SEQUENTIAL CHARGING
Note: The time-delayed allocation of the charging current is not supported by all electric vehicles.
A charging current of at least 6A is required for each vehicle to be charged.
If the wallbox has been configured for a low charging current, this may mean that not both vehicles can be charged at the same
time. In this case, the two connected vehicles are charged one after the other (sequentially).
If the charging process of the second vehicle does not start automatically, it may be necessary to disconnect the vehicle from the
system for a short time first. After reconnection, the charging process starts.
As a precaution, observe the connection sequence to the box. First connect the vehicle that does not support sequential charging.
Only then connect the second vehicle (sequential charging is supported by this one).
RESTARTING THE BOX
To restart the box, first disconnect all vehicles from the system.
Switch off the wallbox's internal RCD for 5 seconds.
After switching on the voltage, the microcontroller of the box restarts automatically.
Within 2 seconds, the box signals the preselected setting by white flashing of the LEDs, 10 flashes signal a presetting of 10 amps.
INTERFACE RS 485
