INAC Network supply presence check. Range 0 – 16 V
Input
4
+UN
Positive pole of DC supply voltage (10 to 30 V)
5
GND
Negative pole of DC supply voltage
6
GND
Negative pole of DC supply voltage
Note: Clamps 1-4 (+UN) and 5-6 (GND) are in the modem connect for bigger current overload.
On the power supply connector it is possible to use the signal INAC (NAP230) for
present AC voltage monitoring for power supply (it can be functional only in case of supply
accumulator backup).
Beware, on INAC (NAP230) input it isn't possible direct connect link voltage 230 V!
