In addition to the cooling fan and circuit breaker switch components, there are a large number of solid state electronic devices in the UPS. They basically do not have mechanical wear, so they can work in the best running condition for a long time. It is necessary to find out the signs of trouble and prevent the hidden trouble from expanding, we must make the UPS work in a suitable environment and do routine maintenance. The working environment of UPS should be the same as that of the computer. The temperature should be controlled above 5 degrees Celsius and below 22 centigrade. The relative humidity should be controlled below 50%, and fluctuation range not exceeding 10%. Of course, it is equally important to these factors that keep the UPS workshop clean, dust-free, unpolluted, and harmful, as these factors also affect the service life of the UPS and cause trouble.
In the UPS daily maintenance work, engineers need daily routine inspection, its main purpose is to run the accumulated experience of online uninterruptible power supply and timely detection of fault signs, so the daily routine inspection should be careful.
