2.14 FTA Mounting Channels
Introduction
FTA Mounting Channels are used to mount the Field Termination Assemblies (FTAs) and to organize
and separate the field wiring and IOP to FTA cables.
Location
The FTAs are installed on FTA Mounting Channels that are located in the front of a single access
High-Performance Process Manager cabinet, and in the rear or front of a dual access cabinet.
Number of FTA Mounting Channels
The number of FTA Mounting Channels that can be accommodated in an High-Performance Process
Manager cabinet is dependent upon whether the cabinet is single access or dual access, and whether
standard or wide vertically orientated FTA Mounting Channels are installed.
Optionally, horizontally oriented FTA Mounting Channels can be installed when Galvanically Isolated
FTAs are mounted in the cabinet.
Vertical FTA Mounting Channels
Vertical FTA Mounting Channels are available in two sizes, standard and wide, to better accommodate
the amount of process control wiring that connects to the FTAs. The FTA Mounting Channels provide
both a mounting surface for the FTAs and dual channels (troughs) to route the IOP to FTA cabling, and
the process control wiring.
When standard FTAs are mounted on the FTA Mounting Channel, the IOP to FTA or Power Distribution
Assembly cabling is routed in the right channel and the process control wiring is routed in the left
channel. The opposite is true when Galvanically Isolated FTAs are mounted on the FTA Mounting
Channel because the vertical orientation of the FTA Mounting Channel is reversed.
TIP
For EUCN, if you want to install the CF9 switch in an HPM cabinet, the top 24
inch of FTA tray must be cleared. The top six inches is left empty and the
carrier adapter assembly, which is used for mounting the CF9, occupies the
remaining 18 inches.
Horizontal FTA Mounting Channels
Horizontal FTA Mounting Channels can be installed when Galvanically Isolated FTAs are mounted in
the cabinet. Only Galvanically Isolated FTAs are mounted on the horizontal FTA Mounting Channels.
They are approximately 61 centimeters (24 inches) long and up to eight horizontal FTA Mounting
Channels can be accommodated on one side of the cabinet.
The IOP to FTA, Power Distribution Assembly, or Marshalling Panel cabling is routed in the upper
channel to the left side of the cabinet, and the process control wiring is routed in the lower channel to the
right side of the cabinet.
