Table 9. UPS Fault Codes (Continued)
Fault Code
Displayed Alarm
Potential Cause
305 RECT FAULT
Hardware fault in the rectifier /PFC
308 DC BUS SHORTED Dc bus short circuit
400 DCDC FAULT
Hardware fault in the DCDC part
500 CHARGER FAULT
Charger internal failure
502 MAX CHARGER VOLT
Recharge battery voltage is too high
503 MIN CHARGER VOLT
If battery voltage has not reached UchargeEnd
within tchargeMax then go to Float mode.
In that case if battery voltage is < 2.25 VPC then
“Charger fault” alarm is set.
tchargeMax = 24h x Number of EBM
607 BATTERY FAULT
Battery need replacement OR is faulty
700 CURRENT LIMIT
Current limitation (due to limitation, UPS has
transfered to bypass or stop)
706 UPS TEMP. FAULT
UPS internal temperature is high (due to
temperature, UPS has transfered to bypass or
stop)
70C MIN INV VOLT
Inverter voltage is too low
70D MAX INV VOLT
Inverter voltage is too high
805 OUTPUT SHORTED
short circuit on output
808 INV OVERLOAD
Inverter overload
Max (P,S) > L2 (L2 = 102%) max counter reached
C39 NVM NO RESPONSE
EEPROM can’t read/write normally
815 CALIBRATION FLT
DC offset of INV voltage is too high
00F MODEL ERROR
ATE set country error(stored in COM board
EEPROM).
Table 10. UPS Alarm Codes
