Electrostatic Discharge Damage Prevention and Warning
Workspace Setup
l Keep the work area free of non-conductive materials such as packaging material like
polyethylene bags, cardboard boxes, foam packing, and polystyrene foam peanuts.
Also keep the area clear of any non-essential insulators including newspapers,
magazines, radios, polystyrene cups, plastic lunch bags, regular tape, plastics, and so
forth. Immediately remove and discard these materials.
l Do not use brushes with synthetic bristles or acid brushes to clean the shelf, modules,
or pluggable transceivers.
l Use an electrostatic workbench, where available.
l Use a static-dissipative floor mat, if the floor is not conductive.
l Use a static-dissipative work mat, if the work surfaces is not conductive.
l Clean the ESD dissipative work surfaces periodically to prevent build-up of grease or
other layers that impede the static dissipation. Use only manufacturer recommended
cleaners, cleaners designed for ESD surfaces, or a mild solution of detergent and
water.
l Use conductive field service tools (ESD tools).
l Individually connect each electrostatic protected area (EPA) to the ESD ground. When
more than one ESD worksurface is in use at a workstation, each surface shall be
individually connected to the ESD ground.
l Install an earth bonding point at each EPA and directly connect it to a verified electrical
system ground or to a verified grounding bus that connects to the protective ground.
l Never ground wrist straps through a working surface, because the added resistance of
the working surface material prevents the wrist strap from operating properly.
l Never ground ESD working surfaces in series, that is, in a daisy chain.
l Connect individual bonding wires to an EPA common point ground or earth bonding
point.
l Test the EPA for continuity. You can use a surface-resistivity meter with a resistance
to ground function to test continuity from the ground point to all parts of the work area.
See the International ESD standard IEC 61340-5 for additional
information.
ELECTRIC VOLTAGEWARNING
Exercise extreme care when using energized equipment in an EPA
Ground Fault Current Interrupters should be considered to avoid shock
Most static control equipment is not designed to be used near voltages
greater than 250 volts.
