8 Recommissioning the Inverter
9. Turn the DC load-break switch of the inverter to
position I.
10. If a distribution board (DC combiner) with integrated load-break switch is installed, switch on
the DC power supply via the DC load-break switch in the distribution board.
11. If a distribution board without a load-break switch (fuse only) is installed, restore the DC
power supply as follows: Wait until sunset and insert the DC fuses. The system must not be
under load.
12. Check whether the current settings of the inverter correspond to the settings before the
assembly had been replaced. If the settings have been reset due to replacing the assembly,
adjust the settings to the parameters before the assemblies had been replaced (see inverter
manual).
13. Ensure that the inverter feeds in correctly.
