Electrostatic Discharge Hazard
Wear an anti-static wrist strap with ground wire to prevent damage to
sensitive electronic components.
In addition to the usual precautions, such as turning off power before removing circuit
boards:
•
Keep the ESD-sensitive part in its original shipping container (a special "ESD bag")
until you are ready to install it.
•
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, first put it into its special bag.
•
When holding ESD-sensitive parts, limit your body movement to prevent an increase
of static electricity from clothing fibers, and furniture.
•
Hold the ESD-sensitive part by its edge connector shroud (cover); do not touch its
pins. If you are removing a plugable module, use the correct tool.
•
Be extra careful in working with ESD-sensitive parts when cold-weather heating is
used, because low humidity increases static electricity.
•
Prevent ESD-sensitive parts from being accidentally touched by other personnel.
Install machine covers when you are not working on the machine, and do not put
unprotected ESD-sensitive parts on a table.
•
If possible, keep all ESD-sensitive replacement parts stored in a grounded metal
cabinet (case) until ready for use.
