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.

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.
➢
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.
