WARNING
Carry out the electrical connections after
having completed all the hydraulic con-
nections.
If Alteas or Genus range boilers are used,
the BUS decoupling board (supplied
with the product) must be installed, by
rigorously observing the instructions
contained in the kit. Failing to install the
board, or its faulty installation, will cause
the boiler to stop working and display
error 804. If this error appears, it is neces-
sary to shut off the power supply to the
boiler and check whether the board has
been installed correctly, in order to reset
the error and start the system.
The hybrid module, the boiler and the ex-
ternal unit must be powered separately in
conformity to the applicable national and
local regulations. Connect the BUS cable of
the hybrid module to the boiler’s BUS con-
nection using the orange connector sup-
plied. The hybrid module and the external
unit must be connected through a BUS con-
nection, to be made using a shielded cable
with reduced cross-sectional area (0.25 mm
2
recommended cross-sectional area). Make

sure that the cable is not positioned in the
vicinity of a power connection.
Electric circuit
• Check that the mains power supply volt-
age and frequency are in line with the
data indicated on the system data plate
(“Technical Data” table).
• For greater safety, ask a qualifi ed techni-
cian to perform a thorough check of the
electrical system.
• You are advised to check for the presence
of surge protection devices (SPDs) in the
power supply line, and the presence of
safety switches and diff erential circuit
breakers in the electrical panel output
that supplies the internal and external
units.
• The power supply connection is type
Y and replacing the connection cable
should only be performed by an author-
ised service centre, in order to avoid any
damages.
• Check that the installation is adequate to
support the power consumption of the
installed units, as indicated on the prod-
uct data plate.
• The electrical connections must made
with the help of a fi xed support (do not
use portable socket-outlets) and fi tted
with a bipolar switch, with a distance be-
tween contacts of at least 3 mm.
• It is essential that you connect the system
to an electrical system with grounding
which will ensure the safety of the instal-
lation.
It is also prohibited to use the hydraulic
and heating system connection pipes for
grounding of the system.
• The manufacturer is not liable for any
damage caused by a system with im-
proper grounding or electrical system
anomalies.
• Connect the power supply cable to a
230V - 50Hz network, checking for LN po-
larity compliance and grounding.
The cross-section of the cables used must
be in accordance with the system power
(see data plate).
The system is not protected against light-
ning. In the event that you need to change
the fuses, using fast-acting fuses.
Warning: Prior to accessing the termi-
nals, all the supply circuits must be dis-
connected.
