Installation and commissioning
Rain Sensor KNX R
• Date of issue: 05.11.2010 • Technical changes reserved. Errors reserved.
2.3.3. Preparing the sensor
The sensor cover snaps in on the left and right along the bottom edge (see Fig.). Re-
move the cover. Proceed carefully, so as not to pull off the wire connecting the PCB in
the bottom part with the rain sensor in the cover (soldered cable connection in case of
230 V AC version, cable with plug in case of 24 V DC version).
Push the bus connection cable through the rubber seal on the bottom of the sensor and
connect bus +/- to the provided clamps.
For 24V devices the connection cable must be plugged in between the cover and circuit
board.
