Venanzetti vibrators can be installed in any position.
The fixing area must be rigid to prevent the vibra-
tions from causing breakages owing to high stress.
Reinforcing plates and ribbing may be required.
The surface to which the vibrator is connected must
be flat to ensure a perfect contact for the fixing feet
and to prevent the supports from breaking or the bolts
from slackening off. Once these conditions have been
ensured, install the vibrators with flat spring safety
washers, bolts, nuts and check nuts of a correspond-
ing diameter, i.e. size 8.8 or more.

ATTENTION ATTENTION ATTENTION ATTENTION ATTENTION
If installation is done in enclosed area, gas level
or dust content must be tested before welding.
Welding in an area with gas or dust may cause
an explosion.
CAUTION CAUTION CAUTION CAUTION CAUTION
Never weld structure with vibrator mounted and
wired. Welding will cause damage to motor
windings and bearings.
CAUTION CAUTION CAUTION CAUTION CAUTION
Use new bolts, lock nuts, and lock washers
when installing vibrator. Do not reuse old
fasteners. Damage to vibrator or structure could
result.
ATTENTION ATTENTION ATTENTION ATTENTION ATTENTION
The installed electric vibrators must be connected
to a steel safety wire with sufficient diameter and
length to hold the vibrator if it accidentally
detaches and permit it a maximum fall of 15 cm
(6 inches).
After the vibrator has operated for several hours, the
fixing bolts will need to be torqued again. Periodically
ENGLISH
check to make sure that all the bolts are well tight-
ened even when none have appeared to have slack-
ened off when the re-torquing operation is carried out.
The elastic system should be sized in the correct
way. Failing this, the electric vibrators could reach a
lower spinning speed (rpm) than that forecast for con-
tinuous service owing to certain ratios between the
operating frequency and the natural frequency of the
elastic system in which the vibrator is applied. The
elastic characteristics of the system must be modi-
fied in these cases, to prevent damage to the elec-
tric parts of the vibrators.

ATTENTION: The terminal box (and the vibrator
external surface) has a tropicalized screw bearing a
plate stamped with symbol
conductor of the power supply cable must be
connected to this screw which acts as a earth
connector for the vibrator.
SPECIAL CONDITIONS FOR SAFE USE
The cable fastening must be made direct near the
cable entry.
All accessories associated to the vibrator motor
to ensure smooth operation and safety must
provide a recognized protection type, adapted to
their specific use.
User must looked after regularly of good bearings
conditions, and in any case exceed the bearing
life estimation defined by manufacture in pages
8 and 9.
The wiring diagram is inside the terminal box. The
pertinent wiring diagram is indicated on the name-
plate.

pairs pairs pairs pairs pairs, it is important to ensure that each one has its
own external protection against overloads and that
these protections are interlocked together. Should
one vibrator accidentally stop, power supply to both
machines would be inhibited at the same time to
prevent damage to the equipment to which they are
connected, consult Fig. 6, page 3 as examples of
power and control circuit.
