6. Configurazione e installazione

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.

Passaggi generali di installazione:

1. Preparare il pacco batteria: Ensure your 16S LiFePO4 battery pack is assembled correctly and all individual cells are within a healthy voltage gamma.
2. Connect B- Cable: Collegare il terminale negativo principale (B-) del pacco batteria alla porta B- del BMS.
3. Connect P- Cable: Connect the main negative output terminal (P-) for the load/charger to the P- port on the BMS.
4. Collegare il cavo B+: Connect the main positive terminal (B+) of the battery pack to the B+ port on the BMS.
5. Collega Sampling Cables: Carefully connect the individual cell voltagèampling 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. Connect NTC (Temperature Sensor): Attach the NTC temperature sensor to a central location on your battery pack to monitor its temperature effectively.
7. Verifica connessioni: Prima di alimentare l'alimentazione, verificare attentamente che tutti i collegamenti siano corretti e sicuri.

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

7. Istruzioni per l'uso
