Important information

!

·The direct PV generator voltage is availa- ble internally after connecting the PV generator to the solar inverter via the DC connectors and switching on the PV generator switch!

·Please note that the input capacitors are still charged even after switching off the PV generator switch or removing the PV generator plug connection!

·After disconnecting the AC and DC side, the solar inverter still conducts voltage for up to ca. five minutes!

·Therefore, wait for at least five minutes until the internal voltage has dissipated. Then you can work on the terminals!

Please note the general safety informa- tion on pages 83 and 84!
