3.2.1 Environmental Conditions
3.2.2 Grounding Requirement
⚫
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.
⚫
Coaxial cables’ 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.
⚫
Users should make sure the 2 ends of grounding wire well electric conducted and be antirust.
⚫
It is prohibited to use any other device as part of grounding electric circuit
⚫
The area of the conduction between grounding wire and device’s frame should be no less than 25mm

3.2.3 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

Requiring device power, air-conditioning power and lighting power are
independent to each other. Device power requires AC power 220V ±10%
50/60Hz or 110V ±10% 50/60Hz. Please carefully check before running.
