When using shielded cable or shielded thermocouple extension wire,
ground the foil shield and drain wire only at one end of the cable.
We recommend that you wrap the foil shield and drain wire together
and connect them to the “S” connection on the RTP for the particular
channel. All shield connections are internally connected together in
the RTP so that only one wire is required to ground the entire remote
termination panel. Connect a wire from the “SH” connection on the
RTP to a ground stud on the metal cabinet in which the remote
termination panel is mounted.
If you do not want to ground a particular shield at the RTP, you can
remove the jumper for that particular channel. This will allow the
shield to float at the RTP end. To remove a jumper, you must cut it
out. Once the jumper is removed it cannot be replaced. Clip as
close to the circuit board as possible at both ends to completely
remove it. The jumpers (Figure 2.7) are labeled J1 through J8,
corresponding to channels 1 through 8 respectively.
