Before turning on the device, make sure the installation is complete, with no defects visible.
The device may only be used within the limitations specified in the technical specifications.
The electrical connection of the device must be carried out in a way that the IP20 ingress protection is always ensured!
Ex ia certified transmitters may only be operated in certified and approved intrinsically safe Ex ia IIC circuits complying with the technical data and the device’s
explosion protection marking.
Attention! The devices may partially contain static charging capable plastic components. The presence of electrostatic charges may cause a risk of spark
generation and ignition and therefore electrostatic charges must be completely prevented!
Avoid friction on plastic surfaces!
Do not clean the device dry!
For example, use a wet duster!
Use exclusively Ex d IIC cable entry for devices with Ex d flameproof protection!
For Ex d models, the cover must be secured against opening after the cover is closed by a safety locking screw!
With 1/2 Ex marking device, the sensor membrane also serves as a partition between the Ex zones, therefore it must be protected against mechanical damage.
The aluminum content of the die-cast aluminum alloy case exceeds the limit, which requires the device must be protected against any possible sources of spark
or ignition resulted by impact or friction effects in an Ex environment.
The metal housing of the device must be connected to the EP (equipotential) network!

drcbr44a0600p_02 10 / 20
4. INSTALLATION
To enable the safe replacement of the instrument during operation the use of closing armature is recommended. A simple ball valve will be suitable for lower pressures
and for higher pressures (above 6 bar) a three-way blow-off needle-valve can be suggested.
In case of level measurement, it is advisable to screw the transmitter to the stump on the side of the tank.
Remove the packaging and protective cap just before the beginning of the assembly to avoid the damage of the diaphragm. Keep the protective cap!
In case if the installing of the unit is not immediate, the protective cap must be reinstated as soon as possible!
Treat any unprotected diaphragm with utmost care; as this part can be damaged very easily.
The device can be installed in-, or outdoors. Select the mounting position such that there is enough space for installation, programming and reading of the display.
Do not expose the device to direct sunlight when using outdoors! If you do so, direct solar radiation might cause that the permissible operating temperature of the
device would be exceeded. This is to be particularly avoided in case if the device is used in any explosion-hazardous area!
Select the operating position, so that splashed and condensed water can be drained off. Stationary liquid on sealing surfaces must be avoided! If the device has cable
outlet, the outgoing cable must be routed downwards. If the cable needed to be routed upwards, this must be done in an initially downward curve.
4.1 INSTALLATION INSTRUCTION
The measured medium – depending on its type and properties, might be hazardous to the installer. Therefore, the wear of appropriate protective clothing, gloves, and
goggles are recommended.
Torque should only be transferred to the hexagonal screw on the instrument body (torque wrench).
For the sake of noise suppression, the transmitter housing is grounded. If the grounding of the process is correct no further grounding is needed, otherwise the
instrument should be grounded.
Install the device only in depressurized and disconnected state!
Do not install the device where there is any risk of explosion. Do not open or configure the device in explosive area under normal operating conditions! For this reason,
it is recommended that the display and operating module is positioned at the same time as the mechanical installation. An important feature of the NIPRESS D-B00
family, that the individual functions can be set with the help of three miniatures, or the magnetic switches located under the metal cap. This has the advantage that the
device can be configured with the magnetic switches without opening the chambers. Right after configuration, the metal cap has to be reinstated and tightened
again, by hand!
Ensure that moisture cannot enter the device! The seals and sealing surfaces must not get dirty, as (depending on application and location) foulings might cause a
reduced degree of protection and conclusively might even lead to device failure or an irreparable damage of the device.
Positioning the display
The display and the operating module can be rotated continuously, to guarantee easy readability even in unusual mounting positions. The module is equipped with a
turning limiter which allows the part to be rotated by 315°.

drcbr44a0600p_02 11 / 20
Installation steps:
Tightening torques:
½" BSP: max. 10 Nm;
1" BSP: max. 20 Nm;
1½" BSP: max. 25 Nm;
½" NPT: max. 70 Nm.
The specified tightening torques must not be exceeded!
Do not use a pipe wrench, to avoid damaging the device!
Installation steps for BSP process connection (DIN 3852):
Do not use any additional sealing material such as Teflon tape!
Check if the O-ring is intact, its surface even and clean and seat in the designated groove accurately.
Screw the device into the correct thread by hand! If your device is to be secured with a knurled ring instead of a hexagon head screw, the pressure transmitter should
only be tightened by hand! Devices with hexagon head screw mounting must be tightened using a suitable open-end wrench (torque wrench)!
Installation steps for NPT process connection:
Use suitable seal (e. g. a PTFE-strip)! Screw the device into the correct thread by hand, and tighten it with a wrench!
Installation steps for flange connections:
Use a suitable sealant! Position the seal between the flange of the device and the flange of the process connection! Then attach the device to the process flange using
4 or 8 bolts/nuts (depending on flange design)!

drcbr44a0600p_02 12 / 20
5. WIRING
In order to electrically connect the device with the connection terminals, the cover
must be screwed off.
Use a shielded and twisted multicore cable for the electrical connection.
Electrically connect the device with connection terminals, then reinstate the cover
by hand and make sure that the housing is tightly closed again.
For devices with flameproof housing, a M20x1.5 cable gland HSK-M-Ex-d / Metr.
is prescribed; which is already pre-mounted.
Technical data of Ex d cable gland:
cable diameter: Ø10 – Ø14 mm (Ø0.39 – Ø0.55 inch);
width across flats: 24 mm (0.95 inch);
continuous operating temperature: -60 °C ... +105 °C (-76 °F … +221 °F);
certificate: xII 2G Ex db IIC Gb.
The D-B00 device family can be ordered with two different housing. The wiring of
the die-cast aluminum housing can be connected from the solid side, while the unit
can be parameterized using the display and keys from the other side where there
is a window.
For devices with cable gland, make sure that the external diameter of the cable
used is within the allowed clamping range! Once connected the wires, tighten
the gland screw firmly until the sealing is proper!
The bending radiuses of the cables have to comply with the following:
Cable without ventilation tube:
-static installation: 8-fold cable diameter,
-dynamic application: 12-fold cable diameter.
Cable with ventilation tube:
-static installation: 10-fold cable diameter,
-dynamic application: 20-fold cable diameter

The measured values are shown and the configuration of the individual parameters is
made in a displayed menu. The individual functions can be set by three miniature keys,
or the magnetic switches located under the metal cap. The configuration of the device
using the magnetic switches is particularly advantageous, as doesn’t require the opening
of the chambers. Use a suitable bar magnet or a stronger magnetic screwdriver for this
purpose, that fits into the socket. If required, a special screwdriver is available, with an
end designed as a screwdriver and the other is as a bar magnet. Furthermore, a bar
graph is shown in the display, indicating the current pressure input as percentage of the
specified pressure range. The menu system is a closed one, which can be customized
also, allowing you to scroll both forward and backward until the desired setting item.
All settings are permanently stored in a Flash EPROM and therefore available again even
after disconnecting the device from the supply voltage.
