Characteristics

Positive Power Supply (BAT+)

Connector Pin Number	Function
P101	Battery (+) Supply Input for Internal Electronics (connected to
ADC for voltage monitoring)
P127	Battery (+) Supply Input for Power Stages
P128	Battery (+) Supply Input for Power Stages

Function Description 1 power pin = supplies internal electronics
2 power pins = parallel with 2.5mm² wires for total supply current of 25A

To operate, use at least pin 101 and either pins 127 or 128. If total load current of power stages is >17A, then use both pins are used.

Nominal supply voltage for full operation is 9 to 32V, including both supply voltage ranges for 12 and 24V battery operation. In this range, all I/Os work.
Transients exceeding this voltage are suppressed up to non-destructive limits found in max ratings.

For 12V systems, CPU works down to 4V (voltage droo until starter motor makes its first turns and battery protection limits function to 1 second).
