2-20 Installing Your Controller
To attach and lock modules:
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.
6. 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.
7. Attach an end cap terminator (5) to the last module in the system by using the
tongue-and-groove slots as before.
8. Lock the end cap bus terminator (6).
See Controller Dimensions on page A-7 for mounting dimensions.
NOTE
Remove ESD barrier when attaching I/O modules to a
MicroLogix 1500 base unit.
ATTENTION
!
When attaching I/O modules, it is very important that the
bus connectors are securely locked together to ensure proper
electrical connection.
IMPORTANT
A 1769-ECR right end cap (or a 1769-ECL left end cap if I/O
bank is located below the controller) must be used to terminate
the end of the serial communication bus.
