Panel Mount the System
To mount your system to a panel, complete these steps.
1. Using the assembled system as a template, carefully mark the center of all mounting holes
on the panel.
2. Remove the system and drill and tap the mounting holes for the recommended M4 or #8
screws.
3. Place the grounding panel (if used) and CompactLogix system on the panel to check for
proper hole alignment.
4. Insert the recommended screws into the mounting tabs on the packaged controller and
expansion modules (if used) and tighten.
DIN-rail Mount the System
To mount your system on a DIN rail, complete these steps.
The packaged controller can be mounted on these DIN rails:
•
EN 50 022 - 35 x 7.5 mm (1.38 x 0.30 in.)
•
EN 50 022 - 35 x 15 mm (1.38 x 0.59 in.)
ATTENTION: When this product is grounded through the DIN rail to chassis ground, use
zinc-plated yellow-chromate steel DIN rail to assure proper grounding. The use of other DIN rail
materials (for example, aluminum or plastic) that can corrode, oxidize, or are poor conductors, can
result in improper or intermittent grounding. Secure DIN rail to mounting surface approximately
every 200 mm (7.8 in.) and use end-anchors appropriately.
