Installation and commissioning
Mounting can be recessed in the wall and thus almost "invisible", because the housing has the right
size for mounting in a standard flush-mounted box.
When selecting the mounting location, the range of the radio devices to be connected to the device
must be taken into account. Shielding objects (e.g. metal cabinets) or interfering transmitters (e.g.
computers, electronic transformers, ballasts) near the gateway should be avoided.
The device is connected to the KNX bus by means of a bus terminal. The correct polarity of the
terminal as printed on the device must be observed.
The KNX RF/TP Coupler 673 secure has the following controls and displays:
The device is only supplied via the KNX bus.
