Mounting and electrical connection
General
Mount in suitable flush-mounted or surface appliance boxes.
In outdoor installations: Use appliance box IP55.
Do not place the device in metallic small distribution boards or appliance
boxes.
Do not lead any wire or sheathed cables from other power circuits through the appli-
ance box.
Precondition: To ensure good transmission quality, keep a sufficient distance from
possible interference sources, e.g. metallic surfaces, microwave ovens, hi-fi and TV
sets, ballasts or transformers.
Connect the device and mount it for use as media/segment coupler
The device is connected to and supplied by a KNX bus cable (TP).
Precondition: Ideally, the media coupler is positioned in the centre of an RF installa-
tion (domain), to allow low-loss and thus interference-free communication with all the
associated RF devices.
￭
Connect device to a KNX bus cable. For this, use a KNX device connection
terminal. Ensure correct polarity.
If the media coupler is used as a line coupler, the KNX bus cable must be the
main line of a TP area. If the media coupler is used as a backbone coupler,
the KNX bus cable must be the TP area line (Backbone) of the KNX installa-
tion. If the media coupler is used as a segment coupler, the KNX bus cable
must be the first segment of the line.
￭
Place the device in the appliance box.
￭
When laying the antenna, extend the antenna extended as much as possible.
If this is not possible, position the antenna behind the device in a circular ar-
rangement.
When using blank covers, make sure the antenna does not lie directly behind
the metal supporting frame.
Connect the device and mount it for use as a repeater only (no media/segment
coupler function)
If needed, the repeater can be connected to a KNX bus cable (TP) via which it is sup-
plied, as long as the bus cable is the TP line of the associated media coupler. Thus
the use of the repeater is especially relevant for retroactive solutions in existing TP
systems.
Alternatively, a repeater can also be supplied via a separate DC voltage supply, even
without KNX bus voltage.
