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.
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.
IMPORTANT
The analog base module can accommodate a
maximum of two discrete expansion modules.
