1) Check that the bus lever of the module to be installed is in the unlocked (fully
right) position.
2) Use the upper and lower tongue-and-groove slots (1) to secure the modules
together (or to a controller).
3) Move the module back along the tongue-and-groove slots until the bus
connectors (2) line up with each other.
4) Push the bus lever back slightly to clear the positioning tab (3). Use your fingers
or a small screwdriver.
5) To allow communication between the controller and module, move the bus lever
fully to the left (4) until it clicks. Ensure it is locked firmly in place.
When attaching I/O modules, it is very important that the bus

connectors are securely locked together to ensure proper electrical
connection.
