Other standards Among other things, the following standards shall be observed in their
current version for proper installation:
• IEC/EN 60079-14: "Explosive atmospheres - Part 14: Electrical
installations design, selection and erection"
• EN 1127-1: "Explosive atmospheres - Explosion prevention and
protection - Part 1: Basic concepts and methodology"
Extended
order code
The extended order code is indicated on the nameplate, which is affixed
to the device in such a way that it is clearly visible. Additional
information about the nameplate is provided in the associated
Operating Instructions.

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.

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.
• 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
• Comply with the installation and safety instructions in the Operating
Instructions.
• Install the device according to the manufacturer's instructions and
national regulations.
• 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)
Safety
instructions:
Special conditions
• In the case of process connections made of polymeric material or with
polymeric coatings, avoid electrostatic charging of the plastic
surfaces.
• In the event of additional or alternative special varnishing on the
enclosure or other metal parts:
• Observe the danger of electrostatic charging and discharge.
• Do not rub surfaces with a dry cloth.

• Do not open in a potentially explosive dust atmosphere.
• Seal the cable entry or piping tight (see protection type of enclosure
in the "Temperature tables" chapter).
• Connect the device using suitable cable and wire entries of protection
type "Equipment dust ignition protection by enclosure (Ex t)" or
"Increased safety (Ex e)" (ingress protection of at least IP65).
Lay connecting cable and secure.

Temperature
tables
• The specified surface temperature takes into account all direct
heat influences from process heat and self-heating at the
enclosure.
• Surface temperatures at the process side maybe higher and
must be considered by the user (e.g. at high temperature process
connections).
• The T-marking is based on the process temperature of the
compact designs.
• The specified ambient and process temperature ranges
exclusively refer to the explosion protection and must not be
exceeded. Operationally permitted ambient temperature ranges
can be restricted depending on the version: See Operating
Instructions.
• Do not exceed the max. ambient temperature at the enclosure.
Device type PMC51, PMP51
The process temperatures refer to the temperature at the
separation membrane.
Device type PMP55
Higher temperatures are permitted depending on the type of
diaphragm seal.

• The tightening torque refers to cable glands installed by the
manufacturer:
• Recommended: 3.5 Nm
• Maximum: 10 Nm
• This value may be different depending on the type of cable.
However, the maximum value must not be exceeded.
• Only suitable for fixed installation. The operator must pay attention
to a suitable strain relief of the cable.
• The cable glands are suitable for a low risk of mechanical danger
(4 Joule) and must be mounted in a protected position if larger
impact energy levels are expected.
• To maintain the ingress protection of the enclosure: Install the
enclosure cover, cable glands and blind plugs correctly.
