• 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 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 17.
• Use of devices in zones according to the category:

• For operation in Cat. II3G, make sure that the maximum operating voltage stated on the nameplate is not
exceeded by more than 40% as a result of temporary interference
• Before switching on the equipment, make sure that the connection data are within the max. permissible
connection values stated on the nameplate.
• The manufacturer's specifications for all devices connected to the intrinsically safe circuits must be taken
into consideration.
• 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 16.
• 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 to +10 °C above the ambient temperature present (–40 °C to (T
• All equipment of the measuring system must be included in potential matching (see Page 17).
• The service connector may not be connected in a potentially explosive atmosphere.
• The devices may only be used for fluids against which the wetted materials are sufficiently resistant.
General
The system meets the basic safety and health requirements for the design and construction of devices and
protection systems designated for use in hazardous areas in accordance with Annex II of Directive 94/9/EC.
Identification
The system identification must contain the following information:
Prosonic Flow 92F**-*****H*****A
Prosonic Flow 92F**-*****H*****W
Prosonic Flow 92F**-*****H*****H
Prosonic Flow 92F**-*****H*****K
"
Caution!
The installation instructions for the safe use and application of the system must be observed (see Page 14).
The measuring system consists of a transmitter and a sensor. Two versions are available:
• Compact version:
The transmitter and sensor form a mechanical unit.
• Remote version:
The transmitter and sensor are mounted separate from one another and interconnected by means of a
connecting cable (see also "Electrical connections" ( Page 17)).
