How to correctly use and maintain UPS uninterruptible power supply
Matters needing attention1) UPS use environment should pay attention to good ventilation, is conducive to heat dissipation, and keep the environment clean.2) do not take inductive load, such as currency counting machine, fluorescent lamp, air conditioner, etc., so as to avoid damaging the uninterrupted power supply.3) the output load of UPS is controlled at about 60%, the highest and the highest reliability.4) UPS carries too light (such as 1000VA UPS band 100VA load), may cause deep battery discharge, will reduce battery life, should be avoided as far as possible.5) the proper discharge will contribute to the activation of the battery. For example, if the electricity is not stopped for a long time, the power consumption should be artificially cut off every three months, and the load will be discharged with UPS, so that the service life of the battery can be prolonged.6) for the majority of small UPS work, open UPS, boot to avoid load startup, the work should be closed for UPS; the network room UPS, because most of the network is 24 hours of work, so UPS must also be all-weather operation.7) UPS discharge should be charged in time, so as to avoid damage to the battery due to excessive discharge.
Daily bootJust press the UPS panel "open" button, about 20 minutes later, you can open the computer or other instruments to use. Normally, when the UPS is started to work stably, the power switch of the load device can be switched on. (Note: manual maintenance switch is in "OFF" state when UPS is running normally.ShutdownTurn off the computer or other instruments, let UPS no-load run 10 minutes, standby heat after discharge, and then press the panel "off" key.
First boot(1) switch on the following sequence: energy storage battery switch, automatic bypass switch and output switch, in turn "ON"".(2) press the UPS start panel "on" button, UPS power system will start slowly, "inverter" light is on, and after 1 minutes delay, "bypass" lights go out, UPS turn to inverter power supply, complete the boot.About 10 minutes after the no-load operation, in accordance with the boot sequence from the starting load power load.
Using skillsUps - how to extend the power supply time of UPS?There are two ways to extend the power supply time of an uninterruptible power supply system:1. external high-capacity battery: can according to the required power supply time connected to the corresponding capacity of the battery group, but it should be noted that this method will cause a relative increase in battery charging time, will also increase the area and maintenance cost, so it needs to be carefully evaluated.2., buy a larger capacity uninterruptible power supply system: this method can not only reduce maintenance costs, if the load equipment expansion, the larger capacity of the uninterruptible power system can still operate immediately.
Maintain proper environmental temperature. The important factors affecting the life of the battery is environment temperature, the general requirements of the battery manufacturers best environmental temperature in degrees between 20-25. Although the temperature increases, the battery discharge capacity has improved, but the cost is to shorten the life of the battery. According to the test, once the ambient temperature is over 25 degrees centigrade, the life of the battery will be shortened by half when the temperature is increased by 10 degrees. At present, UPS batteries used are generally maintenance free sealed lead-acid batteries, the design life is generally 3 years, which is required in the battery manufacturer environment to achieve. If the environmental requirements are not met, there will be a great difference in the length of life. In addition, the environmental temperature increased, will lead to enhanced chemical activity inside the cell, resulting in a lot of heat, in turn to the ambient temperature rises, the vicious spiral, will shorten the battery life.
