The device is designed for operation in explosive gas or explosive dust
atmosphere as shown in the sketch above. In the event of potentially
explosive gas-air and dust-air mixtures occurring simultaneously:
Suitability requires further assessment.
A sequential change between gas and dust explosion protection is
only possible if:
• A period with non-explosive atmosphere is realized during the
transition or
• Special examinations are done which are not covered by the
certificate

At this position, an option (number or letter) selected from the
specification is displayed instead of the placeholders.
Basic specifications
The features that are absolutely essential for the device (mandatory
features) are specified in the basic specifications. The number of
positions depends on the number of features available.
The selected option of a feature can consist of several positions.
Optional specifications
The optional specifications describe additional features for the device
(optional features). The number of positions depends on the number of
features available. The features have a 2-digit structure to aid
identification (e.g. JA). The first digit (ID) stands for the feature group
and consists of a number or a letter (e.g. J = Test, Certificate). The
second digit constitutes the value that stands for the feature within the
group (e.g. A = 3.1 material (wetted parts), inspection certificate).
More detailed information about the device is provided in the following
tables. These tables describe the individual positions and IDs in the
extended order code which are relevant to hazardous locations.
Extended order code: Liquiphant
The following specifications reproduce an extract from the product
structure and are used to assign:
• This documentation to the device (using the extended order
code on the nameplate).
• The device options cited in the document.

Safety
instructions:
General
• The device is intended to be used in explosive atmospheres as defined
in the scope of IEC 60079-0 or equivalent national standards. If no
potentially explosive atmospheres are present or if additional
protective measures have been taken: The device may be operated
according to the manufacturer's specifications.
• Devices suitable for zone separation (marked Ga/Gb or Da/Db) are
always suitable for installation in the less critical zone (Gb or Db).
Due to space limitations the corresponding marking maybe not
indicated on the nameplate.
• Staff must meet the following conditions for mounting, electrical
installation, commissioning and maintenance of the device:
• Be suitably qualified for their role and the tasks they perform
• Be trained in explosion protection
• Be familiar with national regulations
• Install the device according to the manufacturer's instructions and
national regulations.
• Do not operate the device outside the specified electrical, thermal and
mechanical parameters.
• Only use the device in media to which the wetted materials have
sufficient durability.
• Avoid electrostatic charging:
• Of plastic surfaces (e.g. enclosure, sensor element, special
varnishing, attached additional plates, ..)
• Of isolated capacities (e.g. isolated metallic plates)
• Refer to the temperature tables for the relationship between the
permitted ambient temperature for the sensor and/or transmitter,
depending on the range of application and the temperature class.
• Alterations to the device can affect the explosion protection and must
be carried out by staff authorized to perform such work by
Endress+Hauser.
