Checking The Power Supply Via Fronius Com Cards; Power Pack - Fronius DATCOM Compact Manual De Instrucciones

One Fronius Com Card can supply three additional DATCOM components, or one addi-
tional DATCOM component if it is located in a Datalogger Web. Because the power is sup-
plied via the data cable, the DATCOM components in an external housing are also
supplied.
Checking the Once cabling and installation of system components is complete, including the network
power supply via connection to all inverters, the green LED should light up on all Fronius Solar Net clients.

Power pack

If there is a Fronius Datalogger Web in Solar Net, the Fronius Com Card can only supply
one additional DATCOM component, e.g., inverter + Fronius Datalogger Web + Fronius
Sensor Box. One power pack can supply up to eight DATCOM components. No additional
supply cables are needed for this. The data communication cable is used to provide power
between components.
NOTE! When using more than 12 inverters in a system, the power supply can be
deactivated for individual Fronius Com Cards to decrease the power consumption
for the DATCOM.
Check cable connections
Check that all inverters are connected to the network
Plug another power pack into the corresponding DATCOM component
Each DATCOM component with external
housing and the Fronius Com Card is
equipped with a 12 V power pack connecti-
on socket.
NOTE! If a system only has one
inverter but more than 3 DATCOM
components, the Fronius Com
Card in the inverter may not pro-
vide sufficient power for all DAT-
COM 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 components with
no green LED.
