User Manual For DATCOM Components

14
Power is supplied to DATCOM components independent of the Fronius IG
or Fronius IG Plus. This ensures a power supply when there is no power
from the photovoltaic modules. Power is supplied to DATCOM compon-
ents via Com cards or plug-in power packs. This is particularly important
when using a sensor card because this ensures that the Datalogger will
be able to record all data even at night.
