STATIC WARNING
The printed circuit cards used in this equipment contain static sensitive components. The warnings listed below
must be observed to prevent damage to these components. Disregarding any of these warnings may result in
personal injury or damage to the equipment.
1. Strictly adhere to the procedures provided in this document.
2. Before touching any static sensitive component or printed circuit card containing such a component,
discharge all static electricity from yourself by wearing a wrist strap grounded through a one megohm
resistor. Some wrist straps, such as Emerson Network Power Part Number 631810600, have a built-in
one megohm resistor; no external resistor is necessary. Read and follow wrist strap manufacturer’s
instructions outlining use of a specific wrist strap.
3. Do not touch the traces or components on a printed circuit card containing static sensitive components.
Handle the printed circuit card only by the edges that do not have connector pads.
4. After removing a printed circuit card containing a static sensitive component, place the printed circuit card
only on conductive or anti-static material such as conductive foam, conductive plastic, or aluminum foil.
Do not use ordinary Styrofoam or ordinary plastic.
5. Store and ship static sensitive devices or printed circuit cards containing such components only in static
shielding containers.
6. If necessary to repair a printed circuit card containing a static sensitive component, wear an appropriately
grounded wrist strap, work on a conductive surface, use a grounded soldering iron, and use grounded
test equipment.
