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.
