Preventing Electrostatic Discharge Damage

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. Ensure that

the chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap, ensuring

that it makes good 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 available, ground
