4 INSTALLATION
4.1 Recommended cables
Outdoor panel Supply control unit
UTP CAT5e (AWG24) cable for distances of maximum 70 m between the outdoor panel and
the supply control unit and 250m between the outdoor panel and the audio terminal.
For distances greater than 250 m, please request additional information from the producer.
Supply control unit
Flexible, multistrand cable, (Cu) 2 or 3 x 0,75 mm² for distances of maximum 50 m or
(Cu) 2 or 3 x 1 mm² for distances of maximum 100 m.
Supply control unit
Flexible, multistrand cable, (Cu) 3 x 0,75 mm²

AT TENTION! The installation, the connection to the 230V/50 Hz network and
the maintenance of the SCU supply control unit will only be carried out by
authorized personnel!
The installation of the supply control unit is recommended to be made within
an electrical panel.
AT TENTION! DO NOT UNFASTEN THE FRONT LID! DANGER OF
ELECTRIC SHOCK!
Only the protection lids of the connections can be unfastened.
AT TENTION! It is mandatory for the supply of the supply control unit from
the 230 V/50Hz network to be made through two automatic fuses of 10 A (on
phase and null). The connection of the F and N hubs of the supply control unit
will be made through two isolated (Cu) wires, with a section of 0,75mm².
AT TENTION! During the installation, connection of the supply control unit at
the 230 V/50Hz network and during service, the safety fuses from the panel
must be opened (POWER OFF).
The connection of the (Cu) 0,75mm² grounding wire between the grounding
hub of the electrical panel
unit is MANDATORY.
IMPORTANT! Before connecting the supply control unit's supply fuses, check
the precision of the connections in the system. Check both visually, and by
measurement with an ohmmeter.
IMPORTANT! Install the protection lids of the supply control unit's
connections before connecting the 2 supply fuses (230V/50Hz).
PAY AT TENTION to the polarity of the hubs when connecting them to the
supply control unit of a buffer accumulator (max. 7 Ah). The inversion of the
hubs leads to the failure of the accumulator. The installation and connection of
the accumulator will be carried out by authorized personnel.
DO NOT TOUCH the wires exiting from the connectors and the hubs of the
control supply unit. Disconnect the fuses (10 A) from the supply's phase and
null of the supply control unit.
AT TENTION! Do not supply components of the installation separately
(outdoor panel, connection boxes, terminals etc.) at tensions higher than
15Vd.c. or directly from the network (230V/50Hz). DANGER OF ELECTRIC
SHOCK and of the door phone system's destruction.
