ATTENTION: the device must only be installed by qualified personnel,
observing the current regulations and guidelines for KNX installations.
Recommendations for installing the KNX
1. The length of the bus line between the push-button panel and the power supply must
not exceed 350 metres.
2. The length of the bus line between the push-button panel and the furthest away KNX
device to control 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 electricity line (figure D).
5. Do not damage the electrical continuity conductor of the shielding (figure E).
ATTENTION: The bus signal cables that are not used and the electrical
continuity conductor must never touch any live elements
or the earthing conductor!
Figure B shows a diagram of the electrical connections.
1. Connect the red wire of the bus cable to the red terminal (+) of the terminal and the
black wire to the black terminal (-). Up to 4 bus lines can be connected to the bus
terminal (same coloured wires on the same terminal) (figure F ).
2. Insulate the shield, the electrical continuity conductor and the other white and yellow
wires of the bus cable (if a 4 conductor bus cable is being used), that are not necessary
(figure E ).
3. Insert the bus terminal in the device's pins. The correct insertion direction is
determined by the fixing guides. Insulate the bus terminal with the cover to be screwed
onto the device. The cover guarantees the minimum separation distance of 4 mm
between the power cables and the bus cables (figure G ).
