The user must ensure that the system inside which the electric motovibrator will be installed has been suitably made safe against
explosion hazards before it is started and that the "document on protection against explosions" has been prepared as set forth by ATEX
directive 2014/34/EU.
-The machine does not need any particular lighting. However, the machine installer is required to ensure uniform lighting in the area
according to the relevant regulations.
THE MOTOVIBRATOR MUST BE INSTALLED BY SPECIALISED PERSONNEL ONLY.
Before installation, especially if the appliance has been stored in the warehouse for a long time (more than 24 months), we recommend
removing one of the side protection covers of the exposed conductive parts and checking that the shaft rotates smoothly.
Also check the insulation of the motor by means of a "Stiffness Test" at about 2 KV for no more than 5 seconds between each phase and 10
seconds between the phase and the earth. (Fig.3)
Contact the manufacturer if you detect any faults.
The MVE motovibrator can be installed in any position. We recommend fastening the vibrator to a rigid area to prevent the induced
vibrations from causing failures or cracking. If this is not possible, reinforcement plates and ribs must be used . Cutting and welding
procedures must be carried out by qualified personnel. Suitable Hot-Works procedures (such as cutting, welding, etc.) and LOTO – lockout/
tagout: procedure to disconnect the machine (electrical and mechanical segregation) must be applied to safely install the electric vibrator.
The authorisation to perform the hot works must be given by specialised technical personnel with training on the risk of an explosion due
to dust (who can check the residual risk, suitability of the tools and have knowledge of procedures).
The connection surface must be flat (max 0.25 mm/max 0.01 in.), so that the feet of the vibrator rest evenly and perfectly adhere to the
fastening surface to avoid internal tension that can lead to breakage of the motovibrator feet (Fig.4-4a-4b-5).
To secure the motovibrator, use bolts (8.8), nuts (8.8) and flat washers cat. A EN ISO 7089 / 7092 as specified in the table of the TAB section
from page TAB.166 to page TAB.173
Use a torque wrench set in accordance with the tables in the TAB section from page TAB.166 to page TAB.173
Bear in mind that most failures are due to fastenings and tightenings that have not been performed correctly.
Anchor the motovibrator with a chain whose length and section can hold up the motovibrator with a maximum fall of 15 cm (6 inches) in
the event of an accidental detachment. (Fig.6)
Check before starting the equipment and after the first 24 hours of operation:
- The motovibrator fixing bolts and welds of the reinforcement plates and ribs.
- The anchoring cable or chain.
- The power supply cable.
