TRICONEX PLM 3900N Safety Redundant I/O Module
Attach the other end of the interface cable to the ELCO connector directly above the
corresponding I/O module on the Tricon backplane in the same manner as you
connected the cable to the termination panel, as described in step4.
6 Attach the wires from your field devices to the screw terminals on the termination panel.
See the Torque Specifications for Field Wiring Terminals section.
7 Perform a static check of the wiring.
8 If Tricon power was removed in step 1. restore power to the Tricon system.
9 Apply field power to the termination panel.
10 Verify that all I/O points are connected to the appropriate field devices and are
operating correctly.
Note To inspect input points and force output points, see the Planning and Installation
Guide for Tricon v9–v10 Systems.
11 Load and test the control program using TriStation.
If the program operates as intended, you are ready to enable the process equipment according
to the safety requirements for your environment.
If you need additional information on how to install external field termination panels, contact
the IPS Global Client Support (GCS) center.

Removing or Replacing a Termination Panel
This procedure explains how to remove or replace a termination panel.
Procedure
1 Remove field power from the termination panel.
2 Detach all I/O points connected to the appropriate field wiring.
3 Detach the wires from your field devices to the screw terminals on the termination
panel.
4 Detach the interface cable from the ELCO connector on the termination panel.
• As you pull the connector on the cable, use your other hand to turn the thumbscrew
counter-clockwise. You may need to rock the connector slightly while pulling.
• Ensure that the mating surfaces of the ELCO connectors on the cable and the
termination panel do not have any bent pins or other damage.
5 Detach the other end of the interface cable from the ELCO connector on the Tricon
backplane in the same manner as you disconnected the cable from the termination panel,
as described in step 4
