provided terminals while taking polarity into account
(see fig. 1).
Fastening the weather station:
Close the enclosure by putting the lid over the lower
part. The lid must snap into place on the left and the
right with a clear "click". Check that the lid and lower part
are properly snapped into place! Fig. 10 shows the cor-
rectly closed weather station from below.

Now slide the enclosure into the mounted holder from
above. The pegs of the holder must slot into the rails of
the enclosure (see fig. 11).
Figure 11
When needed, the weather station can be pulled out of
the holder in an upwards direction.
Notes:
Do not open the weather station if water (rain) can get
into the inside. A few drops are enough to damage the
electronics.
Take care that the connections are correctly made. A
wrong connection can destroy the electronics of the
weather station.
During assembly care should be taken that the tempera-
ture sensor (small circuit board on the lower part of the
enclosure) is not damaged. The cable connection be-
tween the circuit board and the rain sensor may not be
torn off or bent while making the connection.
The wind measurement value is first transmitted 30
seconds after initiating the supply voltage.

Maintenance
The weather station should be regularly (twice per year)
checked for soiling and cleaned if necessary. In case of
strong pollution, the wind sensor may cease to function,
rain may be reported permanently or no more sun may
be detected.
During maintenance and cleaning, the weather station
should always be separated from the bus and the supply
voltage for safety purposes.
