Installation instructions

Endress+Hauser
• Any national regulations pertaining to the installation of devices in hazardous areas must be observed.
• Mounting, electrical installation, commissioning and maintenance of the devices may only be performed by
technical staff trained in the area of explosion protection.
• Compliance with all of the technical data of the device (see nameplate) is mandatory.
• The connection compartment of the transmitter housing may only be opened when the unit is de-energized
or if an explosive atmosphere is not present.
• The device must be integrated into the potential equalization system. Potential must be equalized along the
intrinsically safe sensor circuits. Further information can be found in the "Potential equalization" chapter on
Page 22.
• The connection compartment Prosonic Flow 92**-*****U/C/3****** may only be opened in a
Ex atmosphere when the device is de-energized (and after waiting 6 minutes after switching off the
power supply).
• Use of devices in zones according to the category:
Zone
0
II2(1)G 1
21
0
II1/2(1)G 1
21
• If the active intrinsically safe communication circuits are fed into areas that require 2G or zone 1 apparatus,
the connected apparatus must be tested and certified accordingly.
• In Zone 0, potentially explosive vapor/air mixtures may only occur under atmospheric conditions.
If no potentially explosive mixtures are present, or if additional protective measures have been taken
according to EN 1127-1, the devices may be operated under other atmospheric conditions in accordance
with the manufacturer's specifications.
• The cable entries and openings not used must be sealed tight with suitable components.
• The measuring device must only be used in the permitted temperature class.
The values of the individual temperature classes can be found in the temperature tables on Page 21.
• The manufacturer's specifications for all devices connected to the intrinsically safe circuits must be taken
into consideration.
• To rotate the transmitter housing, please follow the same procedure as for non-Ex versions.
The transmitter housing may also be rotated during operation.
• The continuous service temperature of the cable must correspond at least to the temperature range of
–40 °C and up to +10 °C above the ambient temperature present (–40 °C to (T
• The devices may only be used for fluids against which the wetted materials are sufficiently resistant.
• Only use cable entries that have separate certification (Ex d IIC) which are suitable for an operating
temperature up to 80 °C. When using conduit entries, the associated sealing facilities must be mounted
directly to the housing.
• The service connector may not be connected in a potentially explosive atmosphere.
