When using shielded cable or shielded thermocouple extension wire,
ground the shield at only one end of the cable. Because we don’t know
whether you have the ability to provide a good ground at the other end, we
recommend that you connect the shield drain wire 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. Ground the RTP by connecting a wire
from the “SH” connection on the RTP to a ground bus in 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. If you cut
out a jumper, clip it as close to the circuit board as possible at both ends.
Once the jumper is removed it cannot be replaced. The jumpers
(Figure 2.6) are labeled J1 thru J8, corresponding to channels 1 thru 8
respectively.
