ATTENTION The field wiring to Galvanically Isolated FTAs must be routed such that a strict 2-inch minimum separation is maintained between any other wiring, cable, or electrical part, or be separated by a divider that is grounded metal or nonconductive material. FTA Mounting Channels 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 FTA to IOP cabling, and the process control wiring. The standard (non-Galvanically Isolated) FTA to IOP or Power Distribution Assembly cabling is routed in the right channel, and the process control wiring is routed in the left channel. The reverse is true for Galvanically Isolated FTAs because the FTA Mounting Channel is installed in an inverted position. Power Distribution and Marshalling Panels The model MU/MC-GPRD02 Power Distribution Panel can be mounted on any FTA Mounting Channel that is installed in the normal or inverted position; however, proper wiring separation must be observed. The model MU/MC-GMAR52 Marshalling Panel must not be mounted on an FTA Mounting Channel that has a Galvanically Isolated FTA mounted on it. 4.2 FTA Selection Overview The FTA has circuits that convert the process control signals to voltage and current levels that can be accommodated by the High-Performance Process Manager electronics. There are a number of FTA types with each type designed for a specific type of signal. Rules Rules for selecting the appropriate FTAs, installing, configuring, and the connections to the associated IOP and the process control signals, are discussed in detail in the Process Manager I/O Installation manual.
