6.5.2 Setting the Country Standard and Language using the
Rotary Switches
1. Disconnect the inverter and open it (see Section 8.2 "Disconnecting the Inverter from Voltage
Sources" (page 57)).
2. Set the arrows on both rotary switches (A and B) to
the required positions with a screwdriver (see table
in Section 6.5.1 "Checking the Country Standard"
(page 45)). Use a screwdriver with blade width
2.5 mm.
3. Close the inverter (see Section 8.3 "Closing the Inverter" (page 60)).
DANGER!
Danger to life due to high voltages in the event of electricity grid failure
If you set the inverter to stand-alone grid operation "Off-Grid 50 Hz"/"Off-Grid 60 Hz",
you are not allowed to operate the inverter on the electricity grid, but only on the stand-
alone grid, because the inverter does not satisfy any country-specific standards and
guidelines in this setting. In the event of electricity grid failure, this will prevent the danger
of backfeed.
• If the inverter is set to "Off-Grid 50 Hz" or "Off-Grid 60 Hz", never operate the
inverter directly on the electricity grid.
Temporarily setting the display language
to English
In addition, it is possible to use a switch to set
the display language to English temporarily,
e.g. for service purposes. This will have no
effect on the inverter parameter settings.
• Push the left switch 1 up until it locks into
place. Use an object with a small tip, e.g.
a ballpoint pen to do this.
• To reset the display language to the
original language, push the left switch 1
back down until it locks into place.
