General warnings
• 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.
Special conditions
• 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 7.
Installation instructions
• 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 6.
• The manufacturer's specifications for all devices connected to the intrinsically safe sensor circuit 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 °F and up to +18 °F above the ambient temperature present (–40 °F to (T
a
+18 °F)).
• All equipment of the measuring system must be included in potential matching (see Page 7).
• The devices may only be used for fluids against which the wetted materials are sufficiently resistant.
• The service connector may not be connected in a potentially explosive atmosphere.
• Install per National Electrical Code. Install intrinsically safe circuits per NEC ANSI/NFPA 70 and
ISA RP 12.6 respecting the explosionproof integrity of the enclosure.

Description of the
measuring system
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 7) and "Cable specifications for connecting cable"
(Page 7).
