Battery Test Fail; Battery Over Charge - Tripp Lite SU60KX Manual

5 Troubleshooting (continued)
5.2 Troubleshooting Flow Charts (continued)

5.2.9 "BATTERY TEST FAIL"

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.

5.2.10 "BATTERY OVER CHARGE"

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.
Start
Are the
N
actual value
and LCD value the
same ?
Y
Battery voltage < +/-256Vdc
Check battery bank and
consider replacing the
battery
