Fire Protection
Fire alarm system and extinguisher
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
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.
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 25 ㎡.
