Safety Precaution - Electricity
Follow these simple precautions to protect yourself from harm and the products from
damage.
1. To avoid electrical shock, always disconnect the power from your PC chassis
before you work on it.
2. For the sake of the equipment, disconnect power before making any configura-
tion changes. The sudden rush of power as you connect a jumper or install a
card may damage sensitive electronic components.
3. Electronic components are also vulnerable to damage by electrostatic dis-
charge. An electrostatic charge can build up on the human body, especially
where the air is dry. At minimum, dissipate potential body charge before han-
dling any electronic board by touching a conductive surface on the chassis.
Only then remove circuit boards from their antistatic bags. Handle boards by the
edges or mounting brackets only; do not touch components or connecting pins.
