The wiring of UPS batteries is a crucial step in ensuring their proper functioning. When wiring, it is necessary to follow a certain sequence and precautions to ensure safety and performance. Next, we will provide a detailed introduction to the wiring method of UPS batteries.

A、 Wiring method for UPS batteries:

Detailed explanation of installation sequence

Conduct on-site investigation to determine the installation location of UPS and battery cabinet.

Start installing the battery connection cable, the specific steps are as follows:

1. Confirm the position of the battery switch, clarify the positive and negative directions of the battery in the battery cabinet, and install the air switch and wiring terminals on the battery cabinet.

2. Connect the battery cable and connect the positive terminal of the battery to the air switch.

3. Ensure that the battery wires from the next layer to the previous layer are properly wrapped with adhesive tape to prevent short circuits, and carefully check the tightening of the bolts.

4. During the connection process, it is important to distinguish between the positive and negative poles, ensuring that the positive pole is connected from the air switch to the connection terminal, while the negative pole is directly connected from the negative terminal of the battery to the connection terminal.

5. Carefully inspect the battery cabinet for any unnecessary debris.

Before connecting the battery cable from the battery cabinet to the host, use a multimeter to measure the battery voltage to 1036V and carefully check whether the positive and negative terminals are connected in reverse.

If there is a battery box, the batteries need to be connected in series and connected to the host as needed.

B、 Series connection method for multiple batteries:

When multiple batteries are needed, we need to connect them in series for wiring. The main purpose of series connection is to ensure that the battery can transmit electrical energy in sequence, thereby meeting the needs of the equipment. During the wiring process, we need to carefully confirm the positive and negative poles of each battery and connect them in the correct order. At the same time, in order to ensure the safety and stability of wiring, we also need to use appropriate connectors and insulation materials to strengthen protection. After completing the wiring, we also need to conduct strict testing to ensure that the battery can work properly and there are no safety hazards.

In situations where 8 batteries are required, we also need to use a series connection method. This wiring method also requires ensuring that the battery can transmit electrical energy one by one to meet the power requirements of the equipment. During the connection process, we also need to carefully confirm the positive and negative poles of each battery and connect them one by one in the predetermined order. In addition, to ensure the safety and stability of wiring, we also need to use suitable connectors and insulation materials to strengthen protection. Finally, after the wiring is completed, we also need to conduct comprehensive testing to ensure that the battery can work smoothly and there are no safety hazards.

C、 UPS battery wiring example:

For a 10KW UPS, it is recommended to use a 6-square-meter copper core wire, while for UPS below 10KW, it is recommended to choose a 4-square-meter copper core wire. Ensure that the selected wires meet the specifications to ensure the safety and stability of battery wiring.

Connecting the battery is a crucial step when installing a UPS power supply. The key to battery connection is to ensure that the positive and negative poles are correctly connected to achieve series connection of the batteries. After completing the series connection, two power lines need to be led out, one of which is the positive pole and the other is the negative pole, and connected to the air switch respectively.

After making the battery power cord into a plug, it can be connected to the UPS host, and the UPS host should be equipped with corresponding sockets.

UPS host input terminals usually provide two power connection methods: one is mains power connection, which is connected through 220V or 380V power supply, where the live wire should be connected to the L terminal and the neutral wire should be connected to the N terminal; The second is battery connection, which means connecting through the battery power cord that has been made into a plug.

When connecting the battery, it is necessary to ensure the correct connection of the positive and negative poles. Connect the positive pole of the battery to the positive pole of the host, and at the same time connect the negative pole of the battery to the negative pole of the host. It is strictly prohibited to connect them in reverse.

The output terminal, also known as the power interface, is specifically designed for connecting devices. When we connect the device to the output terminal of the host, the host will automatically perform voltage stabilization processing, effectively preventing instrument damage that may occur due to voltage surges.
