Installation specifications for UPS battery cabinets and UNICELL battery racks
Installation specifications for UPS battery cabinets and battery racks. UPS battery cabinet is an intelligent distribution cabinet designed for the energy terminal of data center computer rooms, which comprehensively collects all energy data. The basic function of the UPS battery cabinet and battery rack is to accommodate and protect the battery pack. The structure must ensure that a relatively large storage space is retained and sufficient strength is met, considering the saving of layout space.
Introduction to UPS battery cabinets and racks
The UPS battery cabinet can safely and visually fit the batteries inside, while also saving space. The distribution cabinet configured for UPS is generally used for UPS output distribution, so UPS distribution boxes are generally UPS output distribution boxes. It can control power distribution units, rack mounted power distribution units, and central power distribution, making it easy to manage.
The UPS input and output distribution cabinet includes the input distribution cabinet, UPS and output distribution cabinet. The output is input to the UPS by cable. After the UPS is aligned and stored, it becomes a stable Three-phase electric power power output, which is output to the external load for power supply through the cable through the output distribution cabinet. The UPS battery cabinet also has the characteristics of aesthetics and fashion, which can also play a certain beneficial role in saving space. Although the UPS battery cabinet plays a crucial role in protecting computers, it is also important to be careful not to use it in enclosed spaces, and there should be no fire or heating sources around it, which can increase many safety hazards during use.
The UPS battery rack is used to accommodate computer equipment and other devices, which require electricity. Therefore, there are certain requirements for the chassis and cabinet, which must be equipped with a power supply. When the UPS battery cabinet is operated together with numerous devices, it will generate certain electromagnetic waves. When many electromagnetic waves converge, they will form electromagnetic interference. In order to ensure good operation results, the UPS battery cabinet needs to meet the requirements of shielding electromagnetic interference.
Installation specifications for UPS battery cabinets and battery racks
1、 Power distribution requirements
For the input and output wiring of the machine, the user electrician should connect it in advance and pull it to the machine placement point on the installation site to reserve a certain length (usually reserved 1-1.5m long), so that the machine can be installed smoothly upon arrival. For those that require factory personnel to install, users should prepare everything before the factory can send personnel to depart.
2、 Selection of entrance and exit line diameter
The selection of machine input and output wire diameters should not be lower than the national electricity safety standards.
3、 Key points of wiring
It is best to choose multi core flexible wires for all input and output copper core wires, which is convenient for user wiring and also conducive to machine wiring. The underground wiring of machine input and output should have a metal sheath.
4、 Safe grounding
Check the grounding wire to see if its grounding resistance meets national standards, which is beneficial for the safe operation of the machine and lightning protection.
5、 Balanced electricity consumption
The power distribution of three-phase electricity in the user distribution box should be balanced as much as possible. If the distribution difference is too large, it can cause excessive neutral line (zero line) current and high zero to ground voltage, which can cause unsafe machine operation and even lead to fire.
Precautions for UPS battery rack installation
● Operating environment: UPS battery racks and EPS should not be placed in a damp, dirty, or air free environment; Small UPS should not be directly stacked on the ground, and there should be padding at the bottom to prevent condensation inside the machine during spring humidity! It is best for medium and large machines to be placed in a dedicated computer room, as a good operating environment can greatly extend the service life of the machine and various loads on users.
Ventilation/load-bearing safety: The placement of the machine should ensure that the distance between the inlet/outlet air ducts of the machine and the wall is not less than 30 centimeters, in order to facilitate heat dissipation of the machine! The battery equipped for medium and large UPS long delay models also needs to consider the load-bearing pressure of the floor.
Lightning protection requirements: For UPS and EPS users in suburban and open areas, due to the limited number of high-rise buildings and the reliance on elevated lines for power transmission, elevated lines are prone to lightning strikes during thunderstorm seasons. Users should install dedicated high-power lightning protectors at the input front end of the machine to effectively avoid damage to the equipment and user loads caused by lightning.
● Initial installation inspection: Before installing large and medium-sized machines, the machine door panel should be opened to check for any looseness or detachment of various circuit boards, wiring, DC capacitors, fuse tubes, module screws, wires, mechanism components, transformers, etc. inside the machine.
What are the common sizes of UPS battery cabinets?
There is no standard for this. This specification varies from manufacturer to manufacturer. It is recommended to choose based on how many batteries your UPS requires. UPS batteries are commonly used in 8-section cabinets, 16-section cabinets, 20-section cabinets, and 32-section cabinets, which hold 8, 16, 20, and 32 100AH batteries. If the number of batteries below 50AH is doubled, and if batteries larger than 100AH need to be placed, they need to be customized and generally not available in stock.
Guidelines for the use of UPS battery cabinets
Firstly, we have learned that the characteristic of UPS power supply is its strong impact resistance. Therefore, we can pay attention to some issues when starting up. Do not turn on all load contents at the same time. You can first put it in bypass mode, then turn on the loads one by one, and finally open the UPS panel to make the entire system in inverter mode;
After the startup is agreed, the shutdown sequence is usually to first turn off the load one by one, and then turn off the UPS panel, so that the entire UPS battery is in a bypass state and charged with a charger; Secondly, when using the UPS power supply, do not let the entire load capacity be too large. In severe cases, it may cause UPS damage and bring some losses to our users;
The above is about the use of backup UPS power supply. Regarding the use of long-term UPS power supply, it is better to use an external battery pack to extend the power supply time. However, it should be noted that if installation or relocation is carried out, it is necessary to reconnect.
The above are the installation specifications for UPS battery cabinets and battery racks. There are many detailed rules for the use of UPS power batteries, and we can follow the instructions to carry out relevant operations.
