MESSAGE DESCRIPTION
Battery test stopped The battery periodic self-test or manual self-test nished
EOD turn o The inverter is o due to EOD. Check the mains power-o state and recover the mains in time
Guaranteed shutdown Under forced EOD mode, the battery discharging nished, then system shuts down
Shutdown due to overtemp
During the UPS operation, the system checks that the heat sink temperature exceeds the setting range.
If overtemperature, please check:
Ambient temperature too high or not
Dust is blocked or not
Fan fault or not
Remote shutdown Dry contact activated at any mode shutdown
Remote power-on Remotely power on
Remote shut-o Remotely power o
Load o due to shutdown
on battery
Shutdown in battery mode
Output o due to bypass
abnormal
The bypass is abnormal, and the bypass is in standby state from working state. Check that the bypass input is normal
Battery to utility transition The UPS is powered by the mains instead of the battery
Manual power-on Set power-on via LCD panel
Manual shutdown Set shutdown via LCD panel
Operating on inverter The UPS output state is on inverter
Restore factory defaults Under UPS stand-by state, set ‘Restore Factory Defaults’ function via the Maintain page
System parallel settings
start sync
Manually set the ‘Sync parallel parameters’ command to activate the event
Local settings sync OK Local parameters are successfully synchronized
System settings sync OK All the parameters are successfully synchronized
Load o due to output short The inverter short circuit or the bypass short circuit. Please check it
Output o due to overload
& bypass abnormal
The output is o due to output overload and bypass abnormal. Please check it
Input phase reversed the input live line and N line are connected incorrect
Turn on fail
UPS get the command of start. and the mains voltage not exist or greater than 188 V, conrm 2 circulation. the prompt
will appear
Input backfeed
When the battery voltage is larger than 100 V, the absolute value of the dierence between any phase utility voltage and
battery voltage is larger than 10 V. - in such a scenario, a time frame of 6 seconds is required for conrming and ensuring
that the fault has indeed occurred
Insuicient capacity to start
The UPS is on bypass UPS get the command of start, the system load capacity is larger than 105% rated . the prompt will
appear
UPS has no output Both Inverter and Bypass provide no power supply.
Battery replacement
timeout
The alarm will appear when the time (Battery replaced time adds the noted time of battery replacement) later than the
current system time. When the users set the noted time of battery replacement as disabled, the alarm will not appear.
