Use of the ferrule cleaner (example)
In practice, the use of a ferrule cleaner provides good results. In the case of an
incomplete cleaning, this process should be repeated several times.
Alternatively, the cleaning with a cleaning cloth is possible following the partial
pulling out of the optical ports panel (see Chapter “Cleaning the internal fibre-
optical connectors with a cleaning cloth”).
Cleaning the internal fibre-optical connectors with a cleaning cloth
If a ferrule cleaner is not available or the cleaning with the ferrule cleaner has not
been successful, then the optical ports panel can be partially pulled out for cleaning
and inspection of the internal fibre-optical connectors just like a drawer. In this
case, cleaning with a suitable cloth is possible.
WARNING!
Switch the controller off before optical fibres, splice
connections or optical fibre connectors are inspected!
Additionally, sufficient measures must be taken to protect
against inadvertent reactivation.
Only the partial pulling out of the optical ports panel is required for the cleaning
of the internal fibre-optical connectors without a ferrule cleaner.
The opening of the controller housing via the housing cover is not required!
CAUTION!
Internal fibre-optical connectors that are damaged or do not work correctly after
repeated cleaning must be replaced by the manufacturer.
