5. Configurazione e installazione

Proper installation is critical for the safe and effective operation of your DALY BMS. It is imperative to follow the wiring sequence precisely.

5.1 Controlli pre-installazione

• Confirm your battery pack's cell count (8S-17S) and chemistry (Li-ion, LiFePO4, LTO) are compatible with this BMS model.
• Ensure all individual battery cells are balanced to a similar voltage prima di collegare il BMS.
• Verify that all cables and connectors are in good condition.

5.2 Istruzioni per il cablaggio

1. Connect the B- wire: Connect the thick black B- wire from the BMS to the negative terminal of your battery pack.
2. Connect the P- wire: Connect the thick black P- wire from the BMS to the negative terminal of your load/charger.
3. Connect the B+ wire: Connect the thick red B+ wire from the BMS to the positive terminal of your battery pack.
4. Collegare i cavi di bilanciamento: Carefully connect the balance wires (sampling cable) to each cell's positive terminal, starting from B0 (negative of the first cell) up to B17 (positive of the 17th cell), ensuring the correct sequence. Incorrect balance wire connection is a common cause of issues and can damage the BMS.
5. Connect NTC (Temperature Sensor): Connect the NTC sensor to the designated port on the BMS and place the sensor on a battery cell to monitor temperature.
6. Collegare i cavi di comunicazione: If using RS485 or CAN, connect the respective cables to the BMS and your communication device.
7. Controllo finale: Ricontrollare tutte le connessioni prima di collegare l'alimentazione.
