3. Choice of installation location
Environmental checks
-Consult the technical data to check the environmental parameters to be observed
-Installation of the unit in a location exposed to direct sunlight must be avoided as it may cause:
1. power limitation phenomena in the inverter (with a resulting decreased energy production by the system)
2. premature wear of the electrical/electromechanical components
3. premature wear of the mechanical components (gaskets) and of the user interface (display)
-Do not install in small closed rooms where air cannot circulate freely
-To avoid overheating, always make sure the flow of air around the inverter is not blocked
-Do not install in places where gases or flammable substances may be present
-Do not install in rooms where people live or where the prolonged presence of people or animals is expected, because
of the noise (about 50dB(A) at 1 m) that the inverter makes during operation
-Avoid electromagnetic interference that can compromise the correct operation of electronic equipment, with
consequent situations of danger.
Installations above 2000 metres
On account of the rarefaction of the air (at high altitudes), particular conditions may occur:
-Less efficient cooling and therefore a greater likelihood of the device going into derating because of high internal temperatures
-Reduction in the dielectric resistance of the air that, in the presence of high operating voltages (DC input), can create electric arcs (discharges) that can
reach the point of damaging the inverter.
All installations at altitudes of over 2000 metres must be assessed case by case with the FIMER Service department.

Installation position
-Install on a wall or strong structure suitable for bearing the weight
-Install in safe, easy to reach places
-If possible, install at eye-level so that the display and status LEDs can be seen easily
-Install at a height that considers the heaviness of the equipment
-Install vertically with a maximum inclination of +/- 5°
-To carry out maintenance of the hardware and software of the equipment, remove the covers on the
front. Check that there are the correct safety distances for the installation that will allow the normal
control and maintenance operations to be carried out
-Comply with the indicated minimum distances
-For a multiple installation, position the inverters side by side
-If the space available does not allow this arrangement, position the inverters in a staggered
arrangement as shown in the figure so that heat dissipation is not affected by other inverters
Final installation of the inverter must not compromise access to any disconnection devices that may
be located externally.
Please refer to the warranty terms and conditions available on the website and evaluate any possible
exclusion due to improper installation.

8. DC input configuration
All versions of the inverter are equipped with two input channels (therefore with double maximum power
point tracker MPPT) independent of each other, which can however be connected in parallel using a single
MPPT.
- Configuration of parallel-connected channels
This configuration involves the use of the two input channels (MPPT) connected in parallel. This means
that the jumpers (12) between the two channels (positive and negative) of the DC input terminal board (13)
must be installed and that the switch a01 situated on the communication card (09) must be set to “PAR”.
- Configuration of independent channels (default configuration)
This configuration involves the use of the two input channels (MPPT) in independent mode. This means
that the jumpers (12) between the two channels (positive and negative) of the DC input terminal board (13)
must not be installed and that the switch a01 situated on the communication card (09) must be set to “IND”
9. Input connection (DC)
WARNING –BCheck for correct polarity in the input strings and absence of any leakage to ground in the PV generator.
When exposed to sunlight, the PV panels supply DC direct voltage to the inverter.
The inside of the inverter may only be accessed after the equipment has been disconnected from the grid and from the photovoltaic generator.
The inverter is only to be used with photovoltaic units with ground insulated input poles unless accessories allowing grounding of the inputs have
been installed. In this case it is compulsory to install an isolation transformer on the AC side of the system.
- Connection of inputs on the Standard and S2 models
For these two models, connection with the DC input terminal board (13) is made by inserting the cables in the DC cable glands
(11). The maximum accepted cable cross-section ranges from 10 to 17 mm, whereas each individual terminal of the terminal
board accepts a cable with cross-section of up to 50 mm2 (tightening torque 6Nm).
Unscrew the cable gland, remove the cover, insert the cable of suitable cross-section and connect it to the terminals on the
DC input terminal board (13). Once the connection to the terminal board is complete, screw in the cable gland firmly (tightening
torque 5.0Nm) and check the tightness.
- Connection of inputs on the S2F / S2X model
WARNING –BReversing polarity may result in serious damage. Always check the polarity before connecting up each
string! Each input is equipped with protection fuses: check that the fuse current rating is properly sized for the photovoltaic
modules installed.
For string connections using the S2F / S2X wiring box, the quick fit connectors (multicontact or weidmuller) situated at the bottom
of the mechanics are used.
For each input channel, there are two groups of connectors:
- Input connectors (MPPT1) (19) with codes 1A, 1B, 1C, ...
- Input connectors (MPPT2) (20) with codes 2A, 2B, 2C, ...
Connect all the strings included in the design of the system and always check the tightness of the connectors.
ATTENTION –AIn these versions of the wiring box, you MUST directly connect the individual strings coming into the
inverter (do not make field switchboards for parallel strings). This is because the string fuses (22), situated on each input,
are not sized to take strings in parallel (array).
If some string inputs are not used, check that there are covers on the connectors and install them if they are missing.
This operation is necessary for the tightness of the inverter and to avoid damaging the free connector that could be used at a later date.
10. Line cable and protection devices
Load protection breaker (AC disconnect switch) and line cable sizing
To protect the AC connection line of the inverter, we recommend installing a device for protection against over current and leakage with the following characteristics:
TRIO-20.0-TL-OUTD TRIO-27.6-TL-OUTD
Type Automatic circuit breaker with differential thermal magnetic protection
Voltage/Current rating 400V /40A 400V /63A
Magnetic protection characteristic
B/C
Number of poles 3/4
Type of differential protection A/AC
Differential sensitivity 300mA
FIMER declares that the FIMER transformerless inverters, in terms of their construction, do not inject continuous ground fault currents and therefore there
is no requirement that the differential protection installed downstream of the inverter be type B in accordance with IEC 60755 / A 2.
Characteristics and sizing of the line cable
For the connection of the inverter to the grid, you can choose between a star connection (3 phases + neutral) and a delta connection (3 phases).
The cross-section of the AC line conductor must be sized in order to prevent unwanted disconnections of the inverter from the grid due to high impedance
of the line that connects the inverter to the power supply point
Cross-section of the line conductor (mm2) Maximum length of the line conductor (m)
TRIO-20.0-TL-OUTD TRIO-27.6-TL-OUTD
10 42m 30m
16
70m 50m
25 100m 78m
35 138m 98m
The values are calculated in nominal power conditions, taking into account:
1. a power loss of not more than 1% along the line. 2. copper cable, with EPR/XLPE insulation, laid in free air

11. Output connection (AC)
For the connection of the inverter to the grid, you can choose between a star connection (3 phases + neutral) and a delta connection (3 phases).
WARNING –BIn any case, connection of the inverter to ground is mandatory.
To prevent electrocution hazards, all the connection operations must be carried out with the disconnect switch downstream of the inverter (grid side)
open and locked.
For all models, connection with the AC output terminal board (17) is made by inserting the cables in the AC cable gland (16).
The maximum accepted cable cross-section ranges from 20 to 32 mm, whereas each individual terminal of the terminal board
accepts a cable with cross-section of up to 35 mm2 (tightening torque 2.5Nm).
Unscrew the cable gland, remove the cover, insert the cable of suitable cross-section and connect the conductors(Neutral, R, S,
T and Ground) to the terminals on the AC output terminal board (17).
Be careful not to change round one of the phases with neutral!
Once the connection to the terminal board is complete, screw in the cable gland firmly (tightening torque 7.5Nm) and check the tightness.
Before connecting the inverter to the distribution grid it is necessary to set the country standard by manipulating the two rotary switches a05.
12. Setting the grid standard
Before connecting the inverter to the distribution grid it is necessary to set the country standard by manipulating the two rotary switches a05:

14. Commissioning
FORBIDDEN –HDo not place objects of any kind on the inverter during operation!
Do not touch the heatsink while the inverter is operating!Some parts may be very hot and cause burns.
The inverter commissioning procedure is as follows:
-Turn the AC+DC disconnect switch (14) to the ON position.
If there are two separate external disconnect switches (one for DC and the other for AC), first close the AC disconnect switch and then the DC disconnect
switch. There is no order of priority for opening the disconnect switches.
-When the inverter has power, the first check performed is the one relating to the input voltage:
1. If the DC input voltage is lower than the Vstart voltage (voltage required to begin the inverter’s grid connection) the b14 icon remains off and the “Waiting sun”
message is displayed b10.
2. If the DC input voltage is higher than the Vstart voltage the b14 icon is displayed and the inverter goes to the next stage of the controls.
In both cases the voltage levels and input current are displayed in the b15 and b16 fields.
-The inverter performs a control of grid parameters. The b22 icon, which represents the grid distribution, can have different statuses:
3. not present, if the mains voltage results as absent.
4. flashing, if the mains voltage is present but outside the parameters dictated by the standard of the country of installation.
5. turns on, if the mains voltage is present and within the parameters dictated by the standard of the country of installation. In this condition, the inverter starts the
sequence of grid connection.
If the input voltage and the grid voltage are within the inverter operating intervals, connection to the grid will commence. After the inverter is
connected, the icons on the whole line b21 will come on steady.
Once the connection sequence has been completed, the inverter starts to operate and indicates its correct operation by making a sound and
by the green LED coming on steady on the LED panel (25).
If the inverter signals any errors/warnings the messages and their codes will be indicated on the display (23). This state will also cause switching
