3.7. Electrostatic Discharge (ESD) Precautions
An ESD event occurs when two objects with different electrical charges come into contact with each other.
Electronic devices can be severely damaged by ESD.
When handling electronic modules such as disk drives, printed circuit boards (PCBs), and power supplies,
observe the following basic ESD precautions to prevent damage.
• If possible, perform any maintenance at an approved ESD-safe workstation.
• Do not unpack or install electronic modules without using a properly grounded wrist or heel strap.
• Keep all electronic modules such as power supplies, PCBs, and disk drives in their original ESD-
protective packaging until you are ready to install them.
• Handle all electronic modules carefully. Do not touch connectors, contacts, or components leads.
• Ensure that electronic modules do not come into contact with insulators such as clothing and plastics.
