General warnings • Compliance with national regulations relating to the installation, connection to the electricity supply,
commissioning and maintenance of devices in potentially explosive atmospheres is mandatory, if such
regulations exist (e.g. EN/IEC 60079-14).
• Installation, connection to the electricity supply, commissioning and maintenance of the devices must be
carried out by qualified specialists trained to work on Ex-rated devices.
• Compliance with all of the technical data of the device (see nameplate) is mandatory.
• Open the device only when it is de-energized (and after a delay of at least 10 minutes following shutdown
of the power supply) or in an area free of explosive atmospheres.
• It is not permissible to connect the service adapter whilst the atmosphere is considered to be explosive.
• Opening the transmitter housing and the connection housing of the remote version is only permitted for a
brief time. During this time, ensure that no dust or moisture enters the housing.
• To guarantee resistance to dust, the transmitter housing, the connection housing of the remote version and
the cable entries must be tightly sealed.
• Use of the devices is restricted to mediums against which the process-wetted materials are adequately
resistant.
• The suitability of the device in the event of simultaneous occurrence of gas-air and dust-air mixtures
requires an additional assessment.
Special conditions The device must be integrated into the potential equalization system. Potential must be equalized along
the intrinsically safe sensor circuits.

Special conditions for Zone 0:
If Category II1G devices are necessary when installing the measuring device, make sure that sources of ignition
resulting from impact or friction between the housing and an iron or steel object cannot be created, even for
operational faults or malfunctions that seldom occur.
Installation instructions • For terminals No. 20 to No. 27 of the transmitter, only devices with ratings U
m

260 V and I
m

500 mA
are allowed to be connected (does not apply to intrinsically safe circuits).
• 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:

• The following applies when connecting the electronics housing in Ex d:
Only separately certified cable and pipe entries (Ex d IIC) must be used, which are suitable for an operating
temperature of up to 80 °C and for an ingress protection of IP 67. When using pipe entries, the associated
sealing equipment must be fitted directly at the housing.
• The following applies when connecting the electronics housing in Ex e:
Only separately certified cable and pipe entries, drain plugs (Ex e II) must be used, which are suitable for
an operating temperature of up to 80 °C and for an ingress protection of IP 67. The cables must be installed
such that they are fixed in place. Adequate strain relief must be ensured.
• Suitable cables and suitable, certified cable glands, cable entries and drain plugs must be used for measuring
devices operated at temperatures below –20 °C.
• The cable entries and openings not used must be sealed tight with suitable components.
• Turning the local display:
the screw cap has to be removed before the local display can be turned, and this must be done with the
device de-energized (and after a delay of at least 10 minutes following shutdown of the power supply).
• If Category "ia" intrinsically safe circuits of the measuring device are connected to certified intrinsically safe
Category "ib" circuits with explosion group IIC or IIB ratings, the type of protection changes to Ex ib IIC or
Ex ib IIB, as applicable. Intrinsically safe "ib" circuits are suitable for areas which require Category 2
equipment.
