carefully check before running.
2.5 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.
Grounding conductor must adopt copper conductor in order to reduce high frequency impedance,
and the grounding wire must be as thick and short as possible.
Users should make sure the 2 ends of grounding wire well electric conducted and be antirust.
It is prohibited to use any other device as part of grounding electric circuit
The area of the conduction between grounding wire and device’s frame should be no less
than 25 mm2.
