Explanation of symbols
Explanation of
safety symbols
If you see any of the symbols depicted in the "Safety rules" chapter, special care is required.
Explanation of
symbols and
choice of location
DANGER! Indicates immediate and real danger. If it is not avoided, death or se-
rious injury will result.
WARNING! Indicates a potentially dangerous situation. Death or serious injury
may result if appropriate precautions are not taken.
CAUTION! Indicates a situation where damage or injury could occur. If it is not
avoided, minor injury and/or damage to property may result.
NOTE! Indicates a risk of flawed results and possible damage to the equipment.
IMPORTANT! Indicates tips for correct operation and other particularly useful information.
It does not indicate a potentially damaging or dangerous situation.
The inverter is suitable for installation indoors.
The inverter is suitable for installation outdoors.
Its IP 65 degree of protection means that the inverter is resistant to water
jets from any direction and can also be used in damp environments.
In order to minimise the heating up of the inverter, do not expose it to direct insolation. The inverter should ideally be mounted in a protected position, e.g. in the vicinity of the solar modules or beneath the eaves.
IP 65
4
Can be used at altitudes of up to 2000 m
IMPORTANT! The inverter must not be installed or used at altitudes
above 2000 m.
Do not install the inverter:
- in areas where ammonia, corrosive vapours, acids or salts are present
(e.g. fertiliser stores, ventilation openings from cattle sheds, chemical plants, tanneries, etc.)
As the inverter generates low levels of noise at certain times, it should
not be installed close to living areas.
Do not install the inverter:
- in places where there is an increased risk of damage from farm animals (horses, cattle, sheep, pigs, etc.)
- in stables or adjoining areas
- in storage areas for hay, straw, chaff, animal feed, fertilisers, etc.
Do not install the inverter:
- in places and environments subject to heavy build-up of dust
- in places and environments in which a heavy build-up of dust containing conductive particles (e.g. iron chips) is likely
Do not install the inverter:
- in greenhouses
- in storage or processing areas for fruit, vegetables or winegrowing
products
- in places used to prepare grain, green fodder or animal feeds

Explanation of
symbols - installation position
The inverter is designed to be installed vertically on a vertical wall or pillar.
The inverter is suitable for horizontal installation.
The inverter is suitable for installation on a sloping surface.
Do not install the inverter on a sloping surface with its connection sockets
facing upwards.
Do not install the inverter at an angle on a vertical wall or pillar.
Do not install the inverter horizontally on a vertical wall or pillar.
Do not install the inverter on a vertical wall or pillar with its connection
sockets facing upwards.
Do not install the inverter such that it overhangs with its connection sockets facing upwards.

Do not install the inverter such that it overhangs with its connection sockets facing downwards.
Do not install the inverter on the ceiling.

Choice of location
Proper use The solar inverter is intended exclusively to convert direct current from solar modules into
alternating current and to feed this into the public grid.
Utilisation not in accordance with the intended purpose comprises:
- utilisation for any other purpose or in any other manner
- making any modifications to the inverter that have not been expressly approved by
Fronius
- the installation of parts that are not distributed or expressly approved by Fronius.
Fronius shall not be liable for any damage resulting from such action.
No warranty claims will be entertained.
Proper use includes:
- carefully reading and obeying all the instructions and all the safety and danger notices
in the operating instructions
- performing all stipulated inspection and maintenance work
- installation as specified in the operating instructions
When designing the photovoltaic system, ensure that all of its components are operated
within their permitted operating ranges at all times.
Observe all the measures recommended by the solar module manufacturer to ensure the
lasting maintenance of the properties of the solar module.
Obey the regulations of the energy supply company regarding feeding energy into the grid.
General comments regarding
choice of location
The following criteria should be taken into account when choosing a location for the inverter:
Install only on a solid surface
Max. ambient temperatures:
-25 °C / +50 °C
Relative humidity:
0 - 100 %
The airflow within the inverter is
from the left to the top (cold air
taken in from the left, hot air dissipated out of the top).
If the inverter is installed in a switch cabinet or a similar sealed area, then forced-air ventilation must be provided to ensure adequate heat dissipation.
If the inverter is to be installed on the outer wall of a cattle shed, maintain a minimum allround clearance of 2 m between the inverter and all ventilation and other openings in the
building.
The installation location must not be exposed to ammonia, corrosive vapours, salts or acids.
