Power supply connector P1 (1x4 pin)
For normal operation the external power supply has to be connected to the pins 3 (VCC) and 4 (GND) of the connector P1.
Pin 1 (VDC_AUX) is used to extend battery life time if the device main power is disabled.
Pin 2 is used as an input for either a power fail on remote on/off signal.
For details regarding the power management see separate product documentation DOC/COMPACT8-SL-E
Important
Note
Input current may vary significantly during operation. Make sure wire diameter is designed properly to
remain within the specified operating voltage range.
