
to avoid danger.
- In the vibrators equipped with a temperature limiting device (PTC or
thermal), remember to connect it following the instructions in this
manual.

Handling and installation
The vibrator may be supplied without packaging or palletized according to
its type and size.
To handle the unit, if palletized, use a forklift truck or trans-pallet with forks.
If it is not packed exclusively use the rods or hoisting eye-bolts (Fig. 1,
page 6).
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 tech-
nical datasheet.
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.4, page 6) and check
that the shaft turns freely (Fig. 5, page 6).
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 kVa.c. and for a time that does not exceed 5 seconds between
phases and 10 seconds between phase and earth (Fig. 6, page 6).
If anomalies result from the control, the vibrator must be sent to an ITALVIBRAS
Assistance Centre or to ITALVIBRAS itself, for restoration of efficiency.
