·UPS Installation Standard

1. The fluctuation of input for UPS utility provided by the user should less than the fluctuation of UPS nominal allowed utility;

2. The former stage UPS and load loop leakage protection cannot be installed with the circuit breaker, lest causing UPS and load accident off the electricity. And frequent inserted and open should not be allowed in a circuit of live part such as electric outlet, circuit breaker;

3. The consideration of Electricity from security, input and output power distribution design should be given to the zero line (especially trunk) which can't break;

4. Do not put the UPS power output (i.e. load) from the zero line input distribution of zero line on mother row. Some brands of UPS as APC silcon series and so on, can put the input and output zero line (load) to receive the same mother row;

5. UPS input circuit breaker is designed for sole control of the hige UPS power supply input, so UPS input circuit breaker under the mouth after the power of the other is not equipped, so as not to affect the UPS input electric normal hige;

6. For UPS matching input/output circuit breaker, the first requirement of nominal rated voltage circuit breaker must conform to the UPS the rating of the input/output voltage;

7. For UPS input/output even the diameter of the selection is also irrelevant reference each phase of the maximum current, considering the three-phase equipment in the midline may exist three harmonic current, so three-phase input and output of the zero line (especially output zero line) line diameter should not be less than A phase (three-phase input and single output out photograph is usually as A bypass electricity) line diameter. Protected diameter general also irrelevant to requirements and A phase line the same size;

8. UPS and the long time delay between external battery should not be too long, or else the battery loss of pressure drop line is too big. In addition, users are paid much attention to host of environmental temperature and humidity UPS work, battery and host placed together can make battery also get good working environment;

9. It is better to use load distribution USES hierarchical way in multi-control mode. At the end of a branch happened flow or short circuit, will not cause the other branch with level or higher level power equipment off electricity, and the next level of the circuit breaker for current value should not be greater than the total amount of the higher level of 130%, appear in order to avoid the next level every branch breaker didn't carrying or overload work (circuit breaker don't trip), the higher level circuit breaker but by overload and trip, so that all the load is lost power supply;

10. Users are suggested to set alone the UPS and load, in order to make UPS and protection of the load at the focus and become reliable and easy to control. The distributor should comply with the relevant national standards;

11. Users do UPS load distribution in, UPS load with the special socket UPS load socket have a clear distinction between sign;

12. When Users in the UPS load distribution, UPS load with the special socket and UPS load socket have a clear distinction between signs in loading distribution, be sure to check that UPS load socket is zero, the polarity, and do not link in counter direction;

13. In order to provide UPS with good running environment, it needs to provide a suitable work environment temperature and, when necessary, can install air conditioning;

14. For big and medium sized UPS, the bearing of the floor should be considered in the installation;

15. For UPS external battery, it does not need the user to install by hinself, general is by UPS manufacturers and agents;

16. Regarding Users asking for 24 hour uninterrupted operation of UPS, it is necessary to equip UPS alone with a maintenance bypass distribution box.
