Removal and Replacement Preliminaries
Maintenance and Service Guide
4–5
When using fixtures that must directly contact dissipative 
surfaces, only use fixtures made of static-safe materials.
Keep the work area free of nonconductive materials, such as 
ordinary plastic assembly aids and Styrofoam.
Handle electrostatic-sensitive components, parts, and 
assemblies by the case or PCM laminate. Handle these items 
only at static-free workstations.
Avoid contact with pins, leads, or circuitry.
Turn off power and input signals before inserting or 
removing connectors or test equipment.
4.7 Grounding Equipment and 
Methods
Grounding equipment must include either a wrist strap or a foot 
strap at a grounded workstation.
When seated, wear a wrist strap connected to a grounded 
system. Wrist straps are flexible straps with a minimum of 
one megohm ±10% resistance in the ground cords. To 
provide proper ground, wear a strap snugly against the skin 
at all times. On grounded mats with banana-plug connectors, 
connect a wrist strap with alligator clips.
When standing, use foot straps and a grounded floor mat. 
Foot straps (heel, toe, or boot straps) can be used at standing 
workstations and are compatible with most types of shoes 
or boots. On conductive floors or dissipative floor mats, use 
foot straps on both feet with a minimum of one megohm 
resistance between the operator and ground. To be effective, 
the conductive strips must be worn in contact with the skin.
