First, the sequence of switching on and off. In order to avoid the damage of the UPS power supply caused by the impulse current generated at the moment of startup, in the specific use process, the UPS power supply should be powered first to make it in the bypass working state, and then turn on the load equipment one by one. This operation mode avoids the impact of the current on the UPS power supply to the greatest extent, and then extends the service life of the equipment as much as possible. The shutdown sequence is the reverse process of the startup sequence. Turn off the load equipment first, and then turn off the UPS power switch.
Second, the use environment. Similar to the environment used by computers, the use of UPS power supply is not high for temperature. Generally speaking, it can work normally as long as the temperature is maintained at 0 to 40 degrees. However, in the specific use process, we must do a good job in dust prevention. The use of UPS power supply requires a clean, less dusty and dry environment. If the external environment is dusty and humid, it will affect the normal use of UPS power supply. The battery of UPS power supply has higher requirements for temperature. The standard temperature is about 25 degrees. It is recommended that the normal use temperature should be kept between 15 and 30 degrees. Too high or too low temperature will affect the normal use of UPS power supply.
Third, safe use. The safety of UPS power supply is a matter that we need to pay attention to. The voltage of UPS power supply battery pack is high, and there is a certain risk of electric shock to human body. Therefore, safety protection should be done during assembly or unloading. The applied tools should be of insulation type, especially the output nodes, to prevent the risk of electric shock.
Fourth, charging voltage. During the charging process of UPS power supply, if the charging time is too long, the voltage will be too high and lead to overcharge. If the charging time is too short, insufficient charging will occur. Therefore, when installing specific battery packs, we must pay attention to the accuracy of battery specifications and quantities. It is recommended not to use inferior types of products for external chargers.
