IMPORTANT
The following is mandatory:
• The use of an all-pole thermal-magnetic circuit breaker, line disconnecting switch, with contact gap of at least 3 mm, compliant with EN
standards.
• Respect the L (Line) - N (Neutral) connection.
• Use cables of section 1.5 mm2 or thicker, complete with cable lugs.
• Leave the ground wires at least 2 cm longer than the L (Line) - N (Neutral) wires.
• Refer to the wiring diagrams of this manual for any intervention of an electrical nature.
• Make the connections to an efficient grounding system (*).
• DO NOT use the water pipes for grounding the unit.
(*) The manufacturer declines any liability in case of damage caused by failure to ground the unit and non-compliance with the

7.2.2 Notes regarding electrical connections
The FG7 OR 3G1.5 panel power supply cable is already connected to the terminal block.
In case of replacement, use an appropriate cable in accordance with the applicable regulations.
The burner power supply is taken directly from the terminal block in case of single-phase type and with maximum current absorption of 3A.
The system water circulating pump supply is taken directly from the terminal block in case of single-phase type and with maximum current
absorption of 3A.
In case of burner or circulating pump absorption higher than that foreseen, or a three-phase supply, the power relays interfaced with the
outputs in the terminal block must be used. Remote ignition consent offers the possibility of lighting the boiler remotely. It must be jumpered
if not used.
The external boiler safety consent allows the insertion of a further contact that causes the burner to shut down safely (the burner's power
supply is cut off). It must be jumpered if not used.
The contact for the room thermostat only acts on the water circulating pump.
It must be jumpered if not used.
