CONNECTION TO ENERGY SOURCES
4.3 CONNECTION THE
"EQUIPOTENTIAL" SYSTEM
The protective earthing consists of a series of measures de-
signed to ensure the electrical masses the same earth poten-
tial avoiding a situation where these may be in tension. The
purpose of earthing is therefore to ensure that the masses of
the appliances are at the same earth potential.
Earthing also facilitates
intervention.
The protection earthing does not only concern the electrical
system but all the other systems and metal parts of the build-
ing, from the pipes to the plumbing system, from the beams
to the heating system and so on, such that the entire building
is secured, also in relation to a possible lightning strike that
could affect the building.
Obligation to exclude the power supply upstream
of the appliance whenever it is necessary to oper-
ate safely.
The appliance must be included in an "Equipoten-
tial" system whose efficiency must be verified in
accordance with the rules in force in the country
of installation.
The electrician that prepares the general electri-
cal system must ensure the structure is compliant
in relation to direct and indirect contacts.
The electrician must connect all the different
masses to the same potential to provide a good
"Equipotential" earthing system within the place
where the appliance is installed.
For connection of the appliance to the "Equipo-
tential" system of the premises, a yellow/green
power cord is required that is appropriate to the
power of the installed devices.
The "Equipotential" plate of the appliance is typically located
on the panel of the appliance, in the vicinity of the system used
for attachment. Once identified (see schematic digram for the
correct location), proceed with the connection.
• Connect one end of the electric earthing cable (the cable
should be marked with double yellow/green) to the system
used for the "Equipotential" connection of the appliance
(see schematic diagram Fig. 6).
• Connect the opposite end of the electric earthing cable to
the system used for the "Equipotential" connection of the
place where the appliance is installed Fig. 7).
