Safety Precautions at the Machine Location
Ensure when installing machines with cooling-air vents that the cooling air can flow freely
through the air vents without obstruction. Only operate the machine with the degree of
protection specified on the rating plate.
Information on
noise emission
values
EMC device
classifications
The inverter generates a maximum sound power level of <80 dB(A) (ref. 1pW)
when operating under full load in accordance with IEC 62109-1.
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.
Devices with emission class A:
- are only designed for use in an industrial setting
- can cause conducted and emitted interference in other areas.
Devices with emission class B:
- satisfy the emissions criteria for residential and industrial areas. This
also applies to residential areas in which power is supplied from the
public low-voltage grid.
EMC device classification as per the rating plate or technical specifications
EN
EMC measures 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.
Mains connection
High-performance devices (> 16 A) can affect the voltage quality on the mains
network because they can feed powerful current into 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

Safety of persons
Safety
Housing unit
Galvanic insulation
Warning! Incorrect operation and work performed incorrectly can
cause serious injury & damage! Only qualified staff are authorized to
put your FRONIUS IG unit into operation and only within the scope
of the respective technical regulations. Do not start operation or
carry out maintenance works before you have read the chapter
„Safety Conditions“!
Only qualified installers are authorized to open the connection area.
Opening the connection area is only permitted when it is not under voltage.
The separately insulation encased power stage shall only be opened
when not under voltage and only by Fronius-trained service staff.
The design and function of the FRONIUS IG unit offer a maximum of safety,
both during installation as well as in operation. A complete galvanic insulation between DC and AC side guarantees maximum safety.
Monitoring the
electrical
mains network
The FRONIUS IG takes over the tasks of galvanic insulation and network
monitoring. The passive and active measures for the protection of persons and equipment are understood by this.
Whenever conditions in the electric mains network are inconsistent with
standard conditions (for example mains switch-off, interruption), your
FRONIUS IG unit will immediately stop operating and interrupt the supply
of power into the mains.
Your FRONIUS IG unit can monitor the situation in the mains in several
ways, by
- monitoring voltage
- monitoring cycle frequency
- ENS (optional)
The ENS option is compulsory in only a few countries, and only for them
the FRONIUS IG unit is available with this option. In any case however
will the monitoring and safety systems integrated in the FRONIUS IG unit
be available as standard equipment.
4
Monitoring the
electric mains
network
(continued)
The permanent ENS mains monitoring scheme is an additional link in its
safety chain. One of the signs by which ENS identifies abnormal situations in the mains is a sudden increase of the impedance in the mains
network.
Photovoltaic
generator
Both the permanent mains monitoring by your FRONIUS IG unit directly
as well as ENS make sure that in case of a mains blackout (due to being
switched off by the utility company or due to a defect in the transmission
line) it stops feeding power into the mains.
This scheme definitely prevents dangerous voltages at the AC lines and
constitutes an essential contribution towards avoiding hazards for the
maintenance staff.
Before connecting the solar modules, you must check whether the voltage
parameters laid down in the manufacturer’s data correspond with reality.
When checking the voltage reading, please take into account that solar
modules supply a higher no-load voltage when temperatures are low and
insolation remains unchanged.
At an outside temperature of -10 degrees centigrade the no-load voltage
of the solar modules must in no case exceed 500 V - or 530 V for the IG
60 HV. The data sheet of the solar module will tell you the temperature
factors applicable for ascertaining the theoretical no-load voltage at -10
degrees centigrade.
ENEN
Mains connection
DC plugs
AC plugs
In case the solar modules exceed a no-load voltage of 500 V - or 530 V
for the IG 60 HV - the FRONIUS IG unit will be completely damaged and
all warranty rights will cease to exist.
Only a licenced electricity installer is authorized to carry out the connection works to the public mains network.
Note! If DC plugs are provided, they must never be disconnected
from the sockets of the solar modules as long as the FRONIUS IG
unit is feeding power into the mains. Before disconnecting the DC
plug you must always disconnect in the fuse for the house distribution.
Note! Disconnect AC plug connections only when the equipment
is not under voltage, after having disconnected the fuse for the inhouse distribution panel.

General Introduction
How a photovoltaic system works
ENEN
General information
Your roof is
your power
generator
The energy from worldwide insolation amounts to a total of about
1,540,000,000,000,000,000 kWh/year (1,540 Peta kWh/year). This is
15.000 times as much as the electricity consumption worldwide. We
congratulate you on your decision to actively use world’s biggest energy
pool. By the way, it was a scientist in the field of of physics, AlexandreEdmond Bequerel, who first discovered the photo-voltaic effect in 1839.
The name photo-voltaic comes from the driving force behind this technology, which is the ray of light. The ray of light consists of unimaginably tiny
particles, the photons.
Let us simply start our explanation with a straight silicon solar cell. Remembering our physics class in school, we know that there are four electrons in the outside electron shell of a silicon atom arranged around its
atomic nucleus, they are the so-called peripheral valency electrons. The
sunlight’s photons enter the solar cells and concentrate energy in the
valency electrons. The electron eventually separates from the silicon atom
and leaves behind it an atom with a positive charge.
So that the free electrons will flow in one direction and thus generate
electricity, the poles on the front and back side of the cell must be different from each other.
The silicon atoms of the front must be packed with a slight quantity of
phosphor atoms which contain an additional valency electron. On the
back of the cell, atoms of boron having only three valency electrons are
added to the silicon atoms.
The result is an imbalance which makes the electrons flow, and this is
how electric power is generated.
Many such solar cells united together and packed behind glass form one
of your solar modules.

The FRONIUS IG Unit in the Photovoltaic System
General information
Transforming
DC into AC
electricity
Fully automatic operation
management
Your FRONIUS IG unit is the latest generation of solar inverters. It is the
highly complex link between solar modules and the public electricity
mains network.
As such it is in charge of a number of highly qualified tasks.
The FRONIUS IG unit transforms the direct current generated by the solar
modules into alternating current. This alternating current is fed into your
home system or into the public mains synchronically with the voltage
which is used there. The FRONIUS IG has been designed exclusively for
use in mains connected photovoltaic schemes. It cannot generate electric
power independent from the public mains network.
The operation of the FRONIUS IG unit is fully automatic. Starting with
sunrise, as soon as the solar modules generate enough power, the automatic control unit starts monitoring voltage and frequency. As soon as
there is a sufficient level of insolation, your solar inverter starts supplying
and feeding power. A few Watts of solar power output are sufficient to
achieve this, depending on which version the unit is!
ENEN
Voltage transformation and
galvanic insulation
The operation of the FRONIUS IG unit ensures that at any time the maximum possible power output is drawn from the solar modules.
This function is called MPPT (Maximum Power Point Tracking). It operates with extremely high precision. As dusk starts there is no more sufficient energy available to feed power into the mains, the FRONIUS IG unit
shuts the mains connection completely and stops operating. All settings
and data recorded are of course saved.
The FRONIUS IG has been designed for use with solar modules of a wide
range of input voltages. This allows the use of the greatest variety of
types of solar modules. Important notice: the parameters indicated for
maximum DC voltage (total voltage of the solar cells connected) must at
no time be exceeded!
By its design and operation, the FRONIUS IG offers a maximum of safety
during installation as well as in operation.
9
Voltage transformation and
galvanic insulation
(continued)
The FRONIUS IG is equipped with an HF-transformer (HF = high frequency) which assures a galvanic insulation between the DC side and the
mains. In addition, the HF principle results in a drastic reduction of the
transformer’s size, which means that it requires less space and has considerably less weight. In spite of its full galvanic insulation, the FRONIUS IG
unit achieves a high degree of efficiency, due to its innovative circuit
schemes.
Monitoring the
mains network
The FRONIUS IG unit is in charge of monitoring the mains network. This
responsibility comprises all measures necessary for the protection of
persons and machines in case of a power blackout.
The FRONIUS IG unit is programmed to stop operation immediately and
stop supplying power whenever conditions in the mains network deviate
from standard (for example when power is switched off or in case of any
other kind of interruption).
There are several ways how the FRONIUS IG unit can identify a mainscutoff, it can do so for example by monitoring:
- voltage
- frequency
- resistance (only FRONIUS IG with ENS)
For this purpose it is important that the specific monitoring procedures
applicable for the respective countries are carried out directly by the FRONIUS IG unit without the use of additional electronic monitoring devices.
This will result in a substantial reduction of the installation work and cost.
Display function and data
communication
The complex technical systems of innovative solar inverters make it necessary to design the display which is the interface with the user very
carefully. It is an unwavering design aiming at ease of operation and
permanent availability of the system’s data.
The FRONIUS IG unit is equipped with a basic recording function for
monitoring minimum and maximum data on a daily and a cumulative
basis directly from the display. There is also an option to allow the reading
of the following weather data on the display:
- two different temperature readings (for example temperature at the
solar modules as well as the outside temperature in the shade)
- insolation
In additition to the functions installed in the FRONIUS IG unit, a wide
choice of elements offered for data communication allows for many possibilities of recording and visualising data. The respective components
required to upgrade the system are easy to install using the FRONIUS IG
DatCom operating instructions. The installation of system upgrades, such
as DatCom components, allows for possible remote system monitoring

ENEN
Your advantage
With each additional task, as described above and controlled directly by
the inverter, installation becomes easier and less costly because no additional peripheral equipment will be required. Based on our experience and
the use of the most innovative technologies, the FRONIUS IG unit is able
to manage all these tasks simultaneously.
In addition, the FRONIUS IG unit complies with a whole number of requirements established for the safety of people and other household appliances, as well for its own safety.
Some of these requirements are:
- ability to monitor the mains network
- the quality of the electricity supplied
- detection of outside disturbance and interference (for example mobile
telephones).
Annexed you will find the respective certificates.

Product description
The FRONIUS IG Unit
How it functions
The FRONIUS IG unit is designed for fully automatic operation. Basically
no personal control is necessary for feeding the power it generates into
the mains network.
The FRONIUS IG unit starts operating automatically as soon as the solar
modules produce sufficient power output after sunrise. From this point
onwards, you will also receive system information from the FRONIUS AG
graphic display.
During its operation the FRONIUS IG unit maintains the voltage of the
solar modules at any time within the range of optimal power withdrawal.
- the optimal voltage for any particular status of operation of the solar
modules is called MPP voltage (MPP = maximum power point)
- exactly maintaining the MPP voltage guarantees an optimal level of the
efficiency factor of your solar modules at any time (MPP-tracking).
As soon as dusk begins there is no more sufficient energy available to
feed into the mains network, the FRONIUS IG unit fully shuts off the
mains connection.
- during the night the FRONIUS IG unit does not draw any energy from
the public mains
- the data and parameters set remain available
- it is also possible to shut the unit off manually
Startup phase
After having switched on automatically, the FRONIUS IG unit goes through a self-test, and after that through a test of the public mains network.
This test takes between only few seconds up to several minutes, depending on the regulations in your country. During startup the LED illumination is yellow.
(1) Segment test
- all display elements light up for about one second
(2) TEST
- self test of important components of the FRONIUS IG unit
- The FRONIUS IG unit goes through a master check list for a period
of only a few seconds

LED for operating status
LED
Depending on the operating status, the LED assumes different colours
(1) LED lights up green:
- a green light starts as soon as the FRONIUS IG unit has completed
the startup phase, it stays green as long as the operation of feeding
power into the network continues
- it indicates faultless operation of the photovoltaic equipment
(2) LED flashes green:
- as long as the photovoltaic equipment is operating without fault
- and an additional message is displayed on the screen
Note! A message appears for example if there is an insulation
fault, which however does not affect the function of the FRONIUS
IG. However for safety reasons we recommend that the insulation
fault is remedied as soon as possible.
Depending on the country setup, the inverter can also disconnect
from the public grid when there is an insulation error and stop
feeding energy into the grid.
The FRONIUS IG with display shows a status message. A message is
displayed in the FRONIUS IG.access software for the FRONIUS IG without display.
If a message (e.g. „502“, Section „Status diagnosis and remedy) is shown,
rectify the relevant status and acknowledge this by pressing the „Enter“
button.
(3) LED lights up orange:
- The FRONUS IG unit will enter the automatic startup-phase, as soon
as after sunrise the photovoltaic modules yield sufficient power output

LED for operating status
(continued)
(4) LED flashes orange:
- when a warning is being displayed on the screen
- or the FRONIUS IG unit has been set to standby operation in the
setup menu = manual shutoff of power supply operation
- after the next day sunrise, power supply operation will be resu-
med automatically
- during the time while the orange LED keeps flashing, the power
supply operation can be resumed manually at any time (see
chapter „Setup Menu“)
(5) LED lights up red:
- general status: the respective service code is displayed on the
screen
Inverter does not feed energy into the public grid.
A list of all service codes, the corresponding status informations, their
status causes and repair measures can be found in the chapter „Status Diagnosis and Repair“ of the installation and service manual.
(6) LED remains dark:
- there is no connection to the solar modules
- no power output from module due to darkness

The Display
General information
Functions of
the keys
The FRONIUS IG unit is pre-configured to be ready for operation, therefore it is not necessary to make any adjustments in order to be able to get it
to operate fully automatic and feed power into the mains.
The display is powered by the solar module and is therefore available
throughout the day.
Important! The display of the FRONIUS IG is not a calibrated measuring
device. A slight deviation by a few percent is inherent in the system.
Therefore, a calibrated meter is required for accurate settlement of data
with the electricity supply company.
