Safety Instructions
Explanation of
Symbols – Selecting a Location
DANGER! Indicates an immediate danger. Death or serious injury may result if
appropriate precautions are not taken.
WARNING! Indicates a possibly dangerous situation. Death or serious injury may
result if appropriate precautions are not taken.
CAUTION! Indicates a situation where damage or injury could occur. Minor injury
or damage to property may result if appropriate precautions are not taken.
NOTE! Indicates the possibility of flawed results and 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.
If you see any of the symbols depicted in the "Safety Rules," special care is required.
The inverter is suitable for indoor installation.
The inverter is suitable for outdoor installation.
Because of its NEMA4X protection class, the inverter is not susceptible
to hose water on any side and can also be operated in moist environments.
In order to keep inverter heating as low as possible, the inverter should
not be exposed to direct sunlight. Ideally, the inverter should be installed
in a protected location, e.g., near the solar modules or under an overhanging roof.

Do not install the inverter:
- where it may be exposed to ammonia, corrosive gases, acids or
salts
(e.g., fertilizer storage areas, vent openings for livestock stables,
chemical plants, tanneries).
During certain operation phases the inverter may produce a slight noise.
For this reason it should not be installed in an occupied living area.
Do not install the inverter in:
- areas where there is an increased risk of accidents, e.g., from farm
animals (horses, cattle, sheep, pigs, etc.)
- stables or adjoining areas
- storage areas for hay, straw, chaff, animal feed, fertilizers, etc.
The inverter is designed to be dustproof in principle. However, in areas
of high dust accumulation, the cooling surfaces can become dusty, which
can impair the thermal performance. In this case, the dust must be removed regularly. We therefore recommend that installation is not carried
out in areas and environments with high dust accumulation.
Do not install the inverter in:
- greenhouses
- storage or processing areas for fruit, vegetables, or viniculture products
- areas used in the preparation of grain, green fodder, or animal
feeds.

The inverter is suitable for vertical installation on a vertical wall or pillar.
The inverter is suitable for horizontal installation.
The inverter is suitable for installation on an inclined surface.
Do not install the inverter on an inclined surface with the connection
sockets facing upwards.
Do not install the inverter in a sloping position on a vertical wall or pillar.
Do not install the inverter in a horizontal position on a vertical wall or pillar.
Do not install the inverter on a vertical wall or pillar with the connection
sockets facing upwards.
Do not install the inverter so that it is overhanging with the connection
sockets facing upwards.

Do not install the inverter so that it is overhanging with the connection
sockets facing downwards.
Do not install the inverter on the ceiling.

Choosing the Location
Intended Use The inverter is designed exclusively to be connected and used with nongrounded solar
modules. The solar modules cannot be grounded at either the positive or negative pole.
The solar inverter is designed exclusively to convert direct current from solar modules into
alternating current and feed this power into the public grid.
The following are deemed not to be in conformity with its intended purpose:
- utilization for any other purpose, or in any other manner
- alterations to the inverter that are not expressly recommended by Fronius
- installation of components that are not expressly recommended or sold by Fronius.
The manufacturer is not responsible for any damage resulting from improper use.
All warranty claims are considered void in such cases.
Proper use also means
- carefully reading and obeying all the instructions and safety and danger notices in the
operating instructions
- carrying out all the specified inspection and servicing work
- installation as per operating instructions.
When configuring the photovoltaic system, make sure that all photovoltaic system components are operating completely within their permitted operating range.

Selecting a Location – General Information for
Fronius Primo
3.8–8.2
All measures recommended by the solar module manufacturer for maintaining solar module properties must be followed.
Utility company regulations regarding grid power feed must be followed.
Please note the following criteria when choosing a location for the inverter:
Only install on a solid surface

150 mm
Max. ambient temperatures:
-40°F to +131°F
(-40°C to +55°C)
Relative humidity:

top (cold air intake on the left and
right, hot air outflow at the top).
The waste air can reach a temperature of 70°C.
When installing the inverter in a switch cabinet or similar closed environment, it is necessary to make sure that the hot air that develops will be dissipated by forced-air ventilation.
If you wish to install the inverter on the outer walls of a cattle shed, it is important to maintain a minimum clearance of 6 ft. 7 in. (2 m) between all sides of the inverter and air vents
and other openings.
The place of installation should not be exposed to ammonia, corrosive gases, salts, or acids.

Screw Recommendation
Attaching the
Wall Bracket
IMPORTANT! Je nach Untergrund ist unterschiedliches Befestigungsmaterial für die Mon-
tage der Montagehalterung erforderlich. Das Befestigungsmaterial ist daher nicht im
Lieferumfang des Wechselrichters enthalten. Der Monteur ist für die richtige Auswahl des
Befestigungsmaterials selbst verantwortlich.
To install the inverter, the manufacturer recommends using steel or aluminum screws with
a diameter of 0.2–0.3 in. (6–8 mm).
NOTE! When attaching the wall bracket to the wall or a pillar, make sure that the
wall bracket is not warped or deformed.
