Safety Precautions at the Machine Location

Information on noise emission values

EMC device classifications

EMC measures

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.

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

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.

EN

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 *)

*)	at the interface with the public mains network
see Technical Data

In this case, the plant 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.

Safety of persons

Safety
	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“!

Housing unit 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.

Galvanic insu- The design and function of the FRONIUS IG unit offer a maximum of safety, lation both during installation as well as in operation. A complete galvanic insulati-

on between DC and AC side guarantees maximum safety.

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.

Monitoring the Whenever conditions in the electric mains network are inconsistent with

electrical	standard conditions (for example mains switch-off, interruption), your
mains net-	FRONIUS IG unit will immediately stop operating and interrupt the supply
work	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	The permanent ENS mains monitoring scheme is an additional link in its
electric mains	safety chain. One of the signs by which ENS identifies abnormal situati-
network	ons in the mains is a sudden increase of the impedance in the mains
(continued)	network.
	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.
Photovoltaic	Before connecting the solar modules, you must check whether the voltage
generator	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.
	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.
Mains connec-	Only a licenced electricity installer is authorized to carry out the connec-
tion	tion works to the public mains network.
DC plugs	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 distribu-
	tion.
AC plugs	Note! Disconnect AC plug connections only when the equipment
	is not under voltage, after having disconnected the fuse for the in-
	house distribution panel.

General Introduction

How a photovoltaic system works

General infor- The energy from worldwide insolation amounts to a total of about mation 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, Alexandre-

Edmond 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.

Your roof is your power generator

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.

Power output and voltage are increased by combining a number of solar cells. If solar modules are connected in series like on a string, both the output potential as well as the voltage will increase.

In a parallel connection of several such strings the potential output and the modular electric power will increase, while the voltage will remain unchanged. The total of all solar modules connected parallel and in series is called solar generator.

The FRONIUS IG Unit in the Photovoltaic System

General infor- Your FRONIUS IG unit is the latest generation of solar inverters. It is the mation 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.

Transforming The FRONIUS IG unit transforms the direct current generated by the solar DC into AC modules into alternating current. This alternating current is fed into your electricity 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.

Fully automa- The operation of the FRONIUS IG unit is fully automatic. Starting with tic operation sunrise, as soon as the solar modules generate enough power, the auto- management matic 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!

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.

Voltage trans- The FRONIUS IG has been designed for use with solar modules of a wide formation and range of input voltages. This allows the use of the greatest variety of galvanic insu- types of solar modules. Important notice: the parameters indicated for lation 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.

EN

9

Voltage trans-	The FRONIUS IG is equipped with an HF-transformer (HF = high frequen-
formation and	cy) which assures a galvanic insulation between the DC side and the
galvanic insu-	mains. In addition, the HF principle results in a drastic reduction of the
lation	transformer’s size, which means that it requires less space and has consi-
(continued)	derably 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 The FRONIUS IG unit is in charge of monitoring the mains network. This mains network 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 func-	The complex technical systems of innovative solar inverters make it ne-
tion and data	cessary to design the display which is the interface with the user very
communicati-	carefully. It is an unwavering design aiming at ease of operation and
on	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

Your advan- With each additional task, as described above and controlled directly by tage the inverter, installation becomes easier and less costly because no addi-

tional 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).

Product description

The FRONIUS IG Unit

How it functions

Startup phase

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

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

-the display says „TEST“ and indicates the respective component which is being tested (for example „LED“)

12

Startup phase

(continued)

(3)Synchronisation with mains

-The screen displays „SYN-

CAC“

-„WAITPS“ is displayed: The

FRONIUS IG is waiting for all power supplies in the network to be on stand-by. This procedure takes place dependent on the DC-voltage.

-„SYNCAC“ is displayed subsequently.

(4)Startup test

-Before the FRONIUS IG unit starts supplying power into the mains, the conditions of the mains network are tested in detail in accordance with the regulations of your country.

-the screen displays „STARTUP“

Depending on the regulations of each country, the startup test can take between just a few seconds up to several minutes. The time elapsed is indicated by a bar shrinking from top down.

Whenever two scale divisions stop flashing and disappear, 1/10 of the total duration of the test is over

(5)Synchronisation ENS (option)

-if the FRONIUS IG unit is equipped with the ENS option, every detail of the ENS will be tested and synchronized

-the screen displays „SYNCENS“

Depending on the operating status of the ENS, test and synchronization may take up to several 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 opera- (4) LED flashes orange:

ting status	-	when a warning is being displayed on the screen
(continued)	-	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 resumed 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

Operating scheme

The Display

General information

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.
