12. 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.
ADI CD 70 to ADI CD 750: 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).
ADI CD 850 to ADI CD 950: The electric supply must be three-phase, 380 V, 50 Hz, ground connection, for the motor
fan.
Protect separately the three-phase motor's electric supply (L1-L2-L3) from the boiler's electric supply (Ph-N).
