Prompt Window
A prompt window is displayed while the system is in operation to alert you to certain conditions and/or request you
to confirm a command or other operation. Table 4-4 lists the prompts and the associated meanings.
Table 4-4 Prompts and meanings
Prompt
Meaning
System setting is different, please check
When the parallel parameters are different, this prompt will appear
Cannot set this on-line, please shut down
output
If the user attempts to change certain important settings while the output is active
(output voltage, output frequency, output phase No.), this prompt will appear
Incorrect password, please input again
This prompt will appear when the user enters an incorrect Settings password
Operation failed, condition is not met
This prompt will appear when the user attempts to execute a certain operation, but the
necessary condition is not met
Password changed OK
This prompt will appear when the user has changed the Settings password successfully
Fail to change password, please try again
This prompt will appear when the user attempts to change the Settings password but
has failed to the same new password twice
The time cannot be earlier than system time
This prompt will appear when the user sets the 'Turn on delay' or 'Turn off delay’ value
to a time earlier than the current system time
Turn on failed, condition is not met
This prompt will appear when the user presses the power button (or executes the 'Turn
on/Turn off/to Bypass' command on the 'Control' page).
Cannot set this on line, please unplug REPO
This prompt will appear if the user attempts to change output phase No. while the
output is active
Please disconnect power, check output: 1
phase, 3 phase, then power UPS on
This prompt will appear when the output phase is changed. To ensure safety, the
system requests the user to switch the UPS off and check the cable connections, and
then switch the UPS on again

UPS Alarm Message List
Table 4-5 lists all the UPS alarm messages based on the 'Current' and 'History' menus.
Table 4-5 UPS alarm message list
Alarm message
Description
Communication fail
Internal communication is abnormal, please check whether the communication cables are connected correctly
or not
Rectifier fault
The rectifier is faulty and is not running
DC/DC fault
The discharger is faulty, because the bus voltage exceeds the setting range when discharger starts or soft
starts
DC bus abnormal
The inverter is off when DC bus voltage is faulty. The load will transfer to bypass, if the bypass is available
Charger fault
The battery charger output voltage is abnormal, and the charger is off
Aux. power fault
The auxiliary power output voltage exceeds the normal range
Input backfeed
Battery mode. The mains relay is shorted and the difference between the mains and battery voltage is less
than the setting range
Inverter fault
The inverter is off when the inverter output voltage and current exceed the setting range. If the bypass is
available, the UPS will transfer to bypass mode, otherwise the system will switch off
Output short circuit
Check for short circuits between the output cables
Bypass backfeed
Battery mode. The bypass relay is shorted or the SCR is damaged
Output off, voltage is
not zero
The Output is switched off, but the system detects the presence of a voltage at the output terminals
Inverter relay shorted
The inverter relay is short circuited
Parallel No. abnormal
The on-line parallel number is inconsistent with the value in the settings. Please check that the parallel
number on the 'Settings' page is the same as the actual on-line number, and that the parallel cables are
normal
Parallel comm fault
The local UPS and its on-line frequency configuration is different or there is a conflict with the parallel
address. Please check that the parallel system parameter setting is the same as the local parameter setting
Parallel cable
connection abnormal
The system has detected that the parallel cables are not secure
