Note (1): Wire #10 connects CNP9 on the NH-SYS-P board with CNFC20 on the NH-SYS-FC board (Figure 5.2.14b).

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

Note (3): For the location of the NH-SYS-P board and NH-SYS-M boards, 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 output voltage of each power module one at a time. If normal, check the next power module.
