9.1 Ambient conditions
Icing, condensation and dew in and on the unit are
not permitted.
Avoid direct sunlight or radiation from red-hot surfaces
on the unit. Note the maximum medium and ambient
temperatures!
Avoid corrosive influences, e.g. salty ambient air or SO
2
.
The unit may only be stored/installed in enclosed
rooms/buildings.
The unit is suitable for a maximum installation height
of 2000 m AMSL.
Ambient temperature: -20 to +50°C (-4 to +122°F),
no condensation permitted.
Long-term use in the upper ambient temperature
range accelerates the ageing of the elastomer ma-
terials and reduces the service life (please contact
manufacturer).
Storage temperature = transport temperature: -20
to +40°C (-4 to +104°F).
Enclosure: IP 65.
This unit is not suitable for cleaning with a high-pressure
cleaner and/or cleaning products.
