Overview Both standard (non-Galvanically Isolated) and Galvanically Isolated FTAs are mounted on a vertically oriented FTA Mounting Channel in the cabinet. The vertical FTA Mounting Channel has two channels (troughs), right and left. When standard FTAs are mounted on the vertical FTA Mounting Channel, the FTA Mounting Channel is installed in its “normal” position where field wiring enters the left channel and connects to the FTAs. The cables connecting the FTAs to their associated IOP(s) or Power Distribution Assemblies are routed in the right channel of the FTA Mounting Channel. When Galvanically Isolated FTAs are mounted on the vertical FTA Mounting Channel, the FTA Mounting Channel is installed in its “inverted” position where field wiring enters the right channel and connects to the FTAs. The cables connecting the FTAs to their associated IOP(s) or Power Distribution Assemblies are routed in the left channel of the FTA Mounting Channel. Galvanically Isolated FTAs and standard FTAs must not be mounted on the same FTA Mounting Channel. FTA Mounting Channel configurations The vertical FTA Mounting Channel length, approximately 93 centimeters (36 inches) is approximately half the height of the cabinet. The FTA Mounting Channels can be mounted adjacent to each other in this vertical area. The FTA mounting configurations will allow • up to four narrow channels or • up to three wide channels. The FTA Mounting Channel configurations can be mounted adjacent to each other in the area.below the Power System in a single-access cabinet as shown in Figure 8-6. In the dual-access cabinet, one FTA Mounting Channel is normally installed above another, adjacently in pairs, as shown in Figure 8-7.
