11.1.1 Wireless THUM with Intrinsically Safe Barrier on TEC2000
An Intrinsically Safe Barrier is available for use with the wireless THUM in oil and gas
applications. The IS Barrier is wired between the THUM and the STC. The IS Barrier is installed
in its own explosion proof case with sealed conduits above and below that separates the
intrinsically safe THUM from the explosion proof TEC 2000. It is important that the seal in the
conduits above and below the IS Barrier is not disturbed when servicing the unit. A wiring chart
for this application is shown below that shows the connections between the THUM and IS
Barrier and between the IS Barrier and the STC.

Verify that all connections are secured and make sure the actuator is configured for
"Network Mode" (Setpoint changes via THUM will not be accepted if not in proper
mode), and then close the actuator.
