ELECTRICAL CONNECTION OF THE
CABLE TO THE TERMINAL BOARD /
Connect the supply cable to the termi-
nal board as described in: "Connection
to the electrical power supply". The
diagram and the table (see Technical
data) indicate the possible connections
according to the mains voltage.

TIAL" SYSTEM - see SECT. IMA-

The protective earthing 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 ma-
kes the automatic intervention of the re-
sidual current device easier. Protection
earthing involves not only the electrical
system, but also all the other systems
and metallic parts of the building, inclu-
ding piping, beams, heating system and
so on, so that the whole building turns
out to be under safety conditions, 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 ef-

ficiency must be tested, according 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).
1. Connect an edge of the earth electric
cable (the cable must be characterized
by the double colour yellow/green) to
the system used for the appliance "Equi-
potential" connection (see schematic
drawing Fig. 1).
2. Connect the opposite edge of the ear-
th electrical cable to the system used
for the "Equipotential" connection of the
area where the appliance will be instal-
led (Fig. 2).
