As a rule, the greatest potential for electrostatic damage occurs in areas with the
lowest relative humidity. But, because such damage can occur anywhere, all
personnel handling circuit packs should take the following precautions:
1. Since materials such as food wrappers, plastics, and Styrofoam
containers tend to generate static electricity, keep them away from all
circuit packs.
2. Be sure to read all warning labels on bags and cartons before opening
any packaging.
3. If possible, open all circuit packs at a static-safe work position using
properly grounded wrist straps and table mats that can dissipate static
electricity.
4. Whenever possible, wait to remove circuit packs from their protective
antistatic packaging until it is time to insert them into a bay.
5. Never touch a circuit pack's components, conductors, or connector pins.
Handle all circuit packs only by the faceplate or latch or by the top and
bottom outermost edges.
6. When opening and handling circuit packs or when working on backplanes,
always wear a grounded wrist strap or wear a heel strap and stand on a
grounded floor mat that can dissipate static electricity.
7. Always store and transport circuit packs in static-safe packages.
(Shielding is not required unless specified.)
8. Whenever you remove circuit packs from a shelf, immediately put them
into static-safe packages.
9. Try to keep relative humidity above 20 percent.
10. DDM-2000 shelves are equipped with grounding jacks for connecting
static ground wrist straps. The jacks are located on the bottoms of the
user panels.
