Safety and Regulatory Compliance Information
packing material or if you move components across plastic or carpets. Observe
the following guidelines to minimize the potential f o r 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 remov ed from the chassis, make sure

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.
