2.2.3 Grounding Requirement
l
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.
l
ASI cable’s outer conductor and isolation layer should keep proper electric
conducting with the metal housing of device.
l
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.
l
Users should make sure the 2 ends of grounding wire well electric
conducted and be antirust.
l
It is prohibited to use any other device as part of grounding electric circuit
l
The area of the conduction between grounding wire and device’s frame
should be no less than 25mm

2.2.4 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

.
2.2.5 Device Grounding
Connecting the device’s grounding rod to frame’s grounding pole with copper
wire.
2.3 Wire’s Connection
The grounding wire conductive screw is located at the right end of rear panel,
and the power switch, fuse, power supply socket is just beside ,whose order
