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.
