DeviceNet Digital Base Terminal Block CompactBlock LDX I/O Mount on a Panel For panel mounting, use these steps. 1. Place the block against the panel where you want it mounted. 2. Gently pull and position the expansion cover to the left. 3. Place a center punch, nail, or similar device through the mounting holes in the block and make two marks on the panel at the lower-left and upper-right corners of the module. 4.

Mount the Optional Expansion Block To mount the optional expansion block, use these steps. 1. Mount the expansion block by connecting it to a previously-installed CompactBlock LDX I/O base or expansion block. 2. Beginning with the base block, mount your expansion block either horizontally or vertically.
DeviceNet Digital Base Terminal Block CompactBlock LDX I/O • To mount vertically (up or down), add an expansion block either up or down in a back-to-back configuration. In this configuration, you must use the optional 15 cm (5.9 in.) ribbon cable, catalog number 1790-15CMCBL, and alternately position the block in a right-side up, upside-down fashion. Right Side Up The longer expansion cable, catalog number 1790-15CMCBL, provides for up to 7 cm (2.76 in.) of space between blocks.
