Product Related Safety
Precautions
WAT12 Analog Wind Transmitter 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 the grounding of the
outdoor installation 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

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
User's Guide ________________________________________________________

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.
- Always hold the boards by the edges and avoid touching
the component contacts.
