Note (1): To learn about EEPROM parameter settings and calibration, turn to section 3.2.

Note (2): For the location of the NH-SYS-P and/or NH-SYS-M board, turn to section 1.5. To replace the NHS-SYS-M board, remove the EEPROM chip from the old NHS-SYS-M board and insert it into the new one.

Note (1): The midpoint of the battery string must be connected to the neutral (N) of the battery terminal block.

Note (2): To learn about EEPROM parameter settings and calibration, turn to section 3.2.

Note (3): For the location of the NH-SYS-P and/or NH-SYS-M board, turn to section 1.5. To replace the NHS-SYS-M board, remove the EEPROM chip from the old NHS-SYS-M board and insert it into the new one.

Note (4): Check the battery voltage of each power module one at a time. If it is normal, check the next one.
