DANGER!
The pressure transmitter does not meet the "Equipment with safety function" requirements ac-
cording to the Pressure Equipment Directive 2014/68/EU.
 The current relevant regulations must be observed for dangerous media, e.g. oxygen, acetylene,
flammable, and poisonous substances, as well as for cooling systems and pressure tanks etc.
The national and international safety and accident prevention regulations must be observed!
Failure to observe these guidelines may result in bodily injuries and material damage!
The plant operator is responsible for compliance with the legal regulations!
Only suitably qualified persons are permitted to work at this device.
5.1 General information
Prior to mounting
DANGER!
Depressurize the plant prior to mounting the pressure transmitter!
CAUTION!
The pressure transmitter may only be used for media to which the membrane is sufficiently
chemically resistant (corrosion).
Ensure there is an electrically conductive connection between the pressure transmitter and the
process connection (plant).
NOTE!
Select a freely accessible and low-vibration installation location, preferably near the measuring point.
Ensure that the admissible ambient temperature is adhered to (take possible heat radiation into ac-
count).
The pressure transmitter can be installed above or below the pressure sensing point.
5.2 Pressure connection
Seals
DANGER!
A flat seal, e.g. according to DIN EN 837, must be used for the appropriate process connection
for the ignition protection type intrinsic safety!
 The pressure connection must be checked for seal tightness once established!
If the pressure transmitter is screwed into a threaded hole, the
full length of the thread of the pres-
sure transmitter must be used!
NOTE!
The correct tightening torque is dependent on the size, material, and form of the seal used, as well as
the pressure connection of the pressure transmitter.
