UPS as a sudden power outage computer "lifeguard", has been used by more and more users, but as a relatively sophisticated equipment, how to properly use and maintain?
  UPS as a sudden power outage computer "lifeguard", has been used by more and more users, but as a relatively sophisticated equipment, how to properly use and maintain?
  1. switch sequence
In order to avoid the impact of load current generated in the starting moment ofThe damage caused by UPS power supply, in use should be the first to the UPS power supply, which is in the bypass state, one by one and then open the load, thus avoiding the impact load current of UPS, so that UPS can effectively prolong the service life of. The shutdown sequence can be viewed as the inverse process of the first boot sequence, shutting down load, and then close UPS.
  Prior to the start of the 2.
Before starting, first need to confirm the polarity of the input electrical wiring is correct, in order to ensure personal safety. Note that the total power load is not greater thanThe rated power of UPS. UPS should be avoided in the overload condition, to ensure that UPS can work normally.
  3. after the shutdown
In the power interruption after,The UPS is powered by a battery pack and automatic shutdown, stop using UPS battery powered boot, in order to avoid the damage due to excessive discharge. When the power is abnormal and converted to UPS battery power supply, should be promptly closed load and shutdown, power to normalize and start to use.
  4. the use of the environment
Similar to computer work environment,UPS requirements for environmental temperature also is not very high, usually at 0 DEG ~40 DEG can work normally. But the dust problem also plagued UPS UPS, the use of environmental requirements of clean, less dust, dry dust and humid environment will cause UPS is not working properly. UPS battery requirements on the temperature is higher, the use of standard temperature of 25 degrees centigrade, it is best not to exceed the range of 15 DEG ~30 deg. The temperature is too low will not only reduce the capacity of battery, will further affect the service life of UPS. In addition, UPS antimagnetic ability is not very good. It should not be the strong magnetic objects on UPS, otherwise it will cause damage to the machine is not working properly or UPS.
  5. battery maintenance
  The UPS battery pack will exist the phenomenon of self discharge, if not placed cause damage to the battery, so the need for regular discharge. If you are using the electrolyte absorption system of battery maintenance free, will not produce any gas in normal use, but if the user caused by improper use of the battery overcharge will produce gas, and increase the pressure within the stack, which will make the battery drum up, deformation, leakage or even rupture, user if it is found that this phenomenon should replace the battery immediately.
  6. Caution!
BecauseThe battery voltage of UPS is very high, there is a certain risk of electric shock to human body, so it has security in handling electrical connection and output line should be used, the tool should be insulated, especially the output contacts should have set to prevent electric shock. The maximum to meet more users. This is the UPS power supply enterprises need to pay attention to user complaints and feedback is one of the important reasons, only pay attention to user complaints and feedback, can in the shortest possible time to know the needs of the users and the feedback on products, in order to identify the problem, improve the product, to a greater extent to meet more users.
Pay attention to user complaints and feedback twoDo not let the user down, the user's life and work assistant
UPS power supply product function to the user will believe that the products will start to use their products. When we use the computer at work, if the power is abnormal, UPS power will persist for some time for the power supply of our computer, so we have time to deal with the hands, prevent the loss of work documents, improve the efficiency of our work. If we are not perfect, not timely processing of user complaints and other common user feedback, there are also some problems in the process of using, it will cause great inconvenience to the user; the user of products not only disappointed, also on the user's work caused a lot of trouble. Therefore, UPS power supply enterprises must pay attention to user complaints and feedback, so as to know the product and the needs of most users, users to become the life and work of the assistant for the purpose, and constantly update and improve the product.
UPS supply many brands, only for the sake of users, pay attention to user complaints and feedback, and constantly improve the product, and satisfy more users in order to win the trust of users; only pay attention to the quality of products can be abnormal when occurred in the city, to bring the real help, users become the most intimate.
