ommissioning (Using the inverter display)
Do not place objects of any kind on the inverter during operation! Do not touch the heat sink
while the inverter is operating! Some parts may be very hot and could cause burns.
Before proceeding with commissioning, make sure you have carried out all the checks and
verifications indicated in the section on preliminary checks.

For the list of available grid standards and the relative details, contact ABB Technical Sales
(1-877-261-1374) .
From the moment that the grid standard is set, you have 24 hours to make any changes to
the value, after which the "Settings > 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 remaining
time for grid standard variation" described in the relevant section).

The procedure for commissioning the inverter consists of the following
steps:
• Close the DC disconnect switch to supply the inverter with the photovol-
taic generator voltage.
If the inverter is equipped with a DC disconnect switch, set the DC dis-
connect switch
• When the inverter is connected to the power supply, the display will
show a guided configuration procedure and the yellow ALARM led is fast
blinking. Press ENTER to set the following:
- Inverter date and time
- Selection of the current input mode: Independent or Parallel (See the
relevant section of this manual to know how to set the proper input mode)
- Selection of grid standard and corresponding display language.
• After having set the Country Standard (grid standard), the message "Ini-
tializing...Please Wait" is displayed. Regardless of the input voltage value,
the inverter displays various messages and changes the behaviour of the
"Power" and "Alarm" LEDs

Description
The input voltage is not sufficient to enable connection
to the grid.
The input voltage is sufficient to enable connection to the
grid: the inverter waits for the grid voltage to be present
to make the parallel connection.
