Table 34 UPS status messages
Event Message Description / Suggested Action (if any)
Comm. Fail
The CAN communication between internal monitor and rectifier/inverter/bypass fails. Contact
Vertiv
™
Services at 800-543-2378 for assistance.
Battery Overtemp The battery temperature is over the limit. Check the battery temperature and ventilation.
Ambient Overtemp The Ambient temperature is over limit. Check the ventilation of UPS room.
Replace Battery Battery should be replaced. Contact Vertiv
™
Services at 800-543-2378 for assistance.
Battery Low Pre-warning
Before the end of discharging, battery under-voltage pre-warning should occur. After this pre-
warning, battery should have the capacity for 3 minutes discharging with full load. The time is
user configured from 3 to 60 minutes.
Shut down the load in time.
Battery End of Discharge
Inverter turned off due to low battery voltage.
Check the utility failure and try to fix it.
Input Volt. Abnormal
Mains Voltage exceeds the upper or lower limit and results in rectifier shutdown.
Check the input line-to-line voltage amplitude of rectifier.
Input Undervoltage
Mains Voltage is undervoltage (408V).
Check the input line-to-line voltage amplitude of rectifier.
Input Freq. Abnormal
Mains frequency is out of limit range and results in rectifier shutdown.
Check the rectifier’s input voltage frequency.
Rectifier Fault Rectifier Fault; Contact Vertiv
™
Services at 800-543-2378 for assistance.
Rectifier Overtemp
The temperature of heat sink is too high to keep the rectifier running.
The UPS can recover automatically. Check the environment and ventilation.
Charger Fault The Charger has failed. Contact Vertiv
™
Services at 800-543-2378 for assistance.
Input Fuse Fail Input fuse is open. Contact Vertiv
™
Services at 800-543-2378 for assistance.
Control Power Fail
Control Power has failed or has been lost. Contact Vertiv
™
Services at 800-543-2378 for
assistance.
Input Phase Reversed Input phase sequence is reversed. Contact Vertiv
™
Services at 800-543-2378 for assistance.
Soft Start Fail
Rectifier could not start due to low DC bus voltage. Contact Vertiv
™
Services at 800-543-2378
for assistance.
Bypass Unable to Trace
This alarm is triggered by an inverter software routine when the amplitude or frequency of
bypass voltage is beyond the normal range.
The amplitude threshold is fixed for positive and negative 10% rating.
This alarm automatically resets once the bypass voltage goes normal.
1. First verify that the bypass voltage and frequency displayed on the panel is within the
selected range. Note here the rated voltage and frequency are specified by “Output voltage
level” and “Output frequency level” respectively.
2. If the displayed voltage is believed to be abnormal, then verify the bypass voltage and
frequency presented to the UPS. Check the external supply if it is found to be faulty.
