Grounding Methods to Prevent Electrostatic Damage  

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 tightly 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 
authorized reseller install the part. 

For more information on static electricity, or assistance with product installation, 
contact your authorized reseller.
