Quick Installation Guide 1
Access to the zones inside the inverter must be carried out with the equipment dis-
connected from the network and from the photovoltaic generator.
Isolate the inverter by externally disconnecting the side AC, DC and any voltages
connected to the multifunction relay. Acting only on switches present on the inverter,
some internal parts have hazardous voltages.
The GROUNDING KIT must be installed inside the DC wiring box.
• Before removing the front cover, place the DC
disconnect switch to OFF position.
In “ON” position, the switch does not allow the
removal of the front cover.
• Proceed to remove the 8 screws holding the
front cover of the DC wiring box.
• The grounding board must be installed on the
appropriate holder positioned on the lower side
of the communication and control card (area
highlighted in the gure to the side).
• Press down lightly on both sides of the
board until the two holding clips will block
the board to the support.
• Connect the signals wiring between the
grounding board and the communication and
control board. One side of the signals wiring
must be connected to the J13 connector on
the grounding board; the other end must be
connected to J1 connector present on the
communication and control board.
• Connect the cable present on the grounding
board to negative pole placing the cable on
the negative connection of the DC disconnec-
tor switch (rst terminal at the top right of the
disconnector switch).
Observe the installation sequence shown in
the gure.
- Metallic support (tightening torque 4 Nm)
- Toothed washer
- Cable from the grounding board
- Cutted washer
- Hexagonal nut (tightening torque 4 Nm)
The components required for the xation of the cable are present in the materials supplied.
• Check the correct installation of the board,
signals wiring and connection cable to the
negative pole
In -SX version of the Wiring Box AC, a cartridge must be removed from the AC overvolt-
age dischargers (as described below)

TRIO-50.0/60.0-GROUNDING KIT
Grounding kit
Compatibility
Three-phase inverter models:
TRIO-50.0-TL
TRIO-60.0-TL
Type of grounding Resistive
Pole that can be connected to the earth Negative
System requirements
Isolating transformer Mandatory 1)
Conguration of the isolating transformer IT System
(Star point not connected to the earth)
Conguration of the photovoltaic strings
If the system has multiple inverters connected to the
same transformer, all strings must be made of the
same type and number of panels in series.
Maximum number of inverters that can be connected in parallel on a single winding of transformer:
Nominal power of the transformer 1000 kVA 1250 kVA 1600 kVA 2000 kVA 2500kVA
Maximum number of TRIO-50.0-TL 20 25 32 40 N.A.
Maximum number of TRIO-60.0-TL 17 21 27 33 40
1. NOT SUITABLE for mono- or multi-inverter systems that are directly connected to low voltage network.
Note: The features that are not specically mentioned in this data sheet are not included in the prod-
uct
• Before removing the front cover, place the AC disconnect switch to position OFF.
In position "ON", the switch does not allow the removal of the front cover.
• Proceed to remove the 8 screws holding the front cover of the AC wiring box.
• Remove the rst cartridge in the right from the AC discharger.
• Reinstall the cover of the AC wiring box cover using the 8 xing screws (tightening torque 2.4Nm).
•Selecting one of the inverters, the functions will be available in the working place related to the inverter.
•Access the “Setup” tab and then the section of “Ground fault interface”
In the section related to Grounding kit, enable the function by moving the selector to "protection ENABLED"
In this section, you can also customize (depending on the type of PV modules used) the maximum thresh-
old of the voltage between the negative pole and the earth, for which the inverter turn on the "protection of
Ground Fault" (E037)
• Open the Aurora Manager LITE software.
• Set the COM port, to which the converter is connected on the Communication>COM settings menu
• Access the advanced functions (INSTALLER) on the menu Conguration> Setup area access.
The personal information and password to be entered are the same as those used during the registration on
the website https://registration.abbsolarinverters.com/
After entering your personal data, press ENTER. Aurora Manager LITE will allow you to do the advanced
conguration of the inverter.
To get the password, register on the site https://registration.abbsolarinverters.com/, where, entering your
personal data, you will receive an email with your login credentials.
• Scan the RS485 bus using the "Refresh" button.
Once the scanning will be completed, the inverters detected are displayed in the system tree.
After installing the GROUNDING KIT, it is required to connect a PC to the inverter via a signal con-
verter PVI-USB-RS232_485 in order to perform the necessary software congurations for the proper
functioning of the system.
• Download the Aurora Manager LITE software, which allows to do the inverter congurations available on the
following website: http://new.abb.com/power-converters-inverters/solar/string/three-phase/trio-50-0kw in the
section Download > Software.
• Check the presence of the RS485 serial line, to which the signal converter PVI-USB-RS232_485 will be
connected. Otherwise, connect a signals wiring to the terminals of the J7 connector on the communication
and control board:
- J7 terminal 1 → -T/R serial line RS485-1
- J7 terminal 2 → +T/R serial line RS485-1
- J7 terminal 7 → -T/R serial line RS485-2
- J7 terminal 8 → +T/R serial line RS485-2
- J7 terminal 6 →RTN signal common to two serial lines
The cable must be passed inside the DC wiring box using the cable glands placed on the left side of the
external machine.
• Connect the serial wiring to the signal converter PVI-USB-RS232_485 following the connection of the sig-
nals performed on the communication and control board.
• Connect a USB cable (Type B) between the signal converter PVI-USB-
RS232_485 and PC
• Reinstall the cover of the DC wiring box cover using the 8 xing screws
(tightening torque 2.4Nm).
• Place the DC disconnect switch to position ON.
