Warning! Follow the instructions for inserting the plugs!
Apply anti-grip solution to the threads of the plugs to prevent the nut from getting stuck before it is
completely tightened.
After mounting the mixer, tighten the plugs.
The procedure to check the tightness of the plugs should be repeated after a few days.
For further mounting operations, follow the instructions given in paragraph 8.1 on general instructions.

ELECTRICAL CONNECTION
The mixer is supplied without an electrical panel.
The motor should be started progressively rather than directly (using a soft starter, inverter, etc.), or
using a star delta system. This should allow the mixer to reach the nominal number of revolutions in
approximately 3-5 seconds. Avoid abrupt starts and stops.
Use of an inverter is recommended!
The electrical connection should be carried out in a location free from atmospheric precipitation by qualified
staff in accordance with the directives in force on the subject of safety and accident prevention.
Any specific instructions regarding electrical systems (e.g. sections of cables, safety, connecting a safety
conductor) should also be fully adhered to.
Only use parts which meet regulatory requirements.
Only authorised connections can be made in potentially explosive atmospheres.
The cable must be sufficiently long so as to enable the mixer to tilt; this is because there is a
potential risk of tearing.
The electrical cable must not be placed near the hydraulic directional device or the rotating
parts, because there is the potential for it to get crushed.
The motor must be protected against all circumstances that may cause it to overheat excessively. A dedicated
device should be used for this purpose: e.g. an automatic switch with protection against loss of phase.
The motor is equipped with thermistors (PTC) so that thermal protection from a supplementary machine (TMS)
can be used if necessary.
The motors are protected against dust and water spray depending on their grade of protection. In the event of
ice or snow, further safety precautions must be taken.
The power line to the motor must comply with the information provided on the connection box at the base of the
motor and with the details on the control panel.
In order to safely work on the mixer, an on-load switch capable of disconnecting power to
the mixer itself must be positioned in the vicinity of the mixer (within reach of the
maintenance technician). Alternatively, the automatic switch should be located on the
electrical panel in the equipment room (which safeguards the line connected to the mixer)
and it should be possible to lock this in an open position using a lock, so that the
maintenance technician can keep it nearby during maintenance operations.
