To avoid risks of electrical shock, all installation and wiring operations must be carried out with the DC disconnect 

switch internal and external (if present, applying LOTO procedures on it) to OFF position and with the external AC 

disconnect switch to OFF position (applying LOTO procedures on it).

During installation, do not place the equipment with its front facing towards the ground.

Handling of the REACT2-BATT requires two people. Do not attempt to wall mount the system alone.

•  Remove the caps from the battery and inverter connectors (if 

present).

 

-To remove the battery signal connectors 

(08)

 simply pull it.

 

-To remove the battery power connectors 

(09)

 press the latch 

(highlighted in red) and pull it off.

To avoid risks of electrical shock, all installation and wiring operations must be carried out with the DC disconnect 

switch internal and external (if present, applying LOTO procedures on it) to OFF position and with the external AC 

disconnect switch to OFF position (applying LOTO procedures on it).

•   Position the REACT2-BATT bracket 

(20)

 so that it is perfectly level on 

the wall and use it as a drilling template. To aling the two brackets use 

the reference point and follow the steps as in the picture.

•   It is the installer’s responsibility to choose an appropriate type of 

screw anchors for the attachment points. The choice must be based 

on the type of support (wall, frame or other support), the type of an-

chors to be used, and their ability to support 4 times the inverter’s 

weight (4x50Kg=200Kg). 

 Depending on the type of anchor chosen, drill the required 2 holes 

(B)

 

to mount the bracket.  

•  Install the REACT2-BATT bracket 

(20) 

to the support.

•   Lift the REACT2-BATT up to the bracket and insert the heads of two 

anchor points (present on the back of the battery unit) into the slots 

 on the bracket 

(20)

.

Risk of injury due to the heavy weight of the equipment.

•   Hang up the lower part of the REACT2-BATT to the wall using the two 

wall attachment point 

(26) 

(holes diameter 11 mm).

Environmental checks

•   See characteristics and technical data paragraph to check the re-

quired environmental conditions (protection rating, temperature, 

humidity, altitude, etc.)

•   The installation location shall be easily accessible
•  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 battery unit

 

-premature wear of the electrical/electromechanical components

 

-premature wear of the mechanical components (gaskets)

 

-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 battery unit 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.

•   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 emis-

sion is heavily influenced by where the appliance is installed (for ex-

ample: the type of surface around the inverter, the general proper-

ties of the room, etc.) and the quality of the electricity supply.

•   Respect the minimum distances from objects around the battery 

unit 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 equip-

ment. These distances must be maintained also to facilitate the cir-

culation of the air needed to cool the unit and to facilitate the opera-

tions 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 back-

ward).

•   Avoid electromagnetic interference that can compromise the correct 

operation of electronic equipment, with the consequent hazards

•  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

•  Install on a wall or strong structure suitable to bear the weight
•  The ambient temperature of the installation location should be be-

tween 5°C and 30°C to guarantee the optimal operation of the bat-

tery 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.

Final installation of the battery unit must not compromise access to any externally located disconnection devices.

•  Connect the two battery cables between inverter and bat-

tery unit (supplied inside the REACT2-UNO box).

•  Give each cable a pull test to confirm the connection 

is secure.

•   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 

Installation sequence:

knurled washers
external protective earth cable
jumper earth cable
flat washer
M5 nut (torque of 4.1 Nm)

4.  Connection on REACT2-BATT external protective earth [A] 

(25)

Follow the below installation sequence 

Installation sequence:

knurled washers
 jumper earth cable
flat washer
M5 nut (torque of 4.1 Nm)

•  Lift the REACT2-BATT up to the bracket and insert the 

heads of two anchor points (present on the back of the bat-

tery unit) into the slots 

 on the bracket 

(20)

 .

Risk of injury due to the heavy weight 

of the equipment. 

•  Hang up the lower part of the REACT2-BATT to the wall using 

the two wall attachment point 

(26)

 (holes diameter 11 mm).

The underlying procedure is related to the side-by-side installation of REACT2-BATT. Alternatively, is possible to in-

stall the REACT2-BATT separately and at greater distances using the “REACT2-XL-CABLE-KIT” cable kit (2 meter ca-

bles length).

•   Position the REACT2-BATT bracket 

(20)

 so that it is perfectly level on the wall and use it as a drilling template. To aling the two 

brackets use the reference point and follow the steps as in the picture.

•  Depending on the type of anchor chosen, drill the required 2 holes 

(B)

 to mount the bracket. 

•  Fix the REACT2-BATT bracket 

(20)

 to the support.

•  Remove the caps from the battery units connectors.

 

-To remove the battery signal connectors 

(08)

 

(22) 

simply 

pull it.

 

-To remove the battery power connectors 

(09) (23) 

press 

the latch (highlighted in red) and pull it off.

•  Connect the two battery cables between inverter and battery 

unit (supplied inside the REACT2-UNO box).

•  Give each cable a pull test to confirm the connection is secure.
•  Install an earth cable between the protective grounding con-

nection points on the two REACT2-BATTs. 

To execute all external grounding connection, follow the pro-

cedure described below:

1. From among the components supplied, find the M5 nut, M5 

flat washer and M5 serrated lock washer and two cable lugs. 

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-BATT 

external protective earth [B] 

(24)

 to the REACT2-BATT exter-

nal protective earth [A] 

(25)

.

2. Connect the cable on REACT2-BATT external protective earth 

[B] 

(24)

 of the first REACT2-BATT installed.

3. Connect the other side of the cable on REACT2-BATT external 

protective earth [A] 

(25)

.

•  For both connection follow the below installation sequence

 Installation sequence:

 knurled washers
 grounding jumper (one side)
 Flat washer
 M5 nut (torque of 4.1 Nm)
