Security monitoring power adapter protection
Sep 05, 2018| 1. When one end of the connecting line is connected to the battery, the other end should be insulated or held in the palm of the hand to prevent it from reaching the place where it should not be placed, causing fire;
2. One end of the cable for security monitoring is connected. When the other end is connected, you should gently click the pole to be connected. Even if it is wrong, it will only ignite on the pole and the connecting line. , does not cause a major disaster; or measure the pressure difference between the two points to be connected, zero can be connected;
3. When two people are connected at the same time, the corresponding battery pack should have no connection or potential relationship. Because the two people are at the same potential (or become the same potential at any time, such as touching the battery holder at the same time), if there is a potential difference between the connected batteries, the battery and the two people form a circuit, and an electric shock accident may occur;
4. After the battery pack is connected in series, the voltage between the total positive and negative voltage of the battery pack is relatively high. When connecting to the MCCB (battery switch), each line should be connected to the MCCB first, and then connected to the corresponding battery end; or Leave a breakpoint in the battery pack to complete the connection between the MCCB and the battery pack, and then connect the breakpoints. For multiple sets of parallel battery packs, break the head for each group and connect the MCCB end to detect the polarity with a multimeter. Then connect the broken ends.
