Lenovo IdeaCentre AIO340-22IWL (F0EB009TRK) [10/57] Grounding requirements

1. Use product-specific ESD procedures when they exceed the requirements noted here.

2. Make sure that the ESD protective devices you use have been certified (ISO 9000) as fully effective.

When handling ESD-sensitive parts:

• Keep the parts in protective packages until they are inserted into the product.

• Avoid contact with other people while handling the part.

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

• Prevent the part from touching your clothing. Most clothing is insulative and retains a charge even when

you are wearing a wrist strap.

• Use 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.

• Select 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.
