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 reduc e
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.
1. Connecting power cord
2. User can insert one end into power supply outlet, while insert the other
end to AC power.
3. Connecting grounding wire
4. W hen the device solely connects to protective ground, it should adopt
independent way, say, sharing the same ground with other devices. W hen
