3. Lifting and transport
Transport and handling
Transportation of the equipment, especially by road, must be carried out using appropriate vehicles and methods to protect the
components (particularly electronic components) from violent shocks, humidity, vibration, etc.
Note for REACT2-BATT: the road transport is regulated by the ADR international agreement.
Lifting
FIMER usually stores and protects individual components by suitable means to make
their transport and subsequent handling easier. Nonetheless, as a rule, it is necessary
to turn to the experience of specialised staff to take charge of loading and unloading
components.
Where indicated and/or available, eyebolts or handles, which can be used as
anchorage points, are inserted and/or can be inserted.
The means used for lifting must be suitable to bear the weight of the equipment.
Equipment weight
Device Weight (kg) Lifting points
REACT2-UNO-3.6/5.0-TL < 22 kg 4 (suggested in case of 2 operators)
REACT2-BATT 50 kg 4 (suggested in case of 2 operators)
LIFTING –UThe number of required operators necessary to lift the equipment must be in accordance to local regulations relating
lifting limits per operator
Unpacking and checking
The components of the packaging must be disposed on in accordance with the regulations in force in the country of installation.
When you open the package, check that the equipment is undamaged and make sure all the components are present. If you find any

5. Choice of installation location
5.1 General recommendation on installation position
• See characteristics and technical data paragraph to check the required environmental conditions (protection rating, temperature,
humidity, altitude, etc.)
• The installation location shall be easily accessible
• The inverter operates normally up to 2000 meters; Above 2000 meters the inverter works in derating.
• Never open the REACT2-UNO in the case of rain, snow or a level of humidity >95%.
• Prevent access to the installation location by children
• Installation of the unit in a location exposed to solar rays makes the warranty void as it may cause:
-power limitation phenomena in the inverter and in the battery unit
-premature wear of the electrical/electromechanical components
-premature wear of the mechanical components (gaskets) and of the user interface (synoptic)
-reduction in performance, lifetime and possible damage of the battery unit
• Do not install in small closed rooms where air cannot circulate freely
• Always ensure that the flow of air around the inverter is not blocked so as to prevent overheating.
• Do not install in locations where flammable substances or gases may be present
• Do not install on wooden walls or near flammable substances.
• Do not install in locations with a constant presence of water and/or high humidity level.
• Respect the minimum distances from objects around the REACT2-UNO and REACT2-BATT that could prevent the inverter installation
and restrict or block the air flow.
• The installation must take account of any electrical devices (e.g. lamps, switches, etc.) which must be at least 20cm from the equipment.
These distances must be maintained also to facilitate the circulation of the air needed to cool the unit and to facilitate the operations to
install/maintain hardware and software which is done by dismantling the covers placed on the front.
• Install vertically with a maximum inclination of 5° (forward or backward).
• 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:
- Two or more REACT2-BATT can be installed one above the other.
- Do not install the REACT2-BATT above the REACT2-UNO.
• The REACT2-UNO and REACT2-BATT can be installed separately and at greater distances
• using the “REACT2-XL-CABLE-KIT” cable kit (2 meter cables length).

• Do not install in rooms where people live or where the prolonged presence of people or animals is expected, because of the noise that the
system produces during operation The level of the sound emission is heavily influenced by where the appliance is installed (for example:
the type of surface around the inverter, the general properties of the room, etc.) and the quality of the electricity supply
• Avoid electromagnetic interference that can compromise the correct operation of electronic equipment, with the consequent hazards
• The ambient temperature of the installation location should be between 5°C and 30°C to guarantee the optimal operation of the
battery unit (REACT2-BATT). Here below are the functions available from the system on the basis of the ambient temperature:
T1 - Optimal operation of the REACT2 system
T2 - Correct operation of the REACT2 system with possible reduction of power
T3 - Operation limited to the inverter part only. Management of the battery is disabled.

• Hardware and software maintenance on REACT2-UNO entails opening the front cover. Check that the correct installation safety
distances are observed in order to allow routine check and maintenance operations.
• Install on a wall or strong structure suitable to bear the weight.
• Install at a height which takes into consideration the weight of the appliance and in a position which is suitable for servicing, unless
suitable means are provided to carry out the operation.

• If possible, install at eye-level so that the synoptic can be seen easily.
• The inverter can be commissioned and monitored using the wireless communication channel. The WLAN uses radio waves to transmit
and receive data, it is therefore important to find a position for the router considering the different materials which the radio signal will
have to pass through:
Material Relative signal reduction
Open field 0% (strength of approximately 40 meters)
Wood / Glass From 0 to 10%
Stone / Plywood From 10 to 40%
Reinforced concrete From 60 to 90%
Metal Up to 100 %
ATTENTION –AFinal installation of the inverter must not compromise access to any externally located disconnection devices.
6. Mounting Instructions.

ABB B23 (58) for three-phase grid up to 65 A (it can be
used for single-phase grid if correctly installed).
ABB B24 (58) for three-phase supplies with an
external current transformer (it can be used for mono-
phase supplies if correctly installed).
The energy meter will communicate with the REACT2
through a dedicated serial line (RS485 METER).
The connection of the RS485 METER line to the REACT2-UNO must be
made using the dedicated METER connector (14).

9. Line cable and protection devices
Load protection breaker (AC disconnect switch) and line cable sizing
To protect the inverter and the AC connection line, a device must be installed to protect against maximum current and leakage to ground,
with the following characteristics:
REACT2-UNO-3.6 REACT2-UNO-5.0
Type Automatic circuit breaker with thermal-magnetic protection
Nominal Voltage 230 Vac
Nominal Current 25 A 32 A
Magnetic protection
characteristic B/C
Number of poles 2
Type of differential protection A/AC
Differential sensitivity 300 mA
In case of installation of a residual current protection device must meet the following characteristics:
REACT2-UNO-3.6 REACT2-UNO-5.0
Number of poles 2
Type of differential protection A/AC
Differential sensitivity 300 mA
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
To connect the inverter to the grid you need 4 connections: ground, neutral, phase and external grounding protection In any case,
connection of the inverter to ground is mandatory.
The connection of the grid cable to the inverter is realised through the dedicated AC output connector (17) by carrying out the following
operations:
• Characteristics and sizing of the line cable
• Installation of the cable on the AC output connector counterpart
• Connection of the AC output connector to the inverter
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.
In order to allow installation of the grid cable inside the AC output connector (20), the sizings indicated in the figure must be observed.
The table shows the maximum line conductor length in relation to the section of the conductor itself:

ATTENTION –AIn addition, the connector must not be
subject to tensile forces (examples: do not connect weights
to the AC cable, do not leave excess cable windings
hanging, etc). In order to maintain the inverter’s level of IP
protection, the corresponding part must be installed with
the AC cable connected or the protective cover, on the AC
output connector.
• Installation of the external protective grounding cable:
In addition to the grounding protection previously connected to
the AC output connector (17) is necessary to:
- install a second protective grounding cable to the dedicated
connection point on the metal frame (lower part) of the REACT2-UNO.
- install a jumper between the protective grounding connection
points on REACT2-UNO and REACT2-BATT
To execute all external grounding connection, follow the
procedure described below:
1. Make a jumper earth cable using the two cable lugs supplied
(minimum cross-section not less than 4mm²). The cable must be
long enough to connect the REACT2-UNO external protective
earth (11) to the REACT2-BATT external protective earth [A] (25)
2. From among the components supplied, find the M5 nut, M5
flat washer and M5 serrated lock washer.
3. Install the earth cables following the below installation sequence.
