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.

GENERAL WARNINGS

Operators have a duty to fami-
liarise themselves adequately,
using this manual before per-
forming any intervention, adopting
the specific safety requirements to
make every kind of human-compu-
ter interaction safe.

OPERATIONS FOR COMMISSIONING

- 12 -
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).
Any technical modification that
affects the operation or safety
of the machine must only be
carried out by the technical person-
nel of the manufacturer or by techni-
cians that are formally authorised by
the manufacturer. Failure to do so
exempts the manufacturer from any
liability for for any possible resulting
modifications or damage.
