Anti Static Protection Required
We strongly recommend you take the following anti-static precautions (listed in order of importance) to avoid
ESD (Electro Static Discharge) damage:
Leave ESD-sensitive parts in their anti-static packaging until you install them. The packaging may be a special
plastic bag or the component’s leads may be inserted in conductive foam. Parts which are especially ESD-
sensitive are identified in the parts list and in the assembly procedures.
Wear a conductive wrist strap with a series 1-megohm resistor. If you do not have a wrist strap, touch a bare
metal ground briefly before touching any sensitive parts to discharge your body. Do this frequently while you
are working. You can collect a destructive static charge on your body just sitting at the work bench.
WARNING
DO NOT attach a ground directly to yourself without a current-limiting resistor as this poses
a serious shock hazard. A wrist strap must include a 1-megohm resistor to limit the current
flow. If you choose to touch an unpainted, metal ground to discharge yourself, do it only
when you are not touching any live circuits with your other hand or any part of your body.
Use a grounded anti-static mat on your work bench.
No soldering is required but if you choose to use a soldering iron for any reason, be sure your iron has an ESD-
safe grounded tip tied to the same common ground used by your mat or wrist strap.
