Publication 1790-IN003B-EN-P - January 2015 6 Digital Expansion D-Shell Module CompactBlock LDX I/O Overview This document describes how to install your CompactBlock LDX™ I/O expansion I/O modules. Install Your Module Follow these steps to install the expansion module: 1. Mount the module. 2. Connect an expansion module to a base module. 3. Wire the D-Shell connectors. 4. Troubleshoot with the indicators. These steps are explained in detail in the following sections. Mount the Expansion Module Mount the expansion block by connecting it to a previously-installed CompactBlock LDX I/O base or expansion block. Beginning with the base block, you can mount your expansion blocks either horizontally or vertically: • horizontally (left to right) – add expansion blocks in an end-to-end configuration • vertically (up or down) – add expansion blocks 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 blocks in a right-side up, upside-down fashion. Mount the Base Block You can mount the base block to a panel or DIN rail. We recommend that you ground the panel or DIN rail before mounting the block. IMPORTANT The analog base module can accommodate a maximum of two discrete expansion modules.
