spections, any intervention in the terminal area always has to be performed by a
qualified technician (see safety instructions in chapter 1.3)!
If any incoming cables are damaged the Sunny Island has to be disconnected from
all power supply units. The failures then have to be repaired by a qualified electri-
cian.
Enclosure
Check the enclosure of the Sunny Island for mechanical integrity. Should there be
any damages reducing the Sunny Island’s operating safety (cracks, holes, fissures,
missing covers) the Sunny Island has to be decommissioned immediately!
Large dirt particles should be removed from the device with a soft hand brush or a
similar tool. Fine dust can be wiped off the enclosure parts with a soft moistened
cloth. Cleaning agents containing solvents or abrasives should not be used to avoid
scratching the paint layer.
The Sunny Island has lateral ventilation grates. These should be kept clear of dust
and other deposits to ensure reliable and powerful operation. These grates can be
best cleaned with soft brushes. During cleaning make sure to keep dust from enter-
ing the inverter. Cleaning intervals depend on local conditions as well as the operat-
ing mode of the Sunny Island and are to be determined in an inspection which first
should be made every three months.
User interface, display
The user interface can best be cleaned with a soft moistened cloth. Cleaning agents
containing solvents or abrasives may not be used!
