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