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
