3 Mounting
3.1 Operating conditions
Differential pressure can be measured in dry, non-ionizing
and aggressive gases with this measuring instrument.
It should not be installed near to sources of interference
(transformers, signal sources, electric motors) or sources of
heat.
Tremors or vibrations at the mounting location can lead to
measurement errors.
The instrument was adjusted at an ambient temperature of
20°C, vertically, with the process connection pointing down.
Any variation of this mounting position and ambient
temperature can cause measurement errors.

4 Electrical connection
Only suitable qualified professionals are allowed to
connect the pressure transmitters!
Please comply with the regulations and safety
requirements for electrical, weak current and power
current installations, particularly taking into account
pertinent national regulations, such as VDE 0100.
The supply voltage must not be connected to
output signal terminals! This would result in an
instrument fault.
