power are independent to each other. Device power requires AC
power 220V 50Hz. Please carefully check before running.
2.2.3 Grounding Requirement
All function modules’ good grounding designs are the basis of reliability and stability of
electronic devices. It is the most important guarantee of surge protection and interference
rejection. Therefore, the system must be grounded.
Coaxial cable’s 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.
Make sure the 2 ends of grounding wire conduct electricity and are not rusty.
It is prohibited to use any other devices as a part of grounding electric circuit
The area of the conduction between grounding wire and device’s frame should be no less
