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 device.
➢
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 mm

2.5.1
FRAME GROUNDING
All the machine frames should be connected with protective copper strip. The grounding wire
should be as short as possible and avoid circling. The area of the conduction between
grounding wire and grounding strip should be no less than 25mm

2.5.2
DEVICE GROUNDING
Connecting the device’s grounding rod to frame’s grounding pole with copper wire.
