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 heel straps, toe straps, or boot straps 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, have an HP-authorized
reseller install the part.
NOTE:
For more information on static electricity or assistance with product installation, contact
your HP-authorized reseller.
