DeviceNet 32 Point Digital Base Terminal Block CompactBlock LDX I/O Mount on DIN Rail For DIN-rail mounting, use these steps. 1. Hook the top slot of the base block over the DIN rail. 44253 Locking Lever 2. Pull down on the locking lever while pressing the base block against the rail. 3. Push up on the locking lever to secure the base block to the rail when the base block is flush against the rail. Mount the Optional Expansion Block To mount the optional expansion block, use these steps. 1.
DeviceNet 32 Point Digital Base Terminal Block CompactBlock LDX I/O 9 • 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.
