Unit limitation Electrical wiring (Optional)
The machine’s microprocessor allows to limit the capacity by means of two separate criteria:
>Load limitation: The load can be varied by means of a 420 mA external signal from a BMS.
The signal cable must be directly connected to terminals 36 and 37 of the M3 terminal board.
The signal cable must be of the shielded type and must not be laid in the vicinity of the power cables, so as not
to induce interference with the electronic controller.

Current limitation: The machine’s load can be varied by means of a 420 mA external signal from an external
device. In this case, current control limits must be set on the microprocessor so that the microprocessor
transmits the value of the measured current and limits it.
The signal cable must be directly connected to terminals 36 and 37 of the M3 terminal board.
The signal cable must be of the shielded type and must not be laid in the vicinity of the power cables, so as not
to induce interference with the electronic controller.
A digital input allows to enable the current limitation at the desired time. Connect the enabling switch or the
timer (clean contact) to terminals 5 and 9.
Attention: the two options cannot be enabled simultaneously. Setting one function excludes the other.
