○The operator must check critically
whether operation without a low-level
signal might lead to a new risk potential.
If this cannot be ascertained, provide a
low-level signal or suitable organisational
measures for monitoring of the bearing
point temperature.
○Avoid dust accumulation and remove
dust immediately. Dust accumulations
have a thermally insulating effect and, if
whirled up, generate the formation of a
potentially explosive atmosphere.
○The product must be integrated in the
operator's lightning protection concept.
○The product must be integrated in the
operator's switch-off concept for explo-
sion protected equipment in ATEX cat-
egory I M2.
○All parts are to be checked regularly for
corrosion. Replace the affected parts.
○Terminal boxes must be firmly closed and
the cable breakthroughs correctly sealed.
○Additional electrical monitoring devices
must be firmly connected and correctly
adjusted.

Gas: II 2G c IICTX; dust: II 2D c TX
Mining: I M2 C
The explosion protection marking is addi-
tionally found on the type identification plate.
1.24.1 ATEX marking TX
The surface temperature of the pump basi-
cally depends on the temperature of the hy-
draulic oil used. To determine the maximum
temperature occurring on the product, for
safety reasons, there should be considered
a temperature increase of 10 K compared to
the temperature of the hydraulic oil used.

1.25.1 Determination of hazards
The operator must determine all hazards re-
sulting from the integration of the pump into
the superordinate machine and the hazards
at the location of operation of the machine,
and carry out the measures necessary to
ensure safety and health protection.
1.25.2 Explosion protection measures
Due to a holistic assessment of the work-
place, the operator ensures that the working
equipment and all installation materials are
suitable for operation in potentially explosive
areas, and that they are assembled, installed
and operated so that they do not give rise to
explosions.
If changes, extension and/or redesigns are
undertaken in potentially explosive areas,
the operator must carry out the required
measures so that these changes, extensions
or redesigns fulfil the minimum regulations
for explosion protection.
The operator
○documents the measures for explosion
protection.
○marks the potentially explosive areas.
○prepares written operating instructions.
○selects suitable employees.
○provides the employees with sufficient
and appropriate instructions related to
explosion protection.
○applies an approval system for hazard-
ous activities and for those which may
become hazardous in interaction with
other work.
○carries out the necessary inspections and
monitoring.
○ensures that only original spare parts are
used.
1.25.3 Provision of necessary information
The operator must make the instructions
required for the respective activity accessible
to all people commissioned with operation,
maintenance and repairs.
He must ensure that these people have read
the necessary instructions and have under-
stood them.
The same applies for all relevant safety data
sheets, company instructions, accident pre-
vention regulations, instructions from sup-
pliers of purchase parts and utilities.
Depending on the business organization, the
relevant instructions may have to be made
accessible to other people and departments.
