Note: Clamps 1-4 (+UN) and 5-6 (GND) are in the datalogger 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 connect link voltage 230 V direct !
