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 /- 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.
