CHAPTER 3
INSTALLATION
This chapter provides you with information that is intended to help you
install this product.
Selecting Location
WS425 Ultrasonic Wind Sensor should be installed in a location that is
free from turbulence caused by nearby objects, such as trees or buildings.
Ideally, the sensor should be higher than any other object within the
horizontal radius of 300 m.
WARNING To protect personnel (and the wind sensor), a lightning rod must be
installed with the tip at least one meter above the wind sensor. The
rod must be properly grounded, compliant with all local applicable
safety regulations.
Installation Procedure
Unpacking Instructions
The ultrasonic wind sensor comes in a custom shipping container. The
sensor must be removed from the container carefully. It is important to
save the container and all the foam packing for future transporting or
shipping.
The sensor comes with a Hex-socket bolt and a grooved bolt to be used
in mounting.
CAUTION Never move the WS425 Ultrasonic Wind Sensor until it is in its custom
shipping container. Otherwise, the warranty will become void.
