3.1 INSTALLATION

3.1.1 INSTALLATION ZONE
CDX frame size 110 electric vibrators can ONLY be installed
in potentially explosive atmosphere related to the equipment
category, as listed in page 3.
To assure the correct use of CDX electric vibrators in the right
zone, the user has to have knowledge of the details in following
standards and laws:
Europe
- EUROPEAN COMMUNITY DIRECTIVE 94/9/EC
- CENELEC EN 60079-14, EN 60079-10.
U.S. & Canada
- The National Electrical Code (NEC), article 500
- American National Standards Institute (ANSI) z244.1-1982
- Code of Federal Regulation (CFR) 29, Part 1910, Part 1910.15
- Canadian Electrical Code (CEC).
other than all Standards and Law for potentially explosive atmosphe-
res, of the country where the vibrator is used.

3.1.2 INSTALLATION ON VIBRATING MACHINE

ITALVIBRAS vibrators can be installed in any position.
The vibrator must however be fixed to a perfectly flat surface (within
100inch. (0,25mm) across vibrator feet) (Fig. 2, page 4) using bolts
(quality 8.8 - DIN 931-933) and nuts (quality 8.8 - DIN 934) which
are able to support high coupling torques (Fig. 3, page 4).
Use a dynamometric wrench (Fig. 3, page 4) adjusted according to
that stated in the "Coupling torque" table on page 80.
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 81.
It is also indispensable to control that the bolts are tightened fully
home.
This control is particularly necessary during the initial functioning
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 recommended 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 inch.)
(Fig. 7, page 4).
Attention: Do not carry out welding to the structure with the
vibrator mounted and connected. Welding could cause damage
to windings and bearings.
Warning: 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.
Attention: Use new bolts, lock nuts, and lock washers when
installing vibrator. Do not reuse old fasteners. Damage to
vibrator or structure could result.
3.2

ELECTRICAL CONNECTION

All wiring must be made in compliance with the National
Standards and with the Laws in force in the country of use, with
particular reference to the standards and legislations in force
for explosive environments (protection mode "d").
The wiring must be made by specialized electricians.

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.
The wires making up the power supply cable used to connect the
vibrator to the network must have an adequate section so that the
current density, in each wire does not exceed 4 A/mm
is used exclusively for the connection of the vibrator to earth.
The section of the wires must also be adequate for the length of the
cable used so that a drop voltage along the cable is not caused that
exceeds the values prescribed by the regulation on this subject.
The conductors forming the power supply cable connecting
the motor vibrator to the electricity main, must be of suitable
section.
Use a power cable able to withstand temperature exceeding
105°C.
