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 to which this document relates to are WITHOUT ISOLATION TRANSFOR-
MER (transformer-less). This type involves the use of insulated photovoltaic panels (IEC61730
Class A Rating) and the need to maintain the photovoltaic generator floating with respect to earth:
no pole of the generator must be connected to earth.
For the string connections it is necessary to use the quick fit connectors (multicontact or weidmüller) located on the
bottom of the mechanic
17 18
.
The number of quick fit connectors changes based on the model of inverter.

connectors
- Crimp the Multicontact/Weidmüller MC4/WM4 quick fit connector counterparts (supplied) to the string cables or to
the cables wired to the DC disconnect switches (external)
- Connect all the strings included in the design of the system and always check the tightness of the connectors
- If some of the string inputs should not be used you must proceed to verify the presence of covers on DC input
connectors and then install them should they be absent: this operation is necessary for the tightness of the inverter
and to avoid damaging the free connector that could be used at a later date.

Load protection breaker (AC disconnect switch) and line cable sizing
To protect the AC connection line of the inverter, we recommend installing a device for protection against over current and leakage with the following characte-
ristics:
PVI-3.0-TL-OUTD
Type
Nominal Voltage
Nominal Current
Magnetic protection characteristic
Number of poles
Type of differential protection
Differential sensitivity
ABB declares that the ABB 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
Three-pole cable required. 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.

The values are calculated in nominal power conditions, taking into account:
1. a power loss of not more than 1% along the line.
2. copper cable, with HEPR rubber insulation, laid in free air

Warning! Before performing any of the operations described below, ensure the AC line downstream
the inverter has been correctly disconnected
- Remove the protective film located on the hole to be used for the AC cables
- Insert the M25 cable gland in the hole and secure it using the special M25 lock nut (supplied)
Warning! To ensure environmental protection IP65 it is necessary to fix the cable gland to the inverter
chassis with a minimum tightening torque of 7.5 Nm
- Strip 10 mm of sheathing from the AC grid connection cables
- Plug the AC line cable into the inverter, passing it through the previously installed cable gland
- Connect the protective earth (yellow-green) cable to the contact labelled with the
Warning! ABB inverters should be earthed (PE) via the terminal with the protective earth label
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 letter N
- Connect the phase cable to the terminal labelled with the letter L
Warning! The AC cables must be tightened on the terminal block with a minimum torque of 1.5 Nm
Once the connection to the terminal board
is complete, screw in the cable gland firmly (tightening torque 5.0Nm) and check the tightness.

ABB inverters are equipped with a graphic Display
, consisting of 2 lines of 16 characters each, which can be used to:
07
- Display the operating state of the inverter and the statistical data
- Display the service messages for the operator
- Display the alarm and fault messages for the operator
- Changing the settings of the inverter
During the normal operation of the inverter the display cycles through the GENERAL INFORMATION. This information relates to the input and output parame-
ters and the inverter identification parameters. By pressing ENTER it is possible to lock scrolling on a screen to be constantly displayed.

Each cable which must be connected to the connectors of the communication and control signals must pass through one of the two service cable glands
PVI-3.0/3.6-TL-OUTD-S
An M20 cable gland (that takes cables from 7 mm to 13 mm in diameter) and a gasket with two holes to insert into the cable gland which enables two separate
cables of a maximum diameter of 5 mm to be accommodated, are available.

Warning! To ensure environmental protection IP65 it is necessary to fix the cable glands to the inverter chassis with a minimum tightening

Connection to the RS485 communication line
The RS485 communication port is the inverter's communication port.
The ABB inverters use an RS485 HALF-DUPLEX communication line
made up of two transmission and reception cables (+T/R and –T/R) and a
communication reference cable (RTN): all three cables must be connected
in daisy-chain configuration. The chain connection can be made without
distinction by using the RJ45 connector couples

The inverter commissioning procedure is as follows:
- Switch the integrated switch
greater than the minimum starting voltage, the inverter will start up.
- When the inverter is turned on for the first time you will be asked to select the "Nation" of installation. This selection allows the inverter to automatically confi-
gure its parameters to ensure that compliance with local standards; the default language corresponding to the selected "Nation" will also be set.
max 16 mm²
Warning! After the grid standard was set you have 24 hours to make any changes to the grid standard value; 24 hours later the "Nation
Select." functionality will be blocked, and any subsequent changes can only be made using a password provided on request by ABB
10 ÷ 17 mm
- After you have set the "Nation" value, the message "Inizializing...Please Wait" is displayed. Depending on the input voltage value, the inverter will show
various messages on the display and change the behaviour of the three LED
INPUT VOLTAGE
10
Vin < Vstart
Vin > Vstart
The inverter is powered ONLY by the voltage coming from the photovoltaic generator: presence of grid voltage alone IS NOT SUFFICIENT to permit
the inverter to start up.
- With the inverter in "Missing Grid" status, close the AC switch downstream the inverter so as to supply the grid voltage to the inverter: the inverter performs
the grid voltage check, measures the photovoltaic generator insulation resistance against earth and carries out other self-diagnosis checks. During the
checks before the parallel with the grid, the green LED keeps flashing, the others are off.
During the grid voltage check and measurement of the insulation resistance, the values for the grid voltage and frequency and the insulation resi-
stance measured by the inverter are shown on the display. The inverter completes parallel connection with the grid SOLELY if the grid parameters
meet the ranges provided for by the regulations in force and if the insulation resistance is greater than 1Mohm.
- If the preliminary checks for parallel connection to the grid are successful, the inverter connects to the grid and begins to export power to the grid. At this
stage, the display shows the inverter's parameters in cycles. The green LED stays lit whereas the others are off.

The input voltage is not sufficient to permit connection to the grid.
There is sufficient input voltage to permit connection to the grid:
the inverter waits until there is grid voltage to carry out the parallel
