3.1 WARNINGS FOR KNX/EIB INSTALLATIONS
1. The length of the bus line between the 4 channel 16 A Easy push-button
panel and the power supply unit must not exceed 350 metres.
2. The length of the bus line between the 4 channel 16 A Easy push-button
panel 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 E).
5. Do not damage the electrical continuity conductor of the shielding (figure F).
3.2 ELECTRICAL CONNECTIONS
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 G ).
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 F ).
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 sepa-
rated by at least 4 mm (figure H ).
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.
WARNING: the unused bus signal cables and the electri-
cal continuity conductor must never touch elements un-
der power or the earth conductor!
