EARTHING / It is essential to
earth the unit.To this purpose, it
is necessary to connect to an ef-
ficient earthing system the ter-
minals marked with the symbols pla-
ced on the line-receiving terminal box.
The earthing system should comply
with the local law in force.
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 responsibi-
lity for the non-compliance with these
safety regulations.It is necessary to
verify this fundamental safety requisite
and, in case of doubt, ask for an accu-
rate testing of the system by professio-
nally qualifi ed personnel.The Manu-
facturer cannot be deemed responsible
for any damages caused by the lack of
unit earthing.
Never interrupt the earth wire
(Yellow-Green).

If necessary, remove the terminal
box protection panel located on the
back of the machine.
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 ear-
thing involves not only the electrical
system, but also all the other systems
and metallic parts of the building, in-
cluding piping, beams, heating system
and so on, so that the whole building
turns out to be under safety condi-
tions, 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,
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.
