Product Related Safety
Precautions
The WAA151 Anemometer delivered to you has been tested
for safety and approved as shipped from the factory. Note
the following precautions:
WARNING Ground the product, and verify outdoor installation
grounding periodically to minimize shock hazard.
CAUTION Do not modify the unit. Improper modification can damage
the product or lead to malfunction.
ESD Protection
Electrostatic Discharge (ESD) can cause immediate or latent
damage to electronic circuits. Vaisala products are
adequately protected against ESD for their intended use.
However, it is possible to damage the product by delivering
electrostatic discharges when touching, removing, or
inserting any objects inside the equipment housing.
To make sure you are not delivering high static voltages
yourself:
- Handle ESD sensitive components on a properly
grounded and protected ESD workbench. When this is
not possible, ground yourself to the equipment chassis
before touching the boards. Ground yourself with a wrist
strap and a resistive connection cord. When neither of the
above is possible, touch a conductive part of the
equipment chassis with your other hand before touching
the boards.
