IMPORTANT SAFETY
INSTRUCTIONS
SAVE THESE INSTRUCTIONS
General
WARNING! Incorrect operation and work performed incorrectly
can cause serious injury & damage! Only qualified staff are
authorized to install your Fronius IG Plus and only within the
scope of the respective technical regulations. Do not start
operation or carry out maintenance work before you have read
the chapter ‘Safety Instuctions’!
The following section ‘Safety Instructions’ contains different Warnings. A
Warning describes a hazard to equipment or personnel. It calls attention
to a procedure or practice, which, if not correctly performed or adhered to,
could result in damage to or destruction of part or all of the Fronius equip-
ment and/or other equipment connected to the Fronius equipment or
personal injury.
The inverters Fronius IG Plus, Fronius IG Plus V and Fronius CL are
provided with field adjustable trip points. This manual contains important
instructions for setting the field adjustable trip points of the Fronius IG
Plus, the Fronius IG Plus V and the Fronius CL.

Safety Instructions
DANGER!
WARNING!
CAUTION!
“NOTE“ indicates a situation which could adversely affect work results and
may cause damage to equipment.

Maintenance and repair may only be carried out by an authorized specialist.
The use of third-party parts does not guarantee that they were designed and
manufactured according to operational demands and safety requirements.
Use only original spare parts (also applies to standard parts).
Do not carry out any alterations, installations or modifications to the device
without first obtaining the manufacturer’s permission.
Immediately replace any components that are not in perfect condition.
The equipment may only be operated in compliance with its intended use.
Any other purpose does not constitute intended use. The manufacturer is not
responsible for any damages resulting from unintended use.
Intended use also includes:
- reading and complying with all general information as well as safety
information and warnings from the operating instructions
- compliance with all inspection and maintenance requirements
- installation as per operating instructions
Where appropriate, the following guidelines should also be applied:
- Utility company regulations regarding grid feed-in
- Information from solar module manufacturer
Intended Use
For information about where the safety instructions and warning signs are
located on the equipment, please refer to the “General“ section of your
equipment’s operating instructions.
Any equipment malfunctions which might impair safety must be remedied
immediately before the device is turned on.
Your safety is at stake.
General
(continued)
Operation and/or storage of the device outside of the stipulated range does
not constitute intended use. The manufacturer is not responsible for any
damages resulting from unintended use.
Please refer to the technical data in your operating instructions for informati-
on about permitted ambient conditions.
Ambient Conditi-
ons
Qualified Person-
nel
The service information in these operating instructions is only intended for
qualified personnel. An electrical shock can be fatal. Please do not carry out
any activities other than those referred to in the documentation even if you
are suitably qualified.
All cables and wires must be secured, undamaged, insulated and adequately
dimensioned. Loose connections, scorched, damaged or under-dimensioned
cables and wires must be repaired immediately by an authorized specialist.

Safety Precauti-
ons at Equipment
Location
When installing devices with air vents, make sure that cool air can flow freely through the
vents unobstructed. The device should only be operated in accordance with the protec-
tion class listed on the rating plate.
EMC Device
Classifications
Devices of emission class A:
- Are only for use in industrial areas.
- Can cause line-bound and radiated interference in other areas.
Devices of emission class B:
- Meet the emission requirements 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 rating plate or technical data
EMC Precautions In special cases, there may still be interference for the specified application
area despite maintaining standardized emission limit values (e.g. when
sensitive equipment is located at the setup location or when the setup
location is near radio or television receivers).
In this case, the operator is obliged to take proper action to rectify the
situation.
Grid connection Devices with a high output (> 16 A) can influence the voltage quality of the
grid due to a high current input into the main supply.
This can affect several device types in the form of:
- Connection limitations
- Requirements regarding permitted mains impedance *)
- Requirements regarding minimum required short circuit power *)
*) for each interface to the public grid
See technical data
In this case, the operator or the user of the device must make sure whether
or not the device may be connected, if necessary by contacting the power
supply company.
Information on
Noise Emission
Values
The inverter generates a maximum sound power level of <80dB(A) (ref.
1pW) at full-load operation according to IEC 62109-1.
The cooling of the device takes place via an electronic temperature control
system at the lowest possible noise level and depends on the power used,
ambient temperature and the soiling level of the device, etc.
A workplace-related emissions value cannot be provided for this device
because the actual noise level that occurs depends strongly on the installati-
on situation, the grid quality, the surrounding walls and the general properties
of the space.

ud_fr_se_sv_01381 022009 IV
Equipment with the CE marking fulfils the basic requirements of the Guideli-
ne Governing Low-Voltage and Electromagnetic Compatibility. (For more
information, please see the attachment and/or the “Technical Data“ section in
your documentation).
Safety Markings

tions.
Copyright
This device should not be disposed of in residential waste.
To comply with European Directive 2002/96/EC on Waste Electrical and
Electronic Equipment and its implementation as national law, electrical
equipment that has reached the end of its life must be collected separately
and returned to an approved recycling facility. Any device that you no longer
require must be returned to your dealer or you must find an approved collec-
tion and recycling facility in your area.
Ignoring this EU Directive may have adverse affects on the environment and
your health.
Disposal
Danger of damage to electronic components due to electrostatic discharge.
Take appropriate ESD precautions when replacing and installing compon-
ents.
ESD Precautions
Electrical Installa-
tions
Electrical installations may only be carried out in accordance with relevant
national and local standards and regulations.
The device should only be operated when all safety equipment is fully func-
tional. If safety equipment is not fully functional, there is a danger to:
- the life and well-being of the operator or third parties
- the equipment and other property of the owner/operator
- the efficient operation of the equipment
Safety equipment that is not fully functional must be repaired by an authori-
zed specialist before the device is turned on.
Never bypass or disable safety equipment.
