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 KNX device
to be controlled must not exceed 700 metres.
3. To avoid unwanted signals and overvoltages, do not use ring circuits.
4. Keep a distance of at least 4mm 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 clamp (+) of the terminal, and the
black wire to the black clamp (-). 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 clamp in the pins of the device. 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
4mm between the power cables and the BUS cables (figure G ).
4. Connect the load to the relevant screw terminals on the back of the actuator (figure A ),
making sure the current limits specified in the Technical Data are not exceeded.
