4.2 Anti-static Precautions

WARNING:

Failure to take ESD precautions during the maintenance of the

ACT-457A may result in permanent damage to the ACT-457A and

severe injury to the user.

Electrostatic discharge (ESD) can cause serious damage to electronic components,

including the ACT-457A. Dry climates are especially susceptible to ESD. It is therefore

critical that whenever the ACT-457A is accessed internally, 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 ACT-457A, place it on an

antic-static pad. This reduces the possibility of ESD damaging the ACT-457A.

 Only handle the edges of the PCB: When handling the PCB, hold the PCB

by the edges.
