Potentially fatal voltages are present in the
inverter during operation. When the inverter
is disconnected from all power sources, this
voltage remains in the inverter for up to 60
seconds.
► Perform the instructions listed in "10.4 Mak-
ing preparations for maintenance work - dis-
connecting the inverter from the grid (AC)
and solar modules (DC)", page 115before
you start work on the inverter!
Do not use any sharp, pointed or hard objects
for cleaning.
Do not use liquids for cleaning.
The screws are very small and can easily fall
down. You should therefore use a magnetic
screwdriver.
