Mount the Expansion Module
Mount the expansion module and connect it to a
previously-installed CompactBlock LDX I/O base or expansion
Beginning with the base module, you can mount your
CompactBlock LDX I/O modules either horizontally or
vertically:
• horizontally (left to right) - add expansion modules in a
end-to-end configuration
• vertically (up or down) - add expansion modules either up
or down in a back-to-back configuration. In this
configuration, you must use the optional 15cm ribbon cable
(1790-15CMCBL) and alternately position the modules in a
right-side up, upside-down fashion.
You can mount your modules on a panel or DIN rail as
described in the following section.
