Assemble the Compact I/O
System
The module can be attached to the controller or an adjacent I/O
module before or after mounting.
For mounting instructions, see Panel Mounting By Using the
Dimensional Template on page 18, or Mount to a DIN Rail on page
19. To work with a system that is already mounted, see Replace a
Single Module Within a System on page 19.
1. Disconnect power.
2. Check that the bus lever of the module to be installed is in the
unlocked (fully right) position.
3. Use the upper and lower tongue-and-groove slots (1) to secure
the modules together (or to a controller).
4. Move the module back along the tongue-and-groove slots until
the bus connectors (2) line up with each other.
5. Use your fingers or a small screwdriver to push the bus lever
back slightly to clear the positioning tab (3).
