If the couplings are used in locations subject to dust explosion and in mining the user must
make sure that there is no accumulation of dust in a dangerous volume between the cover
and the coupling. The coupling must not operate in an accumulation of dust.
For covers with unlocked openings on the top face no light metals must be used if the
couplings are used as equipment of equipment group ll (if possible, from stainless steel).
If the couplings are used in mining (equipment group l M2), the cover must not be made of
light metal. In addition, it must be resistant to higher mechanical loads than with use as
equipment of equipment group ll.
During operation of the coupling, please pay attention to
•
different operating noise
•
vibrations occurring.
!
If you note any irregularities with the coupling during operation, the drive unit must be
switched off immediately. The cause of the breakdown must be specified by means of the
table „Breakdowns“ and, if possible, be eliminated according to the proposals. The potential
breakdowns specified can be hints only. To find out the cause all operating factors and
machine components must be considered.
Coating of coupling:
If coated (priming, paintings, etc.) couplings are used in potentially explosive atmospheres,
the requirements on conductibility and coating thickness must be considered. With
paintings up to 200 µm electrostatic load does not have to be expected. Paintings and
coatings exceeding a thickness of 200 µm are generally impermissible for potentially
explosive atmospheres. It also applies for multiple coatings exceeding an overall thickness
of 200 µm. Make sure with painting or coating that the coupling components are
conductively connected with the device/devices to be connected so that the equipotential
bonding is not impeded by the paint or coat applied. In addition, make sure that the marking
of the coupling remains legible. Painting or coating of the sleeve is generally not admitted.
The below-mentioned failures can result in a use of the
BoWex

coupling other than intended. In addition to the
specifications given in these operating/assembly instructions make sure to avoid such failures.
The errors listed can only be clues to search for the failures. When searching for the failure the adjacent
components must generally be considered.
If used other than intended the coupling can become a source of ignition.
EU directive 2014/34/EU requires special care by the manufacturer and the user.
