    Emerson.com/Rosemount. Equipment Damage During normal operation, or in fault condition, the THUM Adapter will cause a 2.5 V drop in the connected loop. It is important to ensure that the power supply can provide at least 2.5 V more than the minimum operating voltage of the wired device to make sure it works properly with the THUM Adapter installed.

    Figure 1-1: THUM Adapter Position Conduit entry When installing the THUM Adapter into the conduit entry of a wired device, use an approved thread sealant. Thread sealant provides a water tight seal. The thread sealant also provides lubrication to ensure easy removal of the THUM Adapter.
  • Page 6 25 mA. Under fault conditions, the maximum voltage drop is 2.5 V. The THUM Adapter will not affect the 4–20 mA signal under normal or fault conditions as long as the loop has at least a 2.5 V margin at the maximum loop current (25 mA for a typical 4–20 mA/HART device).

  • Page 7: Bench Top Configuration

    Bench top configuration When performing bench top configuration it is suggested that you connect the THUM Adapter to a wired device. If this is not possible, the following wiring diagrams can be used. For bench top configuration, ensure the power supply used is limited to 0.5 A maximum.

  • Page 8: Physical Installation

    Quick Start Guide September 2020 Physical installation The THUM Adapter can be installed in one of two configurations: 1. Direct mount: The THUM Adapter is connected directly to the conduit entry of the wired device. 2. Remote mount: The THUM Adapter is mounted separate from the wired device housing and then connected to the wired device using conduit or other suitable means.

  • Page 9: Direct Mount

    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. Procedure 1. Attach the THUM Adapter to the wired device as shown in Figure 4-1. Figure 4-1: Direct Mount 2.

  • Page 10: Remote Mount

    Wire running from the THUM Adapter to the wired device should be shielded or in conduit when installed in electrically noisy environments. 4. Connect the THUM Adapter to the HART wired device using the Wiring diagrams. 5. Close the housing cover on the HART wired device, so that metal touches metal, but do not overtighten to prevent damaging the unit.
