Take the following precautions against electrostatic discharge:
• Use an anti-static bench mat and a wrist strap or ankle strap designed to safely ground
ESD potentials through a resistive element.
• Keep components in their anti-static packaging until installed.
• Avoid touching electronic components when installing a module.
