Chapter 2 Installation and Wiring
Panel Mounting
1. Place the block against the panel where you want to mount it.
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 (lower left and upper right
corners of the module).
4. Remove the block and drill two holes in the panel to accommodate each
of the mounting screws.
5. Replace the block on the panel and place a screw through each of the two
mounting holes. Tighten the screws until the block is firmly in place.
DIN Rail Mounting
1. Hook the top of slot of the block over the DIN Rail.
2. Pull down on the locking lever while pressing the block against the rail.
3. Push up on the locking lever to secure the block to the rail when block is
flush against the rail.
Mount the Optional Expansion Blocks
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
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 15 cm (5.90 in.) ribbon cable (1790-15CMCBL) and alternately
position the blocks in a right-side up, upside-down fashion.
You can mount your blocks on a panel or DIN rail as described in the previous
section.
