Air Quality Classification
Should the required air quality at the installation site of the Sunny Central not be available,
corresponding requirements have to be made available (e.g. additional filters in the building supply
air bar) through construction measures.
The waste heat (exhaust air) produced by the inverter has to be led away from the device to observe
the maximum allowable ambient temperature and to ensure that the installation room is not
unnecessarily heated up by the warm exhaust air. This takes place through the installation of an
exhaust airflow (e.g. air channel).
Environmental requirements for fixed site use Class

Sites where dust fallout is kept to a minimum
through appropriate measures. x x x x
Sites where no special measures have been taken
to reduce the sand or dust levels and which are
far from sand and dust sources x x x
Sites near to sand and dust sources x x
Sites in production halls where sand or dust is
present, or sites in geographical locations in
which the air can contain high quantities of sand
and dust x
Ambient Conditions
The following points for environmental conditions have to be observed:
• amount of fresh air
• required air quality,
• relative humidity
• Allowable ambient temperatures
CAUTION!
Risk of crushing and bruising by metal parts.
Remove the finger protection from the fan openings of the Sunny Central before installing
the exhaust airflow.
