Preventing Electrostatic Discharge Damage

When starting to install interface cards place the interface card on its shielded plastic bag if you lay it on your bench.

Electrostatic Discharge (ESD) can damage equipment and impair electrical circuitry. It occurs when electronic printed circuit cards are improperly handled and can result in complete or intermittent failures.

Always follow ESD prevention procedures when removing and replacing cards.

Wear an ESD-preventive wrist strap, ensuring that it makes good CAUTION skin contact. Connect the clip to an unpainted surface of the

chassis frame to safely channel unwanted ESD voltages to ground.

To properly guard against ESD damage and shocks, the wrist strap and cord must operate effectively. If no wrist strap is avail- able, ground yourself by touching the metal part of the chassis.

General observations

•Clean the case with a soft slightly moist anti-static cloth

•Place the unit on a flat surface and ensure free air circulation

•Avoid exposing the unit to direct sunlight and other heat sources

•Protect the unit from moisture, vapors, and corrosive liquids
