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