WARNING: the installation of the device must be exclusively done by
qualified personnel, following the regulations in force and the
guidelines for KNX/EIB installations.
Warnings for KNX/EIB installations
1. The length of the bus line between the IR movement detector and the power supply
unit must not exceed 350 metres.
2. The length of the bus line between the IR movement detector and the most distant
KNX/EIB device must not exceed 700 metres.
3. If possible do not create ring circuits so as to prevent undesirable signals and
overloads.
4. Keep a distance of at least 4 mm between the individually insulated cables of the bus
line and those of the electric line (figure C).
5. Do not damage the electrical continuity conductor of the shielding (figure D).
WARNING: the unused bus signal cables and the electrical continuity
conductor must never touch elements under power or the earth
conductor!
In order to function correctly, the detector must be installed at a distance from sources
of heat, such as radiators, and must not be positioned in direct sunlight.
Figure B shows the electrical connections diagram.
1. Connect the bus cable's red wire to the terminal's red connector (+) and the black wire
to the black connector (-). Up to 4 bus lines can be connected to the bus terminal
(wires of the same colour in the same terminal) (figure E).
2. Insulate the screen, the electrical continuity conductor and the remaining white and
yellow wires of the bus cable (should a bus cable with 4 conductors be used), which
are not needed (figure D).
3. Insert the bus connector into the special feet of the device. The fastener guides
determine the direction it should be inserted. Insulate the bus terminal using the
relative cover, which must be screwed onto the device.
The cover guarantees that the power cables and the bus cables are separated by at
least 4 mm (figure F).
