RF/TP media coupler/repeater
(7) Repeater
(8) Power supply
4 Operation as media coupler
The physical address of the media coupler is the address of a line or a backbone coupler x.y.0
and must match the logical topology of the KNX system. Observe the instructions in the tech-
nical documentation regarding the address.
Power is supplied via the KNX bus cable.
With operation as a media coupler, the repeater function can also be activated.
5 Operation as repeater
The physical address of the radio repeater is the address of a normal KNX participant x.y.z
(z≠0) within the address range of the KNX radio system. Observe the instructions in the tech-
nical documentation regarding the address.
Power is supplied via a separate power supply (accessory) or via the connection to a KNX line.
Do not use the 30 V output of a KNX power supply. The media coupler may heat up to an
impermissible temperature.
Repeater mode is active after the physical address is assigned. Once this happens, pro-
gramming via bus line is blocked. Then the device can only be reached by radio. To ad-
dress the device via the bus line, reset the device to default settings.
6 Information for electrically skilled persons
DANGER!
