at the Installation
Location
8
When installing devices with openings for cooling air, ensure that the cooling air can enter
and exit unhindered through the vents. Only operate the device in accordance with the degree of protection shown on the rating plate.
Data Regarding
Noise Emission
Values
The inverter generates a maximum sound power level of < 80 dB(A) (ref. 1
pW) when operating under full load in accordance with IEC 62109-1:2010.
The device is cooled as quietly as possible with the aid of an electronic temperature control system, and depends on the amount of converted power, the
ambient temperature, the level of soiling of the device, etc.
It is not possible to provide a workplace-related emission value for this device,
because the actual sound pressure level is heavily influenced by the installation situation, the power quality, the surrounding walls and the properties of
the room in general.
EN-US
EMC Device Classifications
EMC Measures
Grid Connection
Devices in emission class A:
- Are only designed for use in industrial settings
- Can cause line-bound and radiated interference in other areas
Devices in emission class B:
- Satisfy the emissions criteria for residential and industrial areas.
This is also true for residential areas in which the energy is supplied from the public low-voltage grid.
EMC device classification as per the rating plate or technical data.
In certain cases, even though a device complies with the standard limit values
for emissions, it may affect the application area for which it was designed (e.g.,
when there is sensitive equipment at the same location, or if the site where the
device is installed is close to either radio or television receivers). If this is the
case, then the operator is obliged to take appropriate action to rectify the situation.
High-performance devices (> 16 A) can affect the voltage quality of the grid
because of a high output current in the main supply.
This may affect a number of types of device in terms of:
- connection restrictions
- criteria with regard to maximum permissible mains impedance *)
- criteria with regard to minimum short-circuit power requirement *)
Electrical Installations
*) at the interface with the public grid
see Technical Data
In this case, the operator or the person using the device should check whether
or not the device is allowed to be connected, where appropriate through discussion with the power supply company.

Fronius Solar Net
- Basics
DATCOM / Plug-in
card principle
DATCOM components with external housing
Fronius Solar Net is the basis for unlimited, individual application of DATCOM components. Fronius Solar Net is a data network which enables several Fronius inverters to exchange data with DATCOM components.
The Fronius Solar Net data network operates as a ring-shaped bus system. A single data
link between the individual components enables communication between one or more Fronius inverters and the DATCOM components. This minimizes the cabling effort for the individual DATCOM components.
DATCOM components are available as plug-in cards (similar to the PC). Depending on the
country setup, Fronius inverters can be equipped with up to three plug-in cards within the
housing.
Plug-in cards communicate within the inverter via its internal network. External communication to Fronius Solar Net takes place via Fronius Com Cards.
For increased flexibility, DATCOM components are also available in versions with an external housing (box).
DATCOM components with an external housing are designed in accordance with protection class IP 20. For this reason, they are suitable for interior applications only or must be
placed in an appropriately rated weather-proof housing. If required, the base of an external
housing can be clipped onto a commercially-available DIN rail.
Maximum number
of DATCOM components and inverters
DATCOM components with external housings are
equipped with an input "IN" and output "OUT" for
data communication within the network.
The following maximum number of DATCOM components and inverters can be connected
to a total system (as of August 2016):
- 100 Fronius inverters (different models can be combined)
- 1 Fronius device with data logging function
(a list of the Fronius devices with data logging function can be found in the next section
11
"Core of Fronius Solar Net: the Datalogger“)
- 1 Fronius Power Control Card/Box
- 10 Sensor Cards/Boxes
- 10 Public Display Cards/Boxes
- 1 Interface Card/Box
- 200 Fronius String Controls
However, the system is designed to be easily upgradeable as new DATCOM components
are developed.
Core of Fronius
Solar Net: the Datalogger
The core of Fronius Solar Net is the Datalogger. It coordinates data transmissions and ensures that even large volumes of data are distributed and stored quickly and securely. In
addition, the Datalogger also records data for the entire system over long periods of time.
The following devices have a Datalogging function:
Fronius Datalogger pro
The Datalogger pro can record data from up to 100 inverters and 10 sensor cards/boxes.
Fronius Datalogger easy
The Datalogger easy can only record data from the inverter and sensor card/box using Address 1.
The Fronius Datalogger easy/pro has
- two data interfaces for direct data transfer to the PC (RS232 and USB)
- one data interface for remote PC data queries via modem and telephone line (RS232)
Fronius Datalogger Web
The Datalogger Web can record data transmitted via the Internet from up to 100 inverters
and 10 sensor cards/boxes.
The Fronius Datalogger Web has a 10/100 MBit Ethernet interface.
IMPORTANT! In the rest of this manual, the Datalogger pro, Datalogger easy and Datalogger Web are only referred to specifically if the information relates solely to that version.
The term "Datalogger" is used on its own for information that relates to Datalogger pro, Datalogger easy and Datalogger Web.
12
Fronius Personal Display DL Box
The Fronius Personal Display DL Box can record data from up to 100 inverters and one
sensor card/box.
Fronius Datamanager, Fronius Datamanager 2.0, Fronius Datamanager Box 2.0
Ethernet interface, digital inputs and outputs, antenna for WLAN, control via Modbus possible
For additional information on the Fronius Datamanager, please see the following operating
instructions:

- 42,0426,0191,xx ... Fronius Datamanager 2.0 and Fronius Datamanager Box 2.0
Fronius Com Cards provide the data link from a Fronius inverter to Fronius Solar Net and
to the DATCOM components connected to it. In addition, Fronius Com Cards also offer galvanic isolation between the photovoltaic system and the inverters, providing additional
safety. Fronius Com Cards must be installed in each inverter connected to Fronius Solar
Net.
NOTE! Every Fronius inverter to be monitored using a datalogger requires a Fronius Com Card, even if the system only contains one Fronius inverter. In this
case, the Fronius Com Card serves as a link between the internal network of the
inverter and the Fronius Solar Net interface of the Datalogger.
Each Fronius Com Card is equipped with two RS-422 interfaces – an input and an output.
The input is labeled "IN" and the output is labeled "OUT."
A Fronius Com Card is not required if
- the inverter has a Fronius Com Card function (e.g. Fronius Galvo, Fronius Symo, Fronius Eco, Fronius Primo)
- a Fronius Datamanager with Fronius Com Card function is available.

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
DATCOM components via Fronius
Com Card
Fronius Com Cards are responsible for powering DATCOM components. The integrated
power supply of a Fronius Com Card is implemented via special contacts in the slot, which
continue to supply power even when there is no power from the photovoltaic modules.
Fronius Com Cards version 1.7 and higher are equipped with a switchedmode power supply and can be used with several supply voltages (208 V / 220 V / 230 V / 240 V / 277 V).
WARNING! An electric shock can be fatal. Danger of an electrical shock due to
insufficient dimensioning for US-specific grid voltages. Fronius Com Cards up to
version 1.4B (item number 4,070,769) cannot be used with the Fronius IG Plus
USA.

Deactivating Fronius Com Cards
One Fronius Com Card can supply three additional DATCOM components, or one additional DATCOM component if it is located in a Datalogger Web. Because the power is supplied via the data cable, the DATCOM components in an external housing are also
supplied.
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.

Once cabling and installation of system components is complete, including the network
connection to all inverters, the green LED should light up on all Fronius Solar Net clients.
If this is not the case:
- Check cable connections
- Check that all inverters are connected to the network
IMPORTANT! Once the power has been turned on, the Fronius Com Card requires approx. 10 s until the green LED lights up.
If the green LED is not lit for individual system components:
- Plug another power pack into the corresponding DATCOM component
