Please open RIB (Inp. Sw.) and BIB (Byp.
Sw.) to turn off UPS
This prompt appears when you turn off UPS.
Turn off UPS? OK or Cancel This prompt appears when you press the power button, confirm or cancel it
This operation leads to bypass over
current. OK or Cancel
This prompt appears if the bypass can’t supply load during the transfer to
bypass operation or turn off UPS operation when system work in bypass
mode, confirm or cancel it

4.4. UPS Alarm Message List
Table 4-5 , Table 4-6 , and Table 4-7 list all the UPS alarm messages based on the ‘Current’ and ‘History’ menus.
Table 4-5 UPS Alarm Message List
Alarm Meaning
Input Phase Reversed The AC input phase rotation is reversed
Input Voltage Abnormal The mains voltage is outside specifications and results in rectifier shutdown
Input Frequency Abnormal The mains frequency is outside specifications and results in rectifier shutdown
Input Undervoltage
At least one phase main input voltage is within 132 V ~ 176 V, thus the load should be
derated
Excess Auto Retransfers
The load remains on bypass power owing to excessive number of transfers that occurred
within one hour
Excess ECO Auto Transfers
The load remains on inverter power owing to excessive number of transfers that
occurred within one hour
Calibration Shutdown
For tower-type UPS calibration, select the module to be calibrated via the host software.
Shutdown for the modules not to be calibrated, and ’Calibration Shutdown’ alarm
generated
Load Sharing Abnormal The UPSs in a parallel system are not sharing the load current correctly
Inverter Asynchronous
The output voltage and bypass voltage are misaligned in phase. This alarm resets
automatically once the condition is no longer true
Overvoltage N-GND
Neutral to ground voltage is too high. Check whether the output cable is shorted to the
enclosure or not
Bypass Abnormal The amplitude or frequency of the bypass voltage exceeds the limit
Bypass Phase Reversed The phase rotation of the bypass voltage is reversed
Bypass Unable to Trace The bypass voltage and frequency are outside specifications
Bypass Overcurrent The bypass current is outside the rated current of 1.1 times
Bypass Not Available Bypass output disabled under generator mode
