UPS power supply is widely used in shopping malls, supermarkets, banks and other enterprises and institutions. The main function of this power supply is to provide continuous power supply for the unit in the power outage state, thereby ensuring the normal operation of computer network systems and other application systems, and effectively avoiding data loss , To ensure fire safety. How to install the UPS power supply before use? I believe that the installation process of UPS power supply troubles most technical engineers. The following explains in detail the "UPS Power Supply Installation Process Specification" from several aspects such as installation precautions, installation process, and use precautions.

　　 1. Installation precautions

　　 The quality of UPS power installation will directly affect the long-term operation of the UPS system in the future, especially large and medium-sized UPS power supplies. Therefore, large and medium-sized UPS power supplies should be standardized from planning to installation.

　　 Generally speaking, UPS power supply mainly considers the following factors when installing:

　　 Grid conditions, load capacity, characteristics, use environment, grounding conditions, wiring, switching capacity, etc.

　　 1. Grid situation

　　 mainly includes the power grid voltage fluctuation range, working frequency, etc. to determine the UPS uninterruptible power supply backup time. If necessary, other protective measures can be added before the UPS power supply.

　　2, use environment

　　Temperature: 0℃-40℃ required;

　　Humidity: 10%-90% required;

　　 Dust: Keep the environment around the UPS power equipment clean, so as to reduce the corrosion of harmful dust on the internal circuits of the UPS;

　　 Structure: When the UPS power supply is configured with a long delay, the battery may be heavier. At this time, the floor bearing problem should be considered;

　　 Space size: It should be ensured that when UPS uninterruptible power supply is maintained, engineers have a certain amount of space for display.

　　3, grounding situation

　　In the power system, in order to ensure the stable and reliable operation of the power system, prevent parasitic capacitive coupling interference, and protect the equipment and personal safety, a good grounding system must be provided. In the grounding system, the grounding resistance is used to indicate the quality of the grounding. Generally, the grounding resistance is less than 5Ω.

　　 2. Installation process

　　 First, before proceeding with the installation, the operating environment should be clarified. When selecting the installation location, it is best to be in a separate room with no conductive impurities and equipped with air conditioning. The operating environment should be clean and dry, and appropriate protective measures should be taken. At the same time, the air should be free of dust and corrosive gases. Of course, in the normal operation of the system, air circulation should also be maintained. Therefore, when installing, the installation environment should meet the following conditions. Operating relative humidity, no condensation, operating temperature in the range of 0 to 40 degrees Celsius.

　　Second, the cabinet should be unpacked and installed, and the damage should be checked at this time. When inspecting the packaging, you should check for damage or incorrect installation. Once damaged, it should be replaced in time. When unpacking, you should check the model on the front door, which is consistent with the model ordered. And it is necessary to record the model data so that it can be used in the future.

　　 Third, we should also plan specific paths, and all channels should be able to withstand the weight of the cabinet. Therefore, in this process, it is necessary to check corridors, elevators and slopes to see if there are any blind spots. At the same time, after the power supply is in place, you should also check whether there are other items in the cabinet.

　　 Fourth, after the installation of the UPS battery system, the total voltage of the battery system and the open circuit voltage of the single battery, positive and negative polarity should be carefully checked.

　　 Fifth, when the battery is connected to the charging device or load, the circuit switch is in the off position to ensure that the positive and negative poles are connected correctly.

　　 Sixth, check the battery management parameters in the switching power supply monitoring unit, and whether the relevant parameters are consistent with those in this manual.

　　 Three, use precautions

　　 1. Do not use UPS uninterruptible power supply exceeding the rated load;

　　2, UPS power equipment is equipped with large-capacity batteries, non-professionals are not allowed to open the case, otherwise there will be a risk of electric shock;

　　 3. If the machine emits smoke, please cut off the power immediately;

　　4. In case of fire around, please use dry powder fire extinguisher, liquid fire extinguisher may cause electric shock;

　　 5. Please place the UPS power supply mains input socket near the UPS power supply equipment, so that in an emergency, unplug the mains input plug and cut off the power supply.

　　The installation and use of UPS power is also a science. In the case of incorrect operation, it may cause UPS power failure and even personal safety, so the installation and use should be guided by relevant professional staff.
