CAUTION
n The inverter must be installed in a location protected from rain and snow.
n When installing several inverters next to each other, you must observe a distance
of 0.5 metres between the inverters. This distance prevents the mutual thermal
inuence due to the hot exhaust air of the ventilation systems.
n The ventilation inlet and the ventilation outlet must never be covered. Free air
circulation is absolutely necessary to permit the inverter to function properly.
n The installation location must meet the requirements related to electromagnetic
emissions (EN 61000-6-4).
NOTE
n For easy installation of the DC and AC supply lines you should design a freely ac-
cessible area of approx. 0.5 metres in height below the inverter.
n Make sure there is sufcient ventilation if the inverter is installed inside a building
or plant room. Maximum useful life requires that the ambient temperature is never
higher than 30°C.
n Due to possible noise emissions, we do not recommend installation in or near resi-
dential rooms or workplaces.
n The ambient air should be dust-free to avoid excessive dirt on the heat sink and
fans. Rooms with heavy concentrations of dust (e.g. in cabinetmaking or metal
workshops, hay storage buildings) are not suitable installation locations.
4.3 Lightning protection
The requirements for appropriate lightning protection for a PV plant depend on many dif-
ferent factors (plant size, how the cables are run, the modules used, the surroundings,
etc.). A project-specic protection concept must be developed by a qualied person.
