• Each device has a unique serial number for commissioning support.
It is also located on the removable barcode label: See the ABT online help for
the associated workflow.
• Each device has a unique MAC address.
• Each device with KNX PL-Link has a unique KNX ID.
• Cable length, topology, etc.: See installation manual Desigo TRA, CM111043.
• The cable insulation must always comply with the present rated voltage.
• When the supply voltage of the room automation station is transited to external
devices, the cable cross section must always correspond to the rated current
of the safety circuit breaking device.
Observe local regulations in any case.
The room automation stations can be snapped onto a standard mounting rail.
The automation station has pluggable screw terminal blocks to connect the AC 24
V supply, the AC 24 V outlets, the KNX PL-Link, and the DALI bus.
The TX-I/O modules are snapped onto the mounting rail on the right side of the
room automation station. The island bus is created automatically in this process.

*) 50 °C / 122 °F is admissible if the bus supplies use max. 2/3 of the specified
load: KNX PL-Link 105mA, DALI 85mA and island bus 400mA.
PXC3.E16A-100A: 50 °C / 122 °F is admissible without restrictions.
You must ensure, however, that sufficient ventilation is available to maintain
the permissible ambient temperature for the devices (inside the cabinet /
installation box).
Outside, the temperature must be 10 K lower.
See installation manual Desigo TRA, CM111043.
Island bus Polarity: If a TXS1.12F10 supply module is connected to output
24 V, do not invert ~ and ⊥.
The devices are not damaged but island bus communications will not work.
AC 24 V operating voltage is incorrectly wired (conductors ~ and ⏊ inverted).
If island bus or USB communications do not work, this is an indicator that the
