2.4. Assembly of the sensor
First of all fit the windproof socket with connection. Also seal inlet pipes to avoid
infiltration.
Screw the base plate onto the socket and position the frame of the switching
programme. Connect the CO
terminals provided on the board.
Pin the sensor with the notches on to the metal frame, so that sensor and frame are
fixed.

2.5. Notes on mounting and commissioning

Never expose the device to water (e.g. rain) or dust. This can damage the electronics.
You must not exceed a relative humidity of 95%. Avoid condensation.
After the bus voltage has been applied, the device will enter an initialisation phase
lasting a few seconds. During this phase no information can be received via the bus.
