• 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 first cartridge in the right from the AC discharger.
• Reinstall the cover of the AC wiring box cover using the 8 fixing 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 Configuration> 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
configuration 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 configurations for the proper
functioning of the system.
• Download the Aurora Manager LITE software, which allows to do the inverter configurations 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 fixing screws
(tightening torque 2.4Nm).
• Place the DC disconnect switch to position ON.
