How do I install the Siemens MPI-2 Mounting Plate for TRI-S devices on a System 3 Rail Assembly?

[MacMariana]

Installing the Siemens MPI-2 Mounting Plate for TRI-S, TRI-D, or TRI-R addressable devices on a System 3 Rail Assembly is straightforward. First, secure the MPI-2 plate to the rail assembly using the four provided 8 x 1/4 Phillips head screws. Attach the screws at the upper and lower corners, referencing position A on the plate diagram. Next, mount one or two TRI-S, TRI-D, or TRI-R modules onto the MPI-2 plate. Use four more of the 8 x 1/4 Phillips head screws for each TRI module to firmly attach them to the mounting plate. Finally, install the BP-30 cover plate in the System 3 door to cover the MPI-2 plate, which provides a clean finish. For detailed guidance on power-limited and non-power-limited wire routing to ensure your devices function correctly, consult the System 3 Control Panel Installation Instructions (P/N 315-093680) from Siemens Industry, Inc.
