MESSAGE DESCRIPTION
Battery test
stopped
The battery periodic self-test or manual self-test finished
Battery to utility
transition
The UPS is powered by the mains instead of the battery
Battery voltage
abnormal
When battery is connected, the system checks that the battery voltage exceeds the normal setting range. Check
that the battery terminal voltage exceeds the normal range
Bypass
abnormal
Maybe caused by bypass voltage and frequency outside of range, bypass power-off and incorrect bypass cables
connection.
1. Check that the bypass voltage and frequency are within the setting range.
2. Check the bypass cables connection
Bypass
abnormal in
ECO mode
ayb e caused by ECO bypass voltage and frequency outside of range, ECO bypass power-off, and incorrect ECO
bypass cables connection. Check that the ECO bypass voltage and frequency are within the setting range.
Bypass mode The UPS is on bypass
Bypass
overcurrent
The bypass current exceeds the rated value.
Charger fault The charger output voltage is abnormal, and the charger will be off .
Communication
fail
Internal communication is abnormal, please check the communication cables are connected correctly or not.
DC bus
abnormal
The inverter is off when DC bus voltage is faulty. The load will transfer to bypass if the bypass is available because
the bus voltage exceeds the range.
DC/DC fault The discharger is faulty, because the bus voltage exceeds the range when discharger starts or soft starts.
EOD turn off The inverter is off due to EOD. Check the mains power-off state and recover the mains in time
Fan fault At least one fan is faulty. Check that the fan is blocked or the cables connection is loosened
Faults cleared The faults have been cleared using the Settings > Controls > Clear faults option.
Guaranteed
shutdown
Under forced EOD mode, the battery discharging finished, then system shuts down
Input abnormal
The rectifier and charger are off due to the mains voltage and frequency exceeding normalrange. Check that the
rectifier input phase voltage and frequency exceed the normal range or that the mains has power-off
Input ground
lost
Check that the PEline is well connected and that the alarm can be cleared at the display.
Input neutral
lost
The AC input mains N line is not detected. Please check that the input N line is opened or loosened
Input phase
reversed
the input live line and N line are connected incorrect
Insufficient
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
Inverter fault
The inverter is off when the inverter output voltage and current exceed the setting range. If bypass is available, the
UPS will transfer to bypass mode, otherwise the system will power off
