check before running.
3.2.3 Grounding Requirement
All function modules’ good grounding designs are the base of reliability and
stability of device. Also, they are the most important guarantee of lightning
arresting and interference rejection. Therefore, system must follow this rule:
1. Coaxial cable’s outer conductor and isolation layer should keep sound electric
conducting with the metal housing of device.
2. 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.
3. The 2 terminals of grounding wire must make sure for well electric conducting,
and process for antirust.
4. It is prohibited that users use other devices as part of grounding wire’s electric
circuit
3.2.3.1 Frame Grounding
All the machine frames should connect to protective copper strip. The grounding
wire should be as short as possible and avoid circling. The section of the
conjunction between grounding wire and grounding strip should be equal or
greater than 25mm2.
3.2.3.2 Device Grounding
User can connect the device’s grounding rod to frame’s grounding strip with
copper wire.
3.2.4 Wires’ Connection
The power supply outlet is located at the right of rear panel, and the power switch
is just above it. The protective grounding wire connective screw is located at the
down-right side of power supply outlet.
