2.2.3 Grounding Requirement
All function modules' good grounding is the basis of reliability and stability of devices. Also, they
are the most important guarantee of lightning arresting and interference rejection. Therefore, the
system must follow this rule.
Coaxial cables' outer conductor and isolation layer should keep proper electric conducting with
the metal housing of the device.
Grounding conductors must adopt copper conductors in order to reduce high frequency
impedance, and the grounding wire must be as thick and short as possible.
