WARNING
Danger to life due to loss of explosion protection from damaged process connection
The diaphragm of the ush process connection is a safety-relevant component. If it is damaged, the
explosion protection is no longer guaranteed. Through any explosion resulting from this, there will be a
high danger to life.
▶
Before commissioning the pressure transmitter, the diaphragm of the ush process connection
should be checked for visible damage.
▶
Leaking uid is indicative of a damaged diaphragm.
▶
Protect the diaphragm from contact with abrasive media and against any impacts.
▶
Observe the specications for the use of the pressure measuring instrument in combination with
aggressive/corrosive media and for avoiding mechanical hazards.
▶
Only use the pressure transmitter if it is in perfect condition with respect to safety.
WARNING
Danger to life through improper mounting
Improper installation can lead to the loss of the explosion protection and to life-threatening situations.
▶
Adhere to the permissible ambient and medium temperatures which are valid for this area on
the basis of the specied temperature classes. (→ see chapter 3.8 “Special conditions of use
(X conditions)” and chapter 9 “Datos técnicos”).
