4.4 CONNECTION TO
"EQUIPOTENTIAL" SYSTEM
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 house-
hold 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 lightning should hit the building.
Obligation to interrupt the electrical input up-
stream the appliance each time it's necessary to
operate in safety conditions.
The appliance must be included in an "Equipo-
tential" 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 conformity
with the regulations, for what concerns 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 connection of the appli-
ance to the room Equipotential 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 draw-
ing for the correct location).
• 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 "Equipotential" con-
nection (see schematic drawing Fig. 10).
• Connect the opposite edge of the earth electrical cable to
the system used for the "Equipotential" connection of the
area where the appliance will be installed (Fig. 11).
