6. Configuración e instalación

Proper installation is crucial for the safe and efficient operation of your DALY BMS. Always refer to the detailed wiring diagram provided with your product for specific connections.

Pasos generales de instalación:

1. Prepare la batería: Ensure your 16S LiFePO4 battery pack is assembled correctly and all individual cells are within a healthy voltage rango.
2. Connect B- Cable: Connect the main negative terminal (B-) of the battery pack to the B- port on the BMS.
3. Connect P- Cable: Connect the main negative output terminal (P-) for the load/charger to the P- port on the BMS.
4. Connect B+ Cable: Connect the main positive terminal (B+) of the battery pack to the B+ port on the BMS.
5. Conectar SampCables ling: Carefully connect the individual cell voltagesampling wires from your battery pack to the corresponding ports on the BMS. Ensure each wire is connected to the correct cell voltage tap, starting from B0 (negative) up to B16 (positive). Incorrect connection of sampling wires can lead to BMS malfunction or damage.
6. Conectar NTC (sensor de temperatura): Attach the NTC temperature sensor to a central location on your battery pack to monitor its temperature effectively.
7. Verificar conexiones: Verifique nuevamente todas las conexiones para verificar que sean correctas y seguras antes de aplicar energía.

Note: For parallel systems, ensure proper current limiting and follow specific guidelines for connecting multiple BMS units.
