3.1 General
The device is designed for installation onto assembly plates or flat walls. To this
end, a pre-mounted 35 mm plastic mounting rail is also supplied. The attach-
ment screws are not included in the delivery.
Alternatively, the device can also be mounted to a 35mm hat rail.

At the factory, the device is calibrated for vertical installation, but the installation
position is arbitrary. For any installation positions that are not vertical, the zero-
point signal can be corrected via the installed offset correction.
The enclosure protection type IP 65 is only guaranteed, if a suitable power sup-
ply cable is used (see accessories).
3.2 Mounting in explosive areas
• If operated in explosive areas, the valid local regulations and guidelines for
the installation and operation of electrical systems in explosive areas must
be observed.
• If units are used in potentially explosive areas, the personnel must receive
additional training or briefings or have a permit to work on explosion-protec-
ted units in potentially explosive systems.
DANGER! The operator must ensure that any falling objects cannot collide
with the installed unit.
Steps must be taken to prevent the impact creating sparks so that the protection
class of the casing is no longer guaranteed. This can be avoided by attaching
protective cover, a protective housing or similar.
3.3 Process connection
• By authorized and qualified specialized personnel only.
• The pipes need to be depressurized when the instrument is being connec-
ted.
• Appropriate steps must be taken to protect the device from pressure surges.
• Check that the device is suitable for the medium being measured.
• Maximum pressures must be observed (cf. Tech. data)
The pressure lines must be kept as short as possible and installed without any
tight bends to avoid delays.
The pressure lines must be installed at an inclination so that no water pockets
are created. If the required gradient is not reached, water filters need to be in-
stalled at suitable points.
The process connections are marked with (+) and (-) symbols on the device.
The pressure lines must be mounted according to these symbols.
