and-groove slots described earlier to attach a 1769-ECR Compact I/O

in the Compact I/O Expansion Power Supplies installation instructions,

IMPORTANT You must install an end cap onto the right side of the
CompactLogix 5370 L3 controller system either at the end of the
controller. You must also install an end cap at the end of any local
expansion modules that can be installed onto the controller.
