1. Make sure that the mains voltage is within the permissible voltage range.
The exact operating range of the inverter is specified in the operating parameters. The
corresponding documents are available in the download area at www.SMA.de/en, in the
"Technical Description" category of the respective inverter.
2. Shut down the miniature circuit-breaker and secure it to prevent reactivation.
3. If an external DC switch-disconnector is in use, disconnect it.
4. If an ESS is in use, disconnect the ESS.
5. Loosen all six captive screws and remove the lower
enclosure lid. Use an Allen key (AF 3) to do this.
6. Check that the country setting of the inverter is correct using the supplementary sheet with the
default settings provided.
If the inverter is not set to the desired country standard, then adjust the country standard
(see Section 6.5.2 "Setting the Country Standard and Language using the Rotary Switches"
