Schneider UPS power supply installation steps

UPS power supply is widely used in shopping malls, supermarkets, banks and other enterprises and institutions, the primary effect of the power supply is to provide continuous power supply for the unit in the state of power failure, so as to ensure the normal operation of the computer network system and other application systems, and effectively avoid data loss. Before using the power supply, how to use the UPS power supply device well? Trust in the UPS installation process plagues most engineering technicians. The following is a detailed explanation of the "UPS Power Supply Device Process Standard" from several aspects, such as device precautions, device process, and application precautions.

Schneider UPS power supply installation steps

1. Precautions for installation

The quality of UPS power supply devices directly affects the long-term operation of the UPS system in the future, especially the large and medium-sized UPS power supplies, so the large and medium-sized UPS power supplies should be standard in the process of planning to the device.

Generally speaking, the following elements should be considered in the installation of UPS power supply:

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

1. The status of the power grid

First of all, it includes the scale of grid voltage fluctuations, the frequency of shutdown, etc., to determine the backup time of UPS uninterruptible power supply. If necessary, other protective measures can be added in front of the UPS power supply.

2. Use the environment

Temperature: 0°C-40°C;

Humidity: 10%-90%;

Dust: The surrounding environment of UPS power supply equipment should be kept clean, which can reduce the corrosion of harmful dust on the internal circuit of UPS;

Structure: When the UPS power supply is configured with a long delay, the battery may be heavier, and the load-bearing problem of the floor should be considered at this time;

Space size: It should be ensured that when the UPS uninterruptible power supply is maintained, the engineering personnel have a certain room to play.

3. Grounding condition

In order to ensure the stable and reliable operation of the computer system, avoid parasitic capacitive coupling disturbance, and protect the safety of equipment and personnel, it is necessary to have a good grounding system. In the grounding system, the grounding resistance is used to represent the quality of the grounding, and the general grounding resistance is less than 5Ω is ideal.

Second, the device process

First, it is necessary to clarify the operating environment before proceeding with the installation. When selecting the location of the device, it is best to be free of conductive impurities and equipped with air conditioning in a separate room, the operating environment should be clean and dry, and corresponding protective measures should be taken. At the same time, the air should be free of dust and free of corrosive gases. Of course, in the normal operation of the system, it is also necessary to maintain air circulation. Therefore, when carrying out the installation, the installation environment should meet the following conditions. The operating relative humidity does not condense and the operating temperature is 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, it should be checked for damage, perhaps misfitting. If it is damaged, it should be replaced. And when unboxing, you should look at the model on the front door to match the model you ordered. In addition, it is necessary to record the model data so that it can be used in the future.

Third, you should also plan the specific path, and all the passages should be able to withstand the weight of the cabinet passing. Therefore, in this process, it is necessary to look at corridors, elevators, slopes, etc., to see if there are any dead corners. At the same time, once the power supply is in place, you should also check to see if there are other items in the cabinet.

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

Fifth, when the battery is connected with the charging device or load, the circuit switch is located in the disconnection direction to ensure that the positive and negative electrodes are connected correctly.

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

3. Precautions for use

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

2. The UPS power supply equipment is equipped with a large-capacity battery, and non-professionals should not open the case, otherwise there will be a risk of electric shock;

3. If the machine is smoking, please block the power supply quickly;

4. In case of fire around, please use a dry powder fire extinguisher, as there is a risk of electric shock when using a liquid fire extinguisher;

5. Please place the UPS mains input socket near the UPS uninterruptible power supply equipment, so that you can unplug the mains input plug and block the power supply in case of emergency.

The use of UPS power supply in the device is also a science, in the case of incorrect operation, it may form UPS power supply problems and even personal safety, so you should follow the guidance of relevant operators to use the device.
