Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It
occurs when electronic components are improperly handled and can result in complete or
intermittent failures.
Always follow ESD-prevention procedures when removing and replacing components.
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 yourself by touching the metal part of the
chassis.
