CompactLogix Selection Guide
Step 6 - Select:
y Panel mount or DIN rail mount
y Appropriate number of panels or DIN
rails based on the number of modules
and the physical location
y Expansion cables
Mount the CompactLogix System
You can panel mount or DIN-rail mount a CompactLogix system. The CompactLogix system
must be mounted so that the modules are horizontal to each other.
If you decide to use a DIN rail, use steel, 35 x 7.55mm DIN rails (A-B part number 199-
DR1; 46277-3; EN 50022). The DIN rails for all CompactLogix system components must be
mounted on a common, conductive surface to be sure of proper electromagnetic
interference (EMI) performance.
