1. When installing NetCol5000-A35kW, how many kg of refrigerant are generally pre-filled?

2. The operation noise of the NetCol5000-A air conditioning unit is abnormal. It should be checked whether the compressor, fan, pipeline, etc. are fixed normally and there is looseness.

3. The wheel patrol function is enabled to interchange the running machine and the standby machine, thereby increasing the average life.

4. The NetCol5000-C has two installation scenarios with a chilled water distribution unit and no chilled water distribution unit.

5. When a fire occurs in the cabinet, what is used to activate the gas fire extinguishing device on site?

6. When the UPS2000-G-(6-20kVA) is in ECO mode, the battery indicator and bypass indicator are on at the same time.

7. Which part of the data center design is currently affecting its PUE?

8. Deploying on demand and avoiding over-investment is the only advantage of a modular data center.

9. When the battery is discharged, the discharge voltage of a faulty battery drops rapidly, resulting in insufficient backup time for the entire battery. What should be done?

10. What are the reasons for the excessive noise of the NetCol5000-C fan? (multiple choice)

11. How many NetCol5000-C water-cooled line-class precision air conditioners can be supported by one NetCol520 chilled water distribution unit?

12. What can convert a PoE signal into a WiFi signal?

13. What can be detected by the optional battery inspection instrument? (Multiple choice)

14. The access executor does not support access to the ECC800 in a wireless network.

A. 9Ah

B. 18Ah

C. 27Ah

D. 32Ah

17. If the UPS5000-E-400K is bypassed and the maintenance bypass is closed, both the main power module and the bypass module stop working.

18. UPS2000-G-(6-20kVA) battery discharge time is significantly lower than the standard time may be caused by what? (Multiple choice)

19. What is the correct statement about the description of UPS5000-E? (Multiple choice)
