3.Note for installing the protective plate
1) 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 to the protection board J3;
5) The negative 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 / button activation;
4.dimension diagram
Size drawing of protective plate: (subject to the structure drawing, unit: mm)
Remarks: PCB size main board (bottom board) 135*126*1.6mm, slave board (upper board) 110*80*1.6mm, the overall height of the main board and auxiliary board stacked is not more than 17mm. (The pins on the smooth surface (without the original device surface) of the main board and the slave board need to be cut after soldering, the height is controlled at ≦2mm, and UV glue is applied for insulation treatment.)
5.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 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.
