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.
