Features and Technical Data
Protection switch under load (AC switch) and sizing of the line cable
To protect the AC connection line of the inverter, we recommend the installation of a protection device against overcurrent and earth leakages with the following
features:
UNO-DM-6.0-TL-PLUS
Type Circuit breaker with differential magnetic-thermal protection
Nominal voltage 230 Vac
Nominal current 40.0 A
Magnetic protection feature B/C
Number of poles 2
Type of differential protection A/AC
Differential sensitivity 300 mA
ABB declares that the ABB high frequency inverter without a transformer are not manufactured to inject continuous currents of ground fault, and therefore, the
differential installed downstream of the inverter, type B according to IEC 60755/A 2, is not required.
Characteristics and sizing of the line cable
The cable should be three-pole. The section of the AC line conductor must be sized in order to avoid
unwanted disconnections of the inverter from the distribution network due to high impedances of the
line that connects the inverter to the point of supply of electricity.
Line conductor cross-section Maximum length of the line conductor (m)
4 mm28 m
6 mm212 m
10 mm220 m
16 mm230 m
The values are calculated in nominal power condition considering:
1. a power loss along the line of not more than 1%.
2. copper cable used, with HEPR rubber insulation and placed in open air

Caution! Before performing the operations described below, make sure that you have properly disconnected the AC line downstream of
the inverter!
For the grid connection of the inverter, 3 connections are needed: ground, neutral and phase. In any case, the earth connection of the inverter is mandatory.
The connection of the network cable to the inverter is performed by means of the AC cable gland
10
and the dedicated AC output terminal block
13
, by doing
the following:
- Strip 18 mm of sheathing from the AC grid connection cables
- Plug the AC line cable into the inverter, passing it through the AC cable gland
10
The procedure for opening the contacts of AC output terminal block
13
and tightening
cables is as follows:
1) Insert a at screwdriver in the slot behind the contacts until the clamp opens.
2) Insert the cable in the clamp with the screwdriver inserted in the slot.
3) Remove the screwdriver and check the tightness.
- Connect the protective earth (yellow-green) cable to the contact labelled with the
symbol on the terminal block
13
Warning! ABB inverters should be earthed (PE) via the terminal with the
protective earth label , using a cable with an appropriate cross-section
of the conductor for the maximum ground fault current that the generating
system might experience
- Connect the neutral cable (normally blue) to the terminal labelled with the number 1
- Connect the phase cable to the terminal labelled with the number 2
Once the connection to the terminal block
13
is complete, screw in the cable gland rmly (tightening torque 5.0Nm) and check the tightness.

- Click on “Next” button to proceed to the next stage of the conguration wizard.
The IP address assigned may vary for reasons connected to the wireless home router setup (for example, a very brief DHCP lease time). If
verication of the address is required, it is usually possible to obtain the client list (and the corresponding IP addresses) from the wireless
router administration panel.
If the inverter loses the connection with the home wireless network, it is available accessing the Wi-Fi network ABB-XX-XX-XX-XX-XX-XX, where “X” is an hexadeci-
mal number of the MAC Address.
The most common causes of losing connectivity might be: different wireless network password, faulty or unreachable router, replacement of
router (different SSID) without the necessary setting updates.
• STEP 3 - Date, Time and Time zone
- Set the Date, Time and Time zone (The inverter will propose these elds when available).
When it’s not possible for the inverter to detect the time protocol, these elds have to be manually entered.
- Click on “Next” button to proceed to the next stage of the conguration wizard.
• STEP 4 - Inverter country standard, Input mode, Meter and Energy policy.
Country standard

Custom
From the moment that the grid standard
is set, you have 24 hours to make any
changes to the value, after which the
“Country Select > Set Std.” functionality
is blocked, and the remaining time will
have to be reset in order to have the
24 hours of operation available again
in which to select a new grid standard
(follow the procedure “Resetting the re-
maining time for grid standard variation”
described in the relevant section).
See the relevant section of this guide
to know how to physically set the input
mode
If the selected meter is three-phase addi-
tional requested elds will appear:
- Meter Phase: select the phase to which
the inverter is connected.
When a meter type is selected is possible
to set also the Energy Policy elds that
allows to manage the energy produced
by the PV plant.
- Zero injection: The system automatically
manages power ows in order to avoid
the injection of energy to the grid.
- Self consumption: The system automat-
ically manages power ows in order to
maximise self-consumption.
- Custom: The system automatically
manages power ows in order to avoid
feeding the grid with power greater
than: PDC x Plim where PDC is the
power of the photovoltaic generator
(“PV GENERATOR POWER” param-
eter) and Plim is the output power limit
with respect to PDC(%) (“FEED-IN
POWER” parameter).
- Conrm the settings by clicking “DONE” and the inverter will test the meter and the battery working and it will reboot at the nish of test phase.
-
After the wizard is completed, the system will power-on. The inverter checks the grid voltage, measures the insulation resistance of the photovoltaic eld with
respect to ground and performs other auto-diagnostic checks. During the preliminary checks on the parallel connection with the grid, the “Power” LED keeps
ashing, the “Alarm” and “GFI” LEDs are off.
If the outcome of the preliminary checks on the grid parallel is positive, the inverter connects to the grid and starts to export power to the grid. The “Power” LED
remains xed on while the “Alarm” and “GFI” LEDs are off.
To address any problems that may occur during the initial stages of operation of the system and to ensure the inverter remains fully functional,
you are advised to check for any rmware updates in the download area of the website www.abb.com/solarinverters or at https://registration.
abbsolarinverters.com (instructions for registering on the website and updating the rmware are given in this manual).
Before proceeding with commissioning, make sure you have carried out all the following checks:
-Check the correct connection and polarity of the DC inputs, and the correct connection of the AC output and ground cables.
-Check the sealing barrier of the cable ducts and installed quick-t connectors to prevent accidental disconnections and/or
avoid compromising the IP65 environmental protection rating.
Commissioning is carried out via Wi-Fi connection to the inverter web user inteface. Initial setup must therefore be carried out via a tablet, notebook or smartphone
with a Wi-Fi connection.
To establish the connection and operate with the inverter, it is necessary to connect its input to the DC voltage of the photovoltaic panels.
•Supply the inverter with DC input voltage from the photovoltaic generator and via AC GRID voltage.
Make sure that the irradiation is stable and adequate for the inverter commissioning procedure to be completed.
• Pre-commissionig phase 1 - Connection to the local Wi-Fi network
- DEVICE USED TABLET/SMARTPHONE.
Once powered, launch a QR reader for mobile and SCAN the QR code marked with on the label on the right side of the inverter and connect to inverter
network (tap connect).
The name of the Wi-Fi network created by the system, that the connection should be established with, will be:
ABB-XX-XX-XX-XX-XX-XX (where the X is the MAC address)
After this step wait 10 seconds to allow the WLAN connection
- DEVICE USED LAPTOP.
Enable the wireless on the device you are using for the commissioning and search for the network named ABB-XX-XX-XX-XX-
XX-XX, where “X” is an hexadecimal number of the MAC Address (the MAC Address is indicated on the “wireless identication
label” on the side of the inverter).
