2 General
2.1 Preface
Please read these Operating Instructions before commissioning the instrument.
Keep the instructions in a place which is accessible to all users at all times.
Please assist us to improve these operating instructions, where necessary.
Your suggestions will be welcome.
All the necessary settings are described in this manual. However, if
any difficulties should still arise during commissioning, you are
asked not to carry out any unauthorized manipulations on the unit.
You could endanger your rights under the instrument warranty!
Please contact the nearest subsidiary or the head office in such a
case.
When returning modules, assemblies or components, the
regulations to EN 100 015 “Protection of electrostatically sensitive
components” must be observed. Use only the appropriate ESD
packaging for transport.
Please note that we cannot accept any liability for damage caused
by ESD (electrostatic discharge).

2.2 Application
General note Pressure and differential pressure transmitters Type 404304 are used for mea-
suring very low pressures.
Corresponding to the measuring range, the CuBe diaphragm inside
the instrument is very sensitive.
Do not blow into the pressure connections, as this may
damage or destroy the instrument.
The instrument is suitable for non-corrosive gases only.
The instrument has no Ex approval.

4 Mounting
Fixing ✱Use the lugs to fix the instrument.
The instrument should preferably be fixed vertically (pressure
connections below), since it has been factory-calibrated in this posi-
tion.
This ensures that no condensate from the pressure lines will enter
the measuring system.
Do not install the instrument close to sources of interference (trans-
formers, transmitters, motors) or heat sources.
Shock or vibration will lead to measurement errors.

5.1 Electrical connection
Opening the
instrument
✱Unscrew the four slotted screws
✱Remove cover
Connection
When connecting the instrument, please observe the VDE regulati-
ons concerning work with mains supply voltage, as well as the
regulations of the trade insurance associations regarding work on
and with electrical equipment and installations.
Never connect the supply voltage to the output terminals!
For the required supply voltage, see nameplate.
Instruments with DC supply have a reverse polarity protection.
