System Assembly
The module can be attached to the controller or an adjacent I/O module before or after
mounting. For mounting instructions, see the Panel Mounting or DIN Rail Mounting
sections. To work with a system that is already mounted, see Replacing a Single Module within
a System section.
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. Push the bus lever back slightly to clear the positioning tab (3). Use your fingers or a
small screw driver.
ATTENTION
Remove power before removing or inserting this module. When you
remove or insert a module with power applied, an electrical arc may occur.
An electrical arc can cause personal injury or property damage by:
• sending an erroneous signal to your system’s field devices, causing
unintended machine motion
• causing an explosion in a hazardous environment
Electrical arcing causes excessive wear to contacts on both the module
and its mating connector. Worn contacts may create electrical resistance.
