about
construction
The branch interface module has the standard narrow Momentum housing.
A sliding label is delivered together with the branch interface module. It fits onto the
space on the front of the branch interface module.
Above and below the label tag there are ventilation slots to allow natural airflow for
cooling when mounted vertically.
In the slots underneath the labeling film there are LEDs for diagnostics, status and
operating elements (170 BNO 681 00).
