Installing the Siemens MPI-2 Mounting Plate for your TRI-S, TRI-D, or TRI-R devices on a System 3 Rail Assembly is straightforward. Here's a step-by-step guide:

1. Mounting Plate Installation:

   • Use the four 8 x 1/4 Phillips head screws included to attach the MPI-2 plate to the System 3 Rail Assembly. Secure the screws at the upper and lower corners of the plate, referencing the positions labeled 'A' in the provided diagrams.

2. Device Installation:

   • Mount one or two TRI-S, TRI-D, or TRI-R modules onto the MPI-2 plate, as illustrated in the figure.
   • Utilize four of the 8 x 1/4 Phillips head screws for each TRI module to firmly secure them to the mounting plate.

3. Cover Plate Installation:

   • Attach the BP-30 cover plate to the System 3 door to conceal the MPI-2 plate, providing a polished and professional finish.

4. Additional Guidance:

   • For detailed instructions on routing power-limited and non-power-limited wiring to ensure the proper operation of the devices, consult the System 3 Control Panel Installation Instructions (Part Number 315-093680).
