Safety instructions for installation
è
ATTENTION! The installation, the connection to the 230V/50 Hz network and
the maintenance of the Supply control unit Supply control unit will only be
carried out by authorized personnel!
è
The installation of the Supply control unit is recommended to be made within
an electrical panel.
è
ATTENTION! DO NOT UNFASTEN THE FRONT LID! DANGER OF
ELECTRIC SHOCK!
Only the protection lids of the connections can be unfastened.
è
ATTENTION! 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 terminals of the Supply control
unit will be made through two isolated (Cu) wires, with a section of 0,75mm².
è
ATTENTION! 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).
è
The connection of the (Cu) 0,75mm² grounding wire between the grounding
terminal of the electrical panel and the grounding terminal of the Supply
control unit is MANDATORY.
è
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.
è
IMPORTANT! Install the protection lids of the Supply control unit's
connections before connecting the 2 supply fuses (230V/50Hz).
è
PAY ATTENTION to the polarity of the terminals when connecting them to
the Supply control unit of a buffer accumulator (max. 7 Ah). The inversion of
the terminals leads to the failure of the accumulator. The installation and
connection of the accumulator will be carried out by authorized personnel.
è
DO NOT TOUCH the wires exiting from the connectors and the terminals of
the control supply unit. Disconnect the fuses (10 A) from the supply's phase
and null of the Supply control unit.
è
ATTENTION! Do not supply components of the installation separately
(Outdoor panel, connection boxes, Terminals etc.) at tensions higher than 15V
DC or directly from the network (230V/50Hz). DANGER OF ELECTRIC
SHOCK and of the door phone system's destruction.
