Transport and handling

Transport of the equipment, especially by road, must be carried out with by suitable ways and means for protecting 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 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 defects or damage, stop unpacking and consult the carrier, and also promptly inform the Service ABB.

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

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 ABB 

Service department.

Installation position

 -

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 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°

 -Choose a place with enough space around the unit to permit easy installation and 

removal of the object from the mounting surfaces; 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.

Wall/Pole mounting

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

 -Position the bracket 

01

 so that it is perfectly level on the wall and use it as a boring template.

 -

Make the 3 holes required, using a drill with a 10 mm diameter bit. The depth of the holes should 

be about 70 mm. On the bracket 

01

 there are 5 holes with which to secure it: just 3 are enough to 

support the inverter if installed on stable, robust supports.

 -Secure the bracket to the wall 

B

 or to the pole 

A

 with the no. 3 10 mm wall plugs supplied with 

it (Step 1). Check the stability of the bracket and if necessary use all the fixing points (5) there are 

on the bracket

 -Hook the inverter to the bracket spring corresponding with the insertion point in the bracket on the 

back of the inverter (Step 2).

 -Proceed to anchor the inverter to the bracket 

01

 by tightening the locking screw 

02

 located on the 

lower side (Step 3).

 -Unscrew the 4 screws and open the front cover 

05

 in order to make all the necessary connections.

 -Once the connections have been made, close the cover by tightening the 4 screws on the front to a 

minimum tightening torque of 1.5 Nm.

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 independent channels (default configuration)

This configuration involves the use of the two input channels (MPPT) in independent 

mode. This means that the jumpers between the two channels (positive and negati-

ve) of the DC input terminal block 

17

 must not be installed and the switch 

13

 located 

on the main board must be set to “IND”. N.B.: Independent channel configuration 

can only be used in the event that the negative input pole is grounded (Negative 

Grounding).

Configuration of parallel-connected channels

This configuration uses the two input channels (MPPT) connected in parallel. This 

means that the jumpers between the two channels (positive and negative) of the 

DC input terminal block 

17

 must be installed and the switch 

13

 located on the main 

board must be set to “PAR”.

The configuration of the grounding of the inputs must be done before any connections or testing takes place. No pole of the array can have 

earthing connection points located outside the inverter. Incorrect configuration may cause damage to the system and photovoltaic panels!

For the correct operation of some types of photovoltaic panels it may be necessary to ground one of the two input poles (positive or negative), or to have both 

of the input poles floating in regards to ground potential. In order to achieve this, it is possible to vary the Grounding configuration by connecting the wiring 

10

 

for connector 

09

 (negative grounding) to connector 

11

 (positive grounding), or inserting the wiring into the support provided (floating configuration).

Positive or floating grounding must NOT be used in the case of INDEPENDENT input channel configuration.
