3.1 Anti-static Precautions

WARNING:

Failure to take ESD precautions during the installation of the A300 may result in permanent damage to the A300 and severe injury to the user.

Electrostatic discharge (ESD) can cause serious damage to electronic components, including the A300. Dry climates are especially susceptible to ESD. It is therefore critical that whenever the A300, or any other electrical component is handled, the following anti-static precautions are strictly adhered to.

 Wear an anti-static wristband: - Wearing a simple anti-static wristband can

help to prevent ESD from damaging the board.

 Self-grounding:- Before handling the board touch any grounded conducting

material. During the time the board is handled, frequently touch any conducting materials that are connected to the ground.

 Use an anti-static pad: When configuring the A300, place it on an antic-st atic

pad. This reduces the possibility of ESD damaging the A300.

 Only handle the edges of the PCB:-: When handling the PCB, hold the PCB

by the edges.
