3. Wrong AC input
If the RED LED is flashing and the RGB LED is flashing RED or GREEN or BLUE, it means that the
charger is detecting an incorrect AC input frequency (Hz).
The charger will continue to work to compensate for the problem and optimise the charging profile,
but the incorrect frequency of the AC line may increase or decrease the total charging time.
If this warning persists, it is advisable to check the AC mains, and the reason for the incorrect
frequency. If this type of problem continues, it may damage other electrical appliances and reduce
their efficiency.
4. Hot disconnection
The charger is capable of detecting “HOT DISCONNECTION”. In this
case, the charger will display this LED configuration for a few
seconds. The charger will then switch itself off.
If the RGB LED flashes, the charger is active. Do not
disconnect the battery!
Only when the RGB LED shows a SOLID colour (also white)
you can disconnect the battery.

Control board alarms and troubleshooting
If the RED LED Alarm/Warning is permanently lit, it means that
the charging cycle or an equalization cycle is interrupted due to
an alarm. This is in combination with the RGB LED to indicate the
problem. You can see a list of possible problems below.
