SPECIFIC WARNINGS / The electrical
safety of this unit is assured only when
it is correctly connected to an efficient
earthing system as stated in the electri-
cal local safety regulations in force; the
Manufacturer declines any responsibility
for the non-compliance with these sa-
fety regulations.It is necessary to verify
this fundamental safety requisite and, in
case of doubt, ask for an accurate testing
of the system by professionally qualifi ed
personnel.The Manufacturer cannot be
deemed responsible for any damages
caused by the lack of unit earthing.
Never interrupt the earth wire
(Yellow-Green).
CONNECTION TO THE DIFFE-

NETWORKS / see SECT. IMAGES
- REF. d)
If necessary, remove the terminal
box protection panel located on
the back of the machine.
The equipment is delivered to work with
the voltage indicated on the technical la-
bel attached on the appliance. Any other
connection is to be considered improper
and therefore dangerous.
It is mandatory to respect the
connection provided by the
manufacturer, visible on the
connection label near the termi-
nal board.
It is forbidden to modify the wir-
ing inside the equipment
ELECTRICAL CONNECTION OF
THE CABLE TO THE TERMINAL BO-
ARD / Connect the power cable to the
terminal board as described in: "Power
supply connection" and indicated on the
connection plate.. The diagram and the
table (see Technical data) indicate the
possible connections according to the
mains voltage.
CONNECTION TO "EQUIPOTEN-
TIAL" SYSTEM - see SECT. IMA-
GES - REF. e) / The protective ear-

thing consists of a series of contrivances,
which ensure the same earth potential in
the electrical earths, thus preventing the
same earths from being tensioned.
The earthing has the aim to ensure that
the earths of the household appliances
have the same potential of the earth.
Earthing also makes the automatic in-
tervention of the residual current device
easier. Protection earthing involves not
only the electrical system, but also all the
other systems and metallic parts of the
building, including piping, beams, hea-
ting system and so on, so that the whole
building turns out to be under safety con-
ditions, also in case a lightning should hit
the building.
Before proceeding with the opera-
tions, see "General safety info".
The appliance must be included in
an "Equipotential" system, which
efficiency must be tested, accord-
ing to the rules in force in the installation
country.
The electrician preparing the gen-
eral electrical system must guar-
antee a system in conformity with
the regulations, for what concerns the
direct and indirect contacts.
The electrician must connect all
the different earths to the same po-
tential, in order to achieve a good
"Equipotential" earthing system in the
area where the different appliances will
be installed.
For what concerns the connection
of the appliance to the room Equi-
potential system, use an electrical
yellow/green cable, suitable to the pow-
er of the devices installed.
The appliance plate "Equipotential" is
usually on its panel, near the system
used for the connection; carry out the
connection after having recognized the
same plate (see schematic drawing for
the correct location).
