Figure 5. Remote Mount
1. Install the HART device according to standard installation practices and the
manufacturer’s instructions, being sure to use an approved thread sealant on all
connections.
2. The THUM Adapter should be mounted as shown in Figure 5 on page 6.
3. Ground the Remote Mount Kit per local practices.
4. Connect the THUM Adapter to the wired device using standard practices. Wire running
from the THUM Adapter to the wired device should be shielded or in conduit when
installed in electrically noisy environments.
5. Connect the THUM Adapter to the HART wired device using the wiring diagrams below.
See Figure 21, 8, 10, and 12 on the following pages.
6. Close the housing cover on the HART wired device, so that metal touches metal, but do
not over tighten to prevent damaging the unit.
NOTE
Two splice connectors are included with the THUM Adapter. The first is a two
connection splice. The second is a three connection splice for use with a resistor, if
there is not enough resistance in the loop. Both of these splice connectors can
accept 14 to 22 gauge wire. See wired device reference manual for information on the
required loop resistance.
