INSTALLATION
3.
3.1
1. The length of the bus line between the actuator and the power supply
unit must not exceed 350 metres.
2. The length of the bus line between the actuator and the most distant
KNX device must not exceed 700 metres.
3. To avoid unwanted signals and overvoltages do not use ring circuits.
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).
3.2
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 (wires of the
same colour in the same connector) can be connected to the 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
WARNING: the installation of the device must be exclu-
sively done by qualified personnel, following the regula-
tions in force and the guidelines for KNX installations.
WARNINGS FOR KNX INSTALLATIONS
WARNING: the unused bus signal cables and the electrical
continuity conductor must never touch elements under
power or the earth conductor!
ELECTRICAL CONNECTIONS
WARNING: cut off mains power before connecting the
device to the electricity mains!
