Where appropriate, the identifying mark of the expert
•
Transport damages may result in the loss of the explosion
protection. If transport damages can be seen, do not
assemble the product nor put it into operation.
•
All parts of the equipotential bonding / earthing concept must
be correctly available and connected with the superordinate
machine.
•
If transport lugs are dismantled after set-up, the threaded
bores must be permanently sealed in accordance with the
degree of protection.
•
Handle the materials so that no sparks generated by tilting,
falling, sliding, rubbing, impacting, etc. If needed, cover
materials with suitable means.
•
Never disconnect plug-in connections when energized.
Secure plug-in connections against inadvertent manual
disconnection with the safety clips included in the delivery.
•
The operator must check thoroughly whether an operation
without low-level signal leads to a new hazard potential (e.g.
through heat-up of bearing points on the machine in the area
of ignition temperature). 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.
•
All parts are to be checked for corrosion regularly. Replace
the affected parts.
•
Terminal boxes must be firmly closed and the cable ducts
correctly sealed.
•
Additional electrical monitoring devices must be firmly
connected and correctly adjusted.
1.18 Expiry of the ATEX approval
The ATEX certificate for this product expires through:
•
Use not in accordance with the intended purpose, e.g. in a
different, more critical potentially explosive atmosphere
•
Unauthorized modifications.
•
Use of non-original SKF spare parts / components.
•
Non-observance of these instructions and other applicable
documents.
•
Use of non-specified / unsuitable operating materials.
•
Operation with damaged or lacking ATEX painting or ATEX

•
Operation with damaged or lacking ATEX painting or ATEX
painting done wrongly later on
•
Non-observance of the permissible operating and ambient
conditions
•
Operation with damaged or lacking ATEX painting or ATEX
painting done wrongly later on.
•
Non-observance of the operator’s explosion protection
document.
1.19 Operation in explosion-protected
areas
Operation is permitted only, if in compliance with:
•
all information given in these instructions or stated in the
referenced documents.
•
all laws and regulations to be complied with by the user.
•
the information on explosion protection according to directive
1999/92/EC (ATEX 137).
1.20 Explosion protection marking
The explosion protection marking is found in the declaration of
conformity and on the type identification plate.
1.21 Inspections prior to delivery
The following inspections were carried out prior to delivery:
•
Safety and functional tests
•
In case of electrically driven products: electrical inspections
following EN 60204-1:2019-06; VDE 0113-1:2019-06
•
Inspections following the requirements of the ATEX Directive.
1.22 Briefing of external technicians
Prior to commencing the activities, external technicians must be
informed by the operator of the company safety provisions, the
applicable accident prevention regulations to be maintained,
and the functions of the superordinate machine and its
protective devices.
1.23 Provision of personal protective
equipment
The operator must provide suitable personal protective
equipment for the respective location of operation and the
purpose of operation. For work in potentially explosive
atmospheres this also includes ESD clothing and ESD tools.
1.24 Operator obligations
1.24.1 Determination of hazards
•
The operator must determine all hazards resulting 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.
