ELECTRIC DRAWING
The electric installation must comply with the current rules. The electric power consumed by each boiler is
indicated in the table of technical characteristics.
NEO FIRE 80 to NEO FIRE 720: The electric supply must be 220/230 V, 50 Hz, single phase, ground connection.
(Remember: in case of 220/230 V, two phases, it is necessary to install an electric insulating transformer with
one of the phases of the secondary connected to ground acting as neutral).
NEO FIRE 810 to NEO FIRE 900: The electric supply must be three-phase, 380 V, 50 Hz, ground, for the motor
fan.
Protect separately the three-phase motor's electric supply (L1-L2-L3) from the boiler's electric supply (Ph-N).
