3.2.1 ELECTRICAL CONNECTION
Any elctrical intervention involving the working site is to be carried out by qualified and skilled technicians,
having a technical knowlege and a knowlegde of the standards concerned to carry out operation properly
done and on safety conditions according to the existing laws and standards; they shall be able to issue the
declaration of conformity concerned and required by the law. After delivering the machine and before
proceeding to the electrical connection,
ensure that voltage, frequency and number of phases are the
same declared by the Manufacturer and shown on the identification plate;
voltage, frequency and
number of phases are also reported on a adhesive label placed at the back of the machine, in vicinity of the
point where the power supply cable enters the base.
In any case, refer always to the technical
specifications shown on the identification plate only
(paragraph 2.5).
The machine is delivered complete with cable and 4-pole plug ( 3-phase poles + 1 ground pole PE); see
Picture 11.
Use the ground system concerned , the efficiency of which has to be periodically tested and do not connect
to any gas or water pipes or other generic metallic structures .
For connections in the US/Canada:
An electrician licensed under the jurisdiction (city, municipality, county, state, etc.) in which the mixer will be
installed must install the plug that meets requirements in sub-clauses 4.5.2.2 of C22.2 No. 195
and 6.2.1, 11.1.1, 15.1.6 of UL 763.
The power supply cable is to be kept far of warm parts and/or parts in motion and has not to be an obstacle
for people, animal or things.
The plug has to be easily accessible and as visible as possible too.
Once the plug has been connected to the power supply socket, check the correctness of the bowl and spiral
arm rotation direction: i.e.
clockwise
on normal conditions (overhead view); if the rotation direction is not
correct, invert the two phases in the plug ( do not disconnect the ground cable from its clamp)
but this
operation has to be carried out by a professionally qualified electrician only
.
