Preventing Electrostatic Discharge

• Keep the work area clear and dust free during and after installation. Do not allow dirt or debris to enter
• Keep tools and chassis components away from walk areas.
• Do not wear loose clothing, jewelry, and other items that could get caught in the chassis while working

When unpacking and setting parts aside, it is important to set them either in their original antistatic
