Introduction
Italvibras USA stainless steel industrial electric vibrators have been designed and manufactured
in accordance with the most exacting international industrial standards and requirements.
Italvibras USA industrial electric vibrators are constructed of AISI 316 stainless steel. They
are designed for long life at continuous duty and maximum force output. The electric vibrators
are suitable for operation in ambient from -30°C to 40°C (operation outside of this range needs
engineering consideration).
Italvibras USA industrial electric vibrators have been evaluated for installation throughout the
world. Standard ratings include CSA (Canadian Standards Association) Approval, the CE
(European Directive) Mark, EX Approval for Zone 21 (ATEX II2D tD A21 IP66) and Russian
GOST Mark. Check the electric vibrator nameplate for the exact ratings and Approvals for the
specific Model.
The electric vibrator can be referred to by its Model or Type designation or by its Item number.
The vibrator Model or Type designations referred to in this manual are as follows:
MVSS – Continuous duty stainless steel industrial electric vibrator, single or three phase.
General Safety requirements
Read this entire manual before proceeding. Compliance with all company, local and OSHA
regulations is essential. Any electrical work must be done in accordance with all applicable
local and national codes and must be performed only by qualified, licensed and authorized
personnel. Always follow lockout and tag out procedures and requirements and always wear
ear protection when in close proximity to operating vibratory equipment.
Comprehensive adherence to these documents at a minimum is required – The National
Electrical Code NFPA 70, ANSI z244.1 the American National Standard for Personnel Protection
– ockout/Tag out of Energy Sources – Minimum Safety Requirements, CFR 29 Part 1910 –
Control of Hazardous Energy Sources ( ockout/Tag out) Final Rule and CFR 29 Part 1910.15
Occupational Noise Exposure.
Storage
Storage of the electric vibrator should be in an ambient not less than 5°C with a relative
humidity not more than 60%. If the vibrator has been stored for longer than two years, the
vibrator should be evaluated by authorized and trained personnel to ensure that the grease is
intact, that there is no bearing damage such as brinelling and that the ground insulation is
sound and not damaged from condensation.

Installation
Before installing the vibrator, make sure that you have everything that you will need and that
there is no shipping damage. Any product damage should be reported to the delivery service
immediately. Standard metric hand tools will be needed. Carefully handle the electric vibrator.
Dropping or impacting the electric vibrator may damage the bearings.
Welding – Never weld on a bin, hopper or machine with the electric vibrator mounted to it
since the welding may damage the vibrator bearings or electrical circuits. When you do weld,
especially in an enclosed area, make sure that the area is known to be nonhazardous and that
there are no flammable or explosive levels of gases, vapors or dusts.
Mounting Surface – The object of vibration on bins and hoppers is to transmit vibration energy
through the structure to the material within. The mounting surface must be rigid and strong for
this transfer of energy to take place. The mounting surface must also be clean, flat (0.010 in.
across mounting feet maximum), free of paint and have a minimum thickness equal to the
major diameter of the mounting bolt. Also make sure that the electric vibrator feet are clean
and free of debris.
Mounting Plate
The mounting plate should be at least the overall size of the electric vibrator feet. It should be
located on the bin and hopper wall at a height of ¼ to 1/3 of the sloped wall height. The
mounting plate or bracket should extend at least ¾ the length of the sloped wall. Reference
Figure 1. If a second electric vibrator is to be installed to the bin or hopper, install it at a height
of ½ of the sloped wall height and 180° from the first vibrator. Weld the mounting plate or
bracket to the structure wall with skip welds that are 3 in. long then skip 2 in. then 3 in. long
weld, etc. Do not weld at corners of mounting plate within 1 in. of the corner.
Figure 1. Mounting Examples

Safety Cable
Always install a safety cable metal rope from the electric vibrator to a reliable support should
the vibrator become free from its mount and fall more than 6 in. The metal rope should be taut
and positioned above the electric vibrator. Reference Figure 2.

Mounting Kits
Mounting kits are available from Italvibras USA for frame sizes 00, 01, 10, 20, 30, 40 and 50.
The mounting kits include a channel mount with integral mounting plate, mounting screws
and washers and safety cable kit. Contact Italvibras USA by phone at 815-872-1350.

Mounting Hardware & Torque
Always use new bolts, nuts and compression washers. The bolts should be Grade 5 or 8
(equivalent international designation is 8.8 and 12.9, respectively). Grade 5 bolts are suitable
for a majority of applications. Do not use split lock washers. Use only compression washers.
Table I offers suggested mounting bolt torque values. Always check with the bolt manufacturer
for recommended torque values. Torque the mounting bolts in the proper sequence as shown
in figure 3 so as not to damage casting. After operating vibrator for 15 minutes, disconnect,
lockout/tag out, and torque the mounting bolts a second time. Periodically check the mounting
bolt torque thereafter.

Wiring Electric Vibrator
It is mandatory to comply with the National Electrical Code, NFPA 70, and all applicable local
codes. Identify which wiring diagram is applicable by referencing the Diagram designation on the
nameplate or by referring to Table II. Remove the four screws with washers securing the wiring
box cover along with the foam rubber block and set aside. Identify the wiring diagram by
referencing the predetermined Diagram noted on the wiring diagram found within the wiring box
or by referring to the Diagrams shown in Figure 4.

Wiring Electric Vibrator Cont.
Trim the conductors within the wiring box leaving plenty of slack. Next, strip the conductor
insulation for 1/4 in. to 3/8 in. Crimp on closed loop wire connectors. Use only the intended
crimping tool as designated by the wire connector manufacturer. The conductors should be
neatly arranged on the floor of the wiring box. The wires should not cross over each other. See
figure 6.
When wiring the electric vibrator, leave enough slack in the cord so that the cord does not become
taut during operation causing stress on the connections. It is always best to position the cord down
so that should there be any moisture present the moisture would tend to run down instead of into
the vibrator wiring box.
Trim the cord by removing the jacket exposing the conductors and ground wire for approx. 6 in.
Be careful not to cut the conductor or ground wire insulation. oosen the compression nut from
the cord fitting assembled to the side wall of the wiring box on the electric vibrator. Position the
compression nut on the cord and insert the cord through the opening in the side wall of the wiring
compartment. Position the jacket of the cord approx. ½ in beyond the inside wall of the wiring box
wall and secure the compression nut by threading it to a position equal to the “Distance Between
Flats” noted in Table III. Reference figure 5. which pictorially defines “Distance Between Flats”

For wiring diagrams 1A, 1E, 2Aand 2C (Fig.4), reinstall the rubber block over the power supply
conductors and install the wiring box cover being careful not to pinch the O-ring. Screw torque
is specified in the Appendix. See figure 8.
For wiring diagrams 5A and 5B, you will note that there is a small 2-pole terminal block in the
wiring box. This is the thermistor circuit. Proceed to Thermistor Wiring.
Figure 8. Wiring Block Assembly
Figure 7. Terminal Block Hardware Installation
Secure the wire connectors and the shorting bars to the terminal block in the positions shown
on the wiring diagram using the hardware provided. It is essential that the hardware be
positioned as shown in Figure 7.
Note that the closed loop wire connectors provided on the power supply cord are positioned
between the two flat washers. A drop or two of thread sealant such as ocktite is recommended.
Do not use permanent thread sealant because the terminal block will be damaged should you
wish to remove and replace the power supply cord. The terminal block nuts should not be over
tightened since the possibility of damaging the plastic insulating body is high. Reference table
VI in the Appendix for torque values. Make the connections hand-tight followed by a ¼ turn
but never put a ratchet on these nuts.
