Safety and Regulatory Compliance Information
packing material or if you move components across plastic or carpets. Observe
the following guidelines to minimize the potential for electrostatic discharge (ESD)
damage, which can cause intermittent or complete component failures:
Always use an ESD wrist strap or ankle strap, and make sure that it is in
direct contact with your skin.
CAUTION: For safety, periodically check the resistance value of the ESD strap. The
measurement should be in the range of 1 to 10 Mohms.
When handling any component that is removed from the chassis, make sure
the equipment end of your ESD strap is attached to one of the electrostatic
discharge points on the chassis, which are shown in Figure 1 and Figure 2.
Avoid contact between the component and your clothing. ESD voltages
emitted from clothing can still damage components.
When removing or installing a component, always place it component-side up
on an antistatic surface, in an antistatic card rack, or in an electrostatic bag
(see Figure 108). If you are returning a component, place it in an electrostatic
bag before packing it.
