Installation Instructions
The panel is connected to the wall with 3 screws.
The cable entries are located above the main PCB and can be introduced
from the rear with flush panel mounting, or from above with surface panel
mounting. If the cables are routed to the panel as flush mounted cables, the
cover panel should be fixed in the upper mounting position so that the cable
entry is covered off. With surface mounting, the cover panel should be
mounted in the lower position. The width of the metal panel is dimensioned
to ensure that the PCB is still externally inaccessible. Strain relief is provided
in both cases using a cable tie that can be introduced horizontally or
vertically into the cover panel.
To ensure optimum EMC immunity, the screens of the incoming cables
(detector circuits, XIB bus cables, ...) must be connected using the shortest
possible path to the earthing stud beside the cable entry.
The strain relief is located directly before the 230 V terminal block with
integrated fuse. As it is a device with a metal enclosure (protection class 1),
the protective earth (PE) must be connected.
