Transportation and handling
Transport of the equipment, especially by road, must be carried out using suitable ways and means in order
to protect the components from violent shocks, humidity, vibration, etc.
Lifting
The means used for lifting must be suitable to bear the weight of the equipment.
Unpacking and checking
The components of the packaging must be removed and disposed of 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 any defects or damages are detected, please stop operating, contact the carrier and also promptly inform
the ABB Service Department.

Environmental checks
-Consult the technical data to check the environmental conditions to be observed
-Installation of the unit in a location exposed to direct sunlight must be avoided (otherwise the warranty
will be cancelled) 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
-
Always ensure that the flow of air around the inverter is not blocked so as to prevent overheating.
-
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 ex-
pected, because of the noise level that the inverter produces during operation. The level of the sound
emission is heavily influenced by where the inverter 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.
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 cause arcing (electrical discharges) that may reach the point of damaging the inverter
All installations at altitudes of over 2000 metres must be assessed case by case with the ABB
Service department.
Installation site
-Install on a wall or strong structure capable of bearing the weight of the equipment
-Install in safe, easy to reach places.
-If possible, install at eye-level so that the display can be seen easily
-Install at a height that takes account of the weight of the equipment
-Install vertically with a maximum inclination of 5° (forward or backward)
-
Choose a place that enables sufficient space to be left around the unit to enable
easy installation and removal of the object from the assembly surface; respect the
minimum distances indicated
-In the case of multiple installation position the inverters alongside each other;
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 discon
-
nection devices that may be located externally.
Please refer to the warranty terms and conditions available on the website
and evaluate any possible exclusions due to improper installation.

Wall mounting
During installation do not place the inverter with the front cover
05
facing towards the ground.
- Position the bracket
01
so that it is perfectly level on the wall and use it as a template for
drilling.
- Make the 2 holes necessary, using a drill with a 10 mm. diameter bit. The depth of the holes
must be around 70 mm.
- Secure the bracket to the wall with the two 10 mm wall plugs supplied with it.
- Attach the inverter by inserting the two tabs on the bracket
01
into the 2 slots on the inverter
(figures A1 and A2).
- Secure the inverter to the bracket by screwing the lock screws
02
on both sides of the
inverter (figure A3).
- If necessary unscrew the 8 screws and open the front cover
05
to make all accessory
connections.
Do not open the inverter in the case of rain, snow or a high level of humidity
(>95%)
• Once the connections have been made proceed to closing the cover by tightening the 8
screws on the front, adhering to the tightening sequence and torque (2.5Nm).

Check 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.
Warning! The inverters referred to in this document are TRANSFORMERLESS. This typology implies the use of insulated photovoltaic
panels (IEC61730 Class A Rating) and the need to keep the photovoltaic generator floating with respect to the ground: no terminal of the
generator must be grounded.
The inverter has a single input channel (MPPT) and is equipped with a pair of quick fit connectors
09
to
connect the PV generator
If the input strings should be connectd in parallel, they must have the same installation conditions
(number of panels in series, type of panels, orientation and inclination).
Comply with the maximum input current relating to the quick fit connectors.
-Refer to the document “String inverter – Product Manual appendix” available at www.abb.com/solarinver-
ters to know the brand and the model of the quick fit connector. Depending on the model of the connector
of the own inverter, it is necessary to use the same model and the respective counterpart (check the
compliant counterpart on the website of the manufacturer or in ABB).
Using corresponding parts that are not compliant with the quick fit connector models on the
inverter could cause serious damage to the unit and lead to invalidation of the warranty.
-Connect the DC input and always check the tightness of the connectors
