4 Connection

Disconnect power of the KNX bus. Connect the interface to the KNX TP-1 (EIB) bus using the
KNX standard connector (red/grey) of the interface, respect polarity and then reconnect power
of the KNX bus.

Then it will start an initialization process, KNX/EnOcean Gateway will be printed on the ABB
device display for a few seconds (see the location of the display in
operation starts when display turns OFF.
It is important to bear in mind that changes made during the initialization process will not have
effect until it finishes.
EnOcean protocol runs in a wireless mode, so no wiring is needed during the connection stage.
To connect EnOcean devices with the KNX/EnOcean Gateway EnOcean interface, please
follow instructions in this manual and recommendation below.

4.2.1 Placement

The ABB interface antenna has a better sensibility when the device is placed vertically, and
therefore this is the preferred position when placed (antenna zone should be located in the
bottom side, floor side, once the device is fixed to the wall).
The coverage distance (see Table 4.1) of the signal emitted by the ABB, or by any other
EnOcean device, is determined by the room geometry and where they are placed. As an
example, long narrow corridors with wide walls are an adverse situation. People or other
obstacles can reduce the coverage distance too. Therefore, is advised to always think in the
worst possible scenario to decide the placement of the device to ensure a good stability in the
radio system.

Conditions
Under ideal conditions: broad room, no obstacles, good antenna design and
good antenna positions.
The room is filled with furniture and people and penetration through up to 5 dry
walls or up to 2 brick walls or up to 2 aero concrete walls.
Identical to the previous case but the receiver is placed to a room corner or
range along a narrow floor.
Metal-reinforced ceilings at upright penetration angle (in strong dependence of
reinforcement density and antenna positions).
