WARNING!
Physical injuries and damage to property and the
environment caused by the back blowing out in the
event of a failure
Due to the high energy in the back, if it is blown out in the
event of a failure, there is a risk of physical injuries or damage
to property through the ejected back and the media that
would then escape.
It must be ensured that at no time can personnel or objects
▶
be at the rear of the instrument.

location has to be suitable for the specified ingress protection, so
that the pressure gauge is not exposed to impermissible weather
conditions.
In order to avoid any additional heating, the instruments must not be
„
exposed to direct solar irradiation while in operation!
To ensure that the pressure can be safely vented in the case of
„
failure, instruments with blow-out device or blow-out back must keep
a minimum distance of 20 mm from each object.
