Warning
Carry out the electrical connections after having completed all the hydraulic connections.
ELECTRICAL CONNECTIONS
The HYBRID MODULE, the boiler, and the external unit must be supplied separately, accordingly to the national and local normatives in force.
You must make a RS485 type connection between the HYBRID MODULE and the external unit. This connection can be made using a shielded
cable with a small cross-section (0.25 mm
2
cross-section recommended). Make sure that the cable is not positioned in the vicinity of a power
connection.
Electric circuit
• Check that the mains power supply voltage and frequency are in line with the data indicated on the system data plate (“Technical Data” table).
• For greater safety, ask a qualifi ed technician 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 differential 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 authorised 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 product 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 between 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 installation.
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 improper grounding or electrical system anomalies.
• Connect the power supply cable to a 230V - 50Hz network, checking for LN polarity 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 lightning. In the event that you need to change the fuses, using fast-acting fuses.
Warning: Prior to accessing the terminals, all the supply circuits must be disconnected.

The HYBRID MODULE and the external unit electric power supplies must be connected respectively to a circuit breaker (RCCB) with a minimum
threshold of 30mA.
Note: For information on the boiler electrical connection consult the relevant manual.
