RETROFIT INSTALLATION 
This chapter describes the retrofit installation procedure for WMT700. 
Retrofit Installation Procedure 
At the measurement site, WMT700 needs to be mounted and connected 
to the power source and data acquisition system. 
After upgrading to WMT700, it is possible to install the optional bird 
prevention kit available for the wind sensor. For more information, see

 Ultrasonic Wind Sensor Series WMT700 User's 
Guide. 
WARNING 
To protect personnel (and the wind sensor), a lightning rod must be 
installed with the tip at least one meter above WMT700. The rod must be 
properly grounded, compliant with all local applicable safety regulations. 
Do not install the wind sensor above the top of the lightning protection 
rod. 
WARNING 
Do not install WMT700 when there is a risk of thunderstorm or lightning 
activity in the area. 
CAUTION 
When handling WMT700, do not rotate, pull, strike, bend, scrape or 
touch the transducers with sharp objects. Any impact on the wind sensor 
array damages the device.
