5.Note for installing the protective plate:

1) First connect the communication port CN1 or CN3 according to the wiring diagram of the protection board;
2) Connect the total negative electrode of the cell to the B-of the protection plate;
3) Connect the total positive electrode of the cell to the B + terminal of the protection plate;
4) Connect the cell B0.B1.B2.B3.B4.B5.B6.B7.B8.B9.B10.B11.B12.B13.B14.B15.B16 to the protection plate 1 # / 2 #;
5) The negative electrode of the load / charger is directly connected to the positive electrode of the protection plate P-;
6) The positive electrode of the load / charger is directly connected to the positive electrode P + of the protection plate;
7) Charging activation / communication activation;

6.Step of removing the protective plate:

1) Remove the communication port CN1 or CN3;
2) Remove the connection line of the P + load / charger positive electrode on the protection plate;
3) Remove the connection cable of the P-load / charger anode on the protection board;
4) Remove the cell B16.B15.B14.B13.B12.B11.B10.B9.B8.B7.B6.B5.B4.B3.B2.B1.B0 on the protective plate in sequence;
5) Remove the total positive B + connection line of the cell;
6) Finally, remove the connecting line of the total negative B-of the cell;

7.Precautions for use:

1) When connecting the battery lead, note not to misconnect or reverse connect. If the wrong lead is connected, it may cause damage to this circuit board, which should be re-tested again before use.

2) When assembly, the protective plate is careful not to directly contact the surface of the cell to avoid damage to the cell. Ensure the assembly.

3) In the process of use, pay attention to the lead head, soldering iron, solder and other components do not touch the components on the circuit board, otherwise it may lead to damage to the protection board.

4) The use process should pay attention to anti-static, moisture-proof, waterproof and other measures.

5) Please follow the designed parameters and the conditions of use during the use process, and do not exceed the relevant values in this specification, otherwise it may lead to damage to the protection plate.

6) After combining the battery pack and the protection panel, if there is no voltage output or no charge for the first time, please re-check whether the wiring is correct.
