Electrostatic Discharge

A discharge of static electricity from a finger or other conductor may damage system boards or other
static-sensitive devices. This type of damage may reduce the life expectancy of the device.

Preventing Electrostatic Damage

To prevent electrostatic damage, observe the following precautions:

●

Avoid hand contact by transporting and storing products in static-safe containers.

●

Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations.

●

Place parts on a grounded surface before removing them from their containers.

●

Avoid touching pins, leads, or circuitry.

●

Always be properly grounded when touching a static-sensitive component or assembly.

Grounding Methods

There are several methods for grounding. Use one or more of the following methods when handling or
installing electrostatic-sensitive parts:

●

Use a wrist strap connected by a ground cord to a grounded workstation or computer chassis. Wrist
straps are flexible straps with a minimum of 1 megohm +/- 10 percent resistance in the ground
cords. To provide proper ground, wear the strap snug against the skin.

●

Use heelstraps, toestraps, or bootstraps at standing workstations. Wear the straps on both feet
when standing on conductive floors or dissipating floor mats.

●

Use conductive field service tools.

●

Use a portable field service kit with a folding static-dissipating work mat.

If you do not have any of the suggested equipment for proper grounding, contact an HP authorized
dealer, reseller, or service provider.

NOTE:

For more information on static electricity, contact an HP authorized dealer, reseller, or service

provider.
