Installation and connection
The KNX ENO 620 and 622 devices differ only in the housing; their functions are identical. KNX ENO 620 has a
particularly compact design. KNX ENO 622 is suitable for mounting on a recessed wall box or on material with poor
radio penetration properties (e.g. metal or concrete).
The unit can be on-wall mounted (e.g. on masonry or wood). Select an installation location that lies within the range
of the EnOcean sensors being used with the device. Avoid shielding objects (metal cabinets, etc.) and sources of
interference (computers, electronic transformers, ballasts, etc.) near the gateway.
Detailed information on coverage planning and HF penetration can be found in the sensor data sheets and at
.

The device is connected to the EIB/KNX bus through a bus terminal. Ensure that the polarity of the terminal is as
shown on the device. The device is powered via the bus.
Initial state
A new gateway has a physical address of 15.15.255. There are no preset group addresses and connections to
EnOcean devices.

To program the physical address (EIB/KNX) on the ETS press the programming key (“Learn Key KNX”). The red LED
lights up when the learn mode is active ("Learn LED KNX"). It goes out when the device receives the physical
address. The group addresses and parameter settings can then be programmed on the ETS.
