Mains supply to DATCOM components

General

Power is supplied to DATCOM components independently of the inverter. This ensures a
power supply when there is no power from the photovoltaic modules. Power is supplied to
DATCOM components via Fronius com cards or plug-in power packs. This is particularly
important when using a Fronius Sensor Card because this ensures that the datalogger will
be able to record all data even at night.
Power supply to Fronius Com Cards are responsible for powering DATCOM components. The integrated
DATCOM compo- power supply of a Fronius Com Card is implemented via special contacts in the slot, which
nents via Fronius continue to supply power even when there is no power from the photovoltaic modules.
