instructions:
Installation
In the event of potentially explosive vapor/air mixtures, only operate
the device under atmospheric conditions.
• Temperature: –20 to +60 °C
• Pressure: 80 to 110 kPa (0.8 to 1.1 bar)
• Air with normal oxygen content, usually 21 % (V/V)
If no potentially explosive mixtures are present, or if additional
protective measures have been taken according to EN 1127-1, the
device may also be operated under non-atmospheric conditions in
accordance with the manufacturer's specifications.
• Continuous service temperature of the connecting cable:
–40 to +80 °C (–50 to +80 °C for optional specifications, ID Jx (Test,
Certificate) = JN); in accordance with the range of service
temperature taking into account additional influences of the process
conditions (T
a,min
and T
a,max
+ 20 K).
• Only use certified cable entries suitable for the application. Observe
selection criteria as per IEC/EN 60079-14. Accordingly, the
connection terminal does not include any ignition sources.
• When the measuring device is connected, attention must be paid to
explosion protection at the transmitter →  17.
• In potentially explosive atmospheres:
– Do not disconnect the electrical connection of the power supply
circuit when energized.
– Do not open the connection compartment cover when energized.
• When connecting through a conduit entry approved for this purpose,
mount the associated sealing unit directly at the housing.
• Seal unused entry glands with approved sealing plugs that correspond
to the type of protection. The plastic transport sealing plug does not
meet this requirement and must therefore be replaced during
installation.
• Only use certified sealing plugs. The metal sealing plugs supplied
meet this requirement.
Intrinsic safety
• The device can be connected to the Hauser FXA291 service
tool: refer to the Operating Instructions.
• The device can be connected to the remote display FHX50 which has
Ex ia explosion protection: refer to the Special documentation and Ex
documentation.
Potential equalization
• Integrate the device into the local potential equalization →  17.
• If the ground connection has been established via the pipe as
specified, it is also possible to integrate the sensor into the potential
equalization system via the pipe.
