2. Saugos informacija

Please read and understand all safety instructions before installing or operating the DALY Smart BMS. Failure to follow these instructions may result in electric shock, fire, serious injury, or property damage.

• Always wear appropriate personal protective equipment (PPE), including safety glasses and insulated gloves, when working with batteries and electrical components.
• Ensure the battery pack is disconnected from any power source before beginning installation or maintenance.
• Verify all wiring connections are correct and secure to prevent short circuits. Incorrect wiring can damage the BMS and battery.
• Do not short-circuit any wires, especially during testing. Use insulation tape to secure any unused or excess wires.
• Keep the BMS and battery components away from water, moisture, and flammable materials.
• Do not attempt to disassemble or repair the BMS yourself. Contact qualified personnel for service.
• Ensure proper ventilation around the battery pack and BMS during operation.

4.2. Step-by-Step Wiring Instructions (Example: 8S Battery Pack)

1. Akumuliatoriaus gnybtų identifikavimas: Locate the total positive terminal and the total negative terminal of your battery pack.
2. Connect B- Wire: Connect the first black cable of the sampling wire harness and the blue B- wire to the total negative terminal of the battery pack. Ensure a secure connection.
3. Prijunkite Sampling Cables: Connect the remaining sampling cables in sequential order to the positive terminals of each cell, starting from B1, B2, B3, and so on, up to the last cell's positive terminal (e.g., B8 for an 8S pack).
   Atsargiai: If using fewer series than the maximum supported by the BMS, do not short-circuit the excess wires. Securely tape them up with insulation tape to prevent accidental contact.
4. Connect B+ Wire: Connect the red B+ wire from the sampling harness to the total positive terminal of the battery pack.
5. Patikrinkite Sampling Cable Connections: Before plugging the sampling cable into the BMS, use a multimeter to check the voltage readings. Place the black probe on B0 (the first black wire) and the red probe on B1, then B2, B3, etc. The multimeter should display positive voltage readings that increase step by step. If the readings are correct, the wiring is accurate.
   Svarbu: During this testing, do not let the two multimeter probes touch each other, as this may cause a cable short circuit.
6. Connect BMS B- Terminal: Connect the main blue B- wire from the battery pack to the B- terminal on the BMS unit.
7. Insert Temperature Sensor (NTC): Insert the NTC (temperature sensor) into the designated NTC port on the BMS.
8. Plug in Sampling Cable: Carefully plug the sampling cable harness into the corresponding port on the BMS.
9. Connect BMS B+ Wire: Connect the red B+ wire from the sampling harness to the B+ terminal on the BMS.
10. Verify BMS Power: If the green light on the BMS illuminates, the BMS is working properly and has been successfully installed.
