Handling ESD-Sensitive Parts (Aptiva 2174 - SL-A)

Many electronic parts are sensitive to electrostatic discharge (ESD). To prevent damage when working with ESD-sensitive parts, observe the following instructions. Do these in addition to taking all the usual precautions, such as switching off the power and unplugging the power cord.

•  Keep the ESD-sensitive part in its original shipping container (or special  ESD bag) until you are ready to install the part.
•  Make the fewest possible movements with your body to prevent an increase  of static electricity from clothing fibers, carpets, and furniture.
•  Put the ESD wrist strap on your wrist. Ensure the machine is turned off.  Connect the wrist strap to the serial bracket mounting screw. This  discharges any static electricity in your body to the machine frame.
•  Hold the ESD-sensitive part by its edge connector shroud (cover). Do not  touch its pins. If you are removing a plug-able module, use the correct tools.
•  Do not place the ESD-sensitive part on the machine cover or on a metal  table. If you need to put down the ESD-sensitive part for any reason, put it  into it's original container.
•  Machine covers and metal tables are electrical grounds. They increase the  risk of damage because they make a discharge path from your body  through the ESD-sensitive part. (Large metal objects can be discharge  paths without being grounded.)
•  Prevent ESD-sensitive parts from being accidentally touched by other  persons. Reinstall machine covers when you are not working on the  machine.
•  If possible, keep all ESD-sensitive parts in a grounded metal cabinet.
•  Be extra careful when working with ESD-sensitive parts while cold-weather  heating is being used. Low humidity increases static electricity.
