the Local Display Module is installed on the Backplane, use a flat blade screw driver
and install the four flat-head screws into the enclosure standoffs.
11. Reinstall the J7 terminal block, if removed, on the Backplane board. Re-install the
CPU Module, Optional I/O Module (if installed) and the Power Supply.

13. If replacing other electronics, continue with the following procedures before
replacing the end caps and sealing the enclosure.
14. If you are not replacing other electronics, replace the end caps and security latches
(3 mm Allen wrench required). If required, install the security seal wire into and
through one of the two holes in the end cap. Choose holes that minimize
counterclockwise rotation of the end cap when the security wire is taut (maximum
wire diameter .078 inch; 2.0 mm).
