Safety
Vaisala WINDCAP
®
Ultrasonic Wind Sensor WMT701, WMT702, or
WMT703 delivered to you has been tested for safety and approved as
shipped from the factory. Note the following precautions:
WARNING
Make sure that you connect only de-energized wires.
WARNING
Using a long cable between different units (sensors, transmitters, power
supplies, and displays) can cause a lethal surge voltage, if a lightning
strike occurs in the vicinity. Always apply proper grounding procedures
and follow the requirements of the local Electrical Code.
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.
