Safety
The product 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.
WARNING
To avoid electric shock, never open the PTB330 enclosure while the
transmitter is connected to mains power.
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.
- Always hold the boards by the edges and avoid touching the
component contacts.
