manufacturer, visible on the
connection label near the terminal

The protective earthing consists of a
series of contrivances, which ensure
the same earth potential in the electri-
cal earths, thus preventing the same
earths from being tensioned.
The earthing has the aim to ensure
that the earths of the household ap-
pliances 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-

Before proceeding with the ope-

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 appli-
ances 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 characte-
rized by the double colour yellow/
green) to the system used for the
appliance "Equipotential" connection
(see schematic drawing Fig. 1).
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
installed (Fig. 2).
