3. Installation
To prevent equipment damage, install an air terminal so that the tip
is as high above the instruments and sensors as possible.
CAUTION!
To prevent corrosion and oxidation, use copper paste or equivalent on screws and
connector threads.
3.1 Selecting location
Finding a suitable site for the product is important for getting representative ambient
measurements. Make sure that the site represents the general area of interest.
Allow sufficient clearance for the wind sensors. Do not install wind sensors next to
a building or any other object that can affect the flow of air.
Installations on top of high buildings or masts and in sites on open
grounds are vulnerable to lightning strikes. A nearby lightning strike may induce
a high-voltage surge not tolerable by the internal surge suppressors of the
instrument. Additional protection is needed in regions with frequent, severe
thunderstorms, especially when long line cables (>30 m (98 ft)) are used.
Vaisala recommends using a surge protector, such as WSP150, in all sites with an
elevated risk of a lightning strike.
CAUTION!
