ELECTRICAL CONNECTIONS
4.1 PRELIMINARY CHECKS
The electrical connection of the various devices present on
the automation (photocells, digital keypads, transponder card
readers, etc.) to the control unit must be made through the
Nice
“Bluebus” system. For the other connections, refer to that
specified below.
f
All electrical connections must be made with the
system disconnected from the mains electricity and
with the back-up battery (if present) disconnected.
a
The connection operations must only be carried out
by qualified personnel.
f
Mount a device on the electric power line that
completely disconnects the automation from the
grid.
–
The disconnection device must have contacts with a
sufficient gap to ensure complete disconnection, under
the Category III overvoltage conditions, in accordance
with the installation instructions. If necessary, this
device guarantees quick and safe disconnection from
the mains power and therefore must be positioned
in sight of the automation. If located in a concealed
position, it must be equipped with a system that
prevents inadvertent or unauthorised reconnection of
power, to avoid potential hazards.
