Bank system is the big users of UPS, according to a 2002 survey of the banking system accounted for almost 40% of the whole UPS sales, in the case of such a high dosage, and cultivate a large number of talents, many Banks UPS users had high attainments, it is very useful for the correct use of equipment. Bank is so much on the dosage of UPS, fully illustrates the importance of it, of course also puts forward higher requirements on its reliability. But any equipment is not absolutely reliable, always out of order, the key is what kind of failure, is congenital or acquired, of course, the bank must not choose congenital deficiency of the product, and the lack of the day after tomorrow also will lead to the loss. Therefore, in order to supply reliable will try to avoid these two problems. Statistics show that, due to less than 30% of UPS itself caused the failure, because failure is caused by natural factors and human factors and the proportion of it account for about 60% ~ 70% of the failures. If we can understand the cause of such failures and try to avoid, can avoid or reduce a lot of loss. The man-made fault or failure appeared to be real reason can be summarized as follows (in this case all cause people to panic and disturb manufacturer machine phenomenon referred to as "failure") :

1. The suspect "failure"

So-called suspected failure, as the name implies, is refers to the due to the lack of basic analytical and check-in staff did not read the instructions well and lead to misunderstanding, and this kind of misunderstanding, though not really fault, but according to the real fault handling, such as the order the manufacturer to repair or manufacturers price.mean-while loss, etc. Such as some small capacity under 10 kva UPS, instead of using liquid crystal display (LCD), mostly with 4 ~ 5 light-emitting diode LED only vertical arranged in "good" indicator light.....................

 

2. The reliability and availability

Above the man-made factors which lead to failure, understand the cause of failure, can take measures to avoid them. The quality problem of the UPS equipment itself is another serious problem. In order to avoid or reduce the fault, application in the banking system, UPS not only requires high reliability, but also must be high availability.
