Safety information

vWear a grounded wrist strap against your skin to eliminate static on your body.

vPrevent the part from touching your clothing. Most clothing is insulative and retains a charge even when you are wearing a wrist strap.

vUse the black side of a grounded work mat to provide a static-free work surface. The mat is especially useful when handling ESD-sensitive devices.

vSelect a grounding system, such as those listed below, to provide protection that meets the specific service requirement.

Note

The use of a grounding system is desirable but not required to protect against ESD damage.

–Attach the ESD ground clip to any frame ground, ground braid, or green-wire ground.

–Use an ESD common ground or reference point when working on a double-insulated or battery-operated system. You can use coax or connector-outside shells on these systems.

–Use the round ground-prong of the AC plug on AC-operated computers.

Grounding requirements

Electrical grounding of the computer is required for operator safety and correct system function. Proper grounding of the electrical outlet can be verified by a certified electrician.
