Setting up the input current limit
This setting limits the input current to the charger. It can be useful when the power source (e.g. alternator) is not so
powerful. This setting can be activated in order not to stress the system. This function can only be activated by the
DIP switch, not by a external controller (display or app).
Slide the DIP switch accordingly.
