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 label attached on the ap-
pliance. Any other connection is to
be considered improper and therefo-
re dangerous.
It is mandatory to respect the
connection provided by the
manufacturer, visible on the
connection label near the terminal
board.
It is forbidden to modify the
wiring inside the equipment
ELECTRICAL CONNECTION
THE CABLE TO THE TERMINAL
BOARD / Connect the power cable
to the terminal board as described in:
"Power supply connection" and indica-
ted on the connection plate.
The diagram and the table (see Tech-
nical data) indicate the possible con-
nections according to the mains voltage.

TENTIAL" SYSTEM - see SECT. IMAGES - REF. e) / The protecti-
ve earthing consists of a series of
contrivances, which ensure the same
earth potential in the electrical ear-
ths, 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 intervention
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,
heating system and so on, so that the

whole building turns out to be under
safety conditions, also in case a light-
ning 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,
according to the rules in force in the
installation country.
The electrician preparing the
general electrical system must
guarantee a system in conform-
ity with the regulations, for what con-
cerns the direct and indirect contacts.
The electrician must connect all
the different earths to the same
potential, in order to achieve a
good "Equipotential" earthing system in
the area where the different appliances
will be installed.
For what concerns the connec-
tion of the appliance to the room
Equipotential system, use an
electrical yellow/green cable, suitable
to the power 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 recogni-
zed the same plate (see schematic
drawing for the correct location).
Connect an edge of the earth electric
cable (the cable must be characteri-
zed by the double colour yellow/gre-
en) to the system used for the applian-
ce "Equipotential" connection (see
schematic drawing Fig. 1).
Connect the opposite edge of the
earth electrical cable to the system
used for the "Equipotential" con-
nection of the area where the ap-
pliance will be installed (Fig. 2).
