SPECIAL CONDITIONS FOR SAFE USE (X)
Because the enclosure of the Smart Pressure Transmit-
ter is made of aluminium, if it is mounted in an area
where the use of category 1 G apparatus is required, it
must be installed such, that, even in the event of rare
incidents, ignition sources due to impact and friction
sparks are excluded.
