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

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.
The inverter is only designed to be used with non-grounded solar modules.
Improper use 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 components 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 also 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.
EN
General comments regarding
choice of location
Observe all the measures recommended by the solar module manufacturer to ensure longterm retention of the solar module's properties.
Obey the regulations of the energy supply company regarding feeding energy into the grid.
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/+45°C
-25 °C - +50 °C
(-13 °F - +122 °F)
0 - 100 %
0,3 m
(11.8 in.)
Relative humidity:
0 - 100%
The airflow within the inverter is
from the top to the rear (cold air
taken in from above, hot air dissipated out of the rear).
1,2 m
(47.2 in.)
1,2 m
(47.2 in.)
0
0
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.

Cabling and max. cable cross sections
Cabling and max.
cable cross sections
INDOOR / OUTDOOR
max. 240 mm²
AC~
DC=
The maximum cable cross section for AC and DC cables is 240 mm².
In total, 6 DC+ cables, 6 DC- cables and 6 AC cables (2x L1, 2x L2, 2x L3) can be fed into
the inverter.
If it is not possible to feed the cables into the inverter after it has been positioned, then before positioning the inverter - all AC, DC and data communication cables to be connected must
- be dimensioned accordingly,
- protrude far enough away out of the ground:
AC cable... 0.75 m
DC cable... 0.60 m
External supply... 0.40 m
Data communication cable... 2.50 m
max. 6x DC= +
max. 6x DC= max. 6x AC~
AC cables, DC cables, cables for the external supply of the inverter and, where applicable, data communication cables, must be
fed in from below the inverter (e.g. via a cable duct or a false floor).
IMPORTANT! If AC cables, DC cables and
data communication cables are fed together into the inverter, ensure adequate
insulation is provided between the AC/DC
cables and the data communication cables.

Notes regarding positioning the inverter
EN
Positioning the
inverter
IMPORTANT! Ensure that any covers which were removed previously are refitted before
the inverter is moved to its final position (e.g. fit the side cover before positioning the inverter up against a wall).
IMPORTANT! To prevent the inverter from toppling over, the inverter must be securely
fixed to the base after placing it in the final position.
Fix the inverter in place on the base, using at least 4 screws.
The fixing materials needed for this, such as screws or wall plugs, are not included in the
inverter's scope of supply. The installer is responsible for selecting the right type of fixing.
Air supply and connecting an exhaust duct
The air supply to the inverter must be at least 1200 m³/h (approx. 20 m³/min).
When connecting an exhaust duct, the back pressure it generates must not exceed 150
Pa.
This results in a volumetric flow of about 15 m³/min.

Notes regarding grid connection
Monitoring the
Grid
AC connection
area
IMPORTANT! The resistance in the leads to the AC-side connection terminals must be as
low as possible for optimal functioning of grid monitoring.
The AC connection area is located on the
rear of the inverter.
NOTE! After removing the rear
cover, unplug the grounding cable
from the cover.
The AC cable is connected via an M12 cable lug.
Connecting aluminium cables
Max. cross-section of AC cables
Fuse protection
on alternating
current side
Aluminium cables can be connected to the mains connections.
NOTE! When connecting aluminium cables:
- observe national and international guidelines regarding the connection of aluminium cables
- follow the instructions of the cable manufacturer
- check every year that the cables are securely attached in accordance with
the specified torque.
The max. cable cross-section of AC cables when feeding them in from below is 240 mm².
The fuse protection of the alternating current on the medium-voltage side depends on the
transformer available and is to be designed accordingly by the installation engineer.

General comments regarding
solar modules
DC connection
area
To enable suitable solar modules to be chosen and to use the inverter as efficiently as possible, it is important to bear the following points in mind:
- If insolation is constant and the temperature is falling, the open circuit voltage of the
solar modules will increase. The open circuit voltage must not exceed 950 V.
If the open circuit voltage exceeds 950 V, the inverter will be destroyed and no warranty claims will be entertained.
- More exact values for dimensioning the solar modules can be provided by suitable calculation programs, like the Fronius Solar.configurator (which can be downloaded from
www.fronius.com).
NOTE! Before connecting up the solar modules, check that the voltage for the solar modules specified by the manufacturer corresponds to the actual measured
voltage.
The DC connection area is located on the
lower area at the front of the inverter.
NOTE! After removing the lower
cover, unplug the grounding cable
from the cover.
Connecting aluminium cables
The DC cable is connected via a V-type terminal or alternatively using an M12 cable
lug.
IMPORTANT! Only the following cables
may be connected to V-type terminals:
- RE (round single-wire)
- RM (round multi-strand)
- SE (sector-shaped single-wire)
- SM (sector-shaped multi-strand)
- Fine-core cables, in conjunction with
ferrules only
When connecting the DC cable using an
M12 cable lug, fine-core cables are permitted.
Aluminium cables can also be connected to the DC connections.
NOTE! When connecting aluminium cables:
- observe national and international guidelines regarding the connection of aluminium cables
- follow the instructions of the cable manufacturer
- Once a year, make sure that the cables are securely connected according to
the specified torque.
Max. cross-section of DC cables
When cabling from below, the max. cable cross-section of DC cables is 240 mm².
