• Make the least 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. Connect the wrist band to the system ground point. This action
discharges any static electricity in your body to the printer.
• Hold the parts by their edge connector shroud. Do not touch its pins. If you are removing a pluggable module,
then use the correct tool.
• If possible, keep all parts in a grounded metal cabinet.
• Do not place the parts on the printer cover or on a metal table. If you need to put down the parts, then put
them into their packing material.
• Prevent parts from being accidentally touched by other personnel. Cover the printer when you are not
working on it.
• Be careful while working with the parts when cold-weather heating is used. Low humidity increases static
electricity.
