Operation Manual
Accepting the settings
Saving the made settings is indicated by an hourglass symbol on the user interface. If the DC
voltage is sufficient, the data is transferred directly to the inverter and accepted. If the DC
voltage is too low (e.g. in the evening), the settings are saved, but they cannot be directly
transferred to or accepted by the inverter. As long as the inverter has not yet received and
accepted the settings, the hourglass symbol will continue to be displayed on the user interface.
The settings will be accepted when there is sufficient DC voltage applied and the inverter
restarts. As soon as the hourglass symbol appears on the user interface, the settings have been
saved. The settings will not be lost. You can log off of the user interface and leave the system.
6.2 Configuring the Country Data Set
As standard, the inverter is meant for connection to a utility grid with a 208V wye connection or a
240V split-phase system, and the associated country data set UL1741/2010/120 is factory-set.
If the default country data set does not correspond with the grid configuration, the country data set
can be adapted to the connected grid configuration.
The basic procedure for changing operating parameters is explained in another section (see
Section6.1 "Changing Operating Parameters", page30).
Grid configuration Country data set
208Vdelta connection UL1741/2010/208

240 V delta connection UL1741/2010/240
240V split-phase system UL1741/2010/120
Procedure:
• Select the parameter Set country standard and set the required country data set.
6.3 Deactivating the Arc-Fault Circuit Interrupter (AFCI)
The basic procedure for changing operating parameters is explained in another section (see
Section6.1 "Changing Operating Parameters", page30).
Procedure:
• Select the parameter AFCI switched on or AfciIsOn and set to No.
