Opening the unit<br />
Before opening the cabinet, the unit must<br />
always be disconnected from the grid and<br />
from the PV generator.<br />
The unit continues to conduct a hazardous<br />
voltage internally and at the connection<br />
sockets for ca. five minutes after disconnecting<br />
from the PV generator. The energy<br />
storage capacitors are only fully discharged<br />
after this period.<br />
After disconnecting the unit from the grid<br />
and from the PV generator, you must wait<br />
at least five minutes before opening the<br />
unit.<br />
