3.3.2.4 Wiring of cavity equipment rack
The wiring between the cavity equipment rack and the equipment rack of the
DIB-500 R4.1 is identical in all variants and, for this reason, is done independently of
the installed cavity couplers and the frequency used.
Figure 3.30 shows the wiring of the cavity equipment rack to the equipment rack of the
DIB-500 R4.1 with four carriers in a schematic representation. The following table
describes these indicators in detail. Upon delivery, the connections have already been
wired ex works.
