Electrical Connections

ATTENTION
The electrical connections shall be
made after completing all hydraulic
connections.
The internal and external units must be
powered separately according to what
is indicated on the tables. Between the
internal and external units should also
be made a MOD BUS connection. This
connection may be made through the
use of a cable of reduced section (re-
commended section 0,75 mm
not let this cable walk along a power
connection.

Electrical circuit

Check that the voltage and frequency
of power supply from the network coin-
cide with the data shown in the data
plate of the appliance (see table «Tech-
nical Data»)

In order to ensure greater security,
the main electrical system should be
checked by a qualifi ed technician be-
fore proceeding with the installation
(see note).
The manufacturer is not liable for any
damage caused by installation with im-
proper grounding or abnormalities in
the electrical system.
Check that the installation is adequate
to support the power consumption of
the installed units, indicated on the data
plate of the product.
2 ). Do
The electrical connections must be car-
ried out with the aid of a fi xed supply
connection (do not use mobile sockets)
and equipped with a bipolar switch, ha-
ving a distance between the contacts of
at least 3 mm.
It is essential to connect the appliance
to a correctly grounded electrical cir-
cuit, as to ensure the safety of the ins-
tallation.

Connect the power cord to a 230V-50Hz
or (400V-50Hz), verifying the polariza-
tions of the L-N (or L1, L2, L3, N) connec-
tion and the connection to the earth.
The section of the used cables must
comply with the power of the installa-
tion (see plate characteristic). For the
electrical connection of the installation,
you shall not use power strips, extension
cords and adapters. It is also prohibited
to use the hydraulic pipes and heating
system pipes to ground the installation.
The system is not protected against
lightning. If you need to change the
fuses, use fast fuses.
Warning: Before obtaining access to
terminals, all supply circuits must
be disconnected.
