necessary to open the ventilation flap at the front. This flap can be opened during operation to do some hot-plug
operations.
Behind the ventilation flap on the upper front there are the fans located. These fans are
spinning very fast. When opening the flap they are no longer powered, nevertheless they
need some time to spin out. During this period they still have the ability to harm you. Do
not stick your fingers or objects into the fans!
Be very careful, when opening the flap! The fans are close to the screws you loosened
before. Do not stick your fingers into the OmniBus to open the flap!
After opening the flap, wait until the fans have stopped spinning before touching anything
at the front of the OmniBus!
When opening the ventilation flap of the Argus OmniBus, the ventilation fans will stop and
the cooling of the device is interrupted as long as the flap is open. Therefore the flap should
not be open longer than 5 minutes, to guarantee at all times sufficient cooling!
