User Manual For DATCOM Components

27
Important Additional DATCOM components can be supplied even if they
are located in a different Fronius IG, Fronius IG Plus unit or in an external
housing.
Each DATCOM component has an LED that lights up green when there is
sufficient power. The green light for the Com cards described here indica-
tes that the integrated power supply is functioning.
NOTE When a Com card is inserted and the Fronius IG or Fronius
IG Plus is connected to the AC side, the green LED must light up.
If this is not the case, please check for the following errors:
- The Com card is not inserted correctly.
- The Fronius IG or Fronius IG Plus is not correctly connected to the
AC side.
- There is a short circuit in the connection cables to the other system
components.
- The Com card has to supply more than three DATCOM components.
If too many DATCOM components are being supplied by one Com card,
proceed as follows:
- Plug a power pack into the DATCOM component lacking the green
LED.
NOTE If a system only has one Fronius IG or Fronius IG Plus but
more than three DATCOM components, the Com card in the Fro-
nius IG or Fronius IG Plus may not provide sufficient power for all
DATCOM components. This means that the green LED would not
light up on all DATCOM components. In this case, the additional
power pack should be plugged into one of the DATCOM compon-
ents with no green LED.
For more information about Com cards, please see the chapter „Power
Supply.“
Power Supply
(continued)
The output of a Com card with an integrated power supply for additional
DATCOM components is approx. a max. of 3 W (depending on the mains
voltage).
NOTE At particularly weak points in the grid (where the AC voltage
is less than 200 V), one Com card may only be able to supply two
additional DATCOM components or only one additional DATCOM
component if it is located in a Datalogger Web.
