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
For safe function all modules’ or the Chassis should be grounded: That is the basis of
reliability and stability of devices. Also, they are the most important guarantee of lightning
arresting and interference rejection.
Grounding connection must be installed with a 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 are well electric conducted and not
corrosive.
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 19'' rack should
be not less than 16 better 25 mm
