DANGER
The inlet must be arranged so that no foreign
elements are sucked in and ejected through the
outlet. (hazard for eyes and skins)
When air is sucked in from the atmosphere, the inlet
must be covered with protective devices (i.e. gratings)
in order to prevent foreign elements including parts of
the body and clothing being sucked in.
Covers which prevent contact with active or rotating
parts are not to be opened during operation.
