4 Compact™ Combination Analog I/O Module
Publication 1769-IN057A-EN-P - July 2001
System Assembly
The module can be attached to the controller or an adjacent I/O module before or
after mounting. For mounting instructions, see “Panel Mounting” on page 6, or
“DIN Rail Mounting” on page 7. To work with a system that is already mounted, see
“Replacing a Single Module within a System” on page 7.
The following procedure shows you how to assemble the Compact I/O system.
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 (A) to secure the modules
together (or to a controller).
4. Move the module back along the tongue-and-groove slots until the bus
connectors (B) line up with each other.
5. Push the bus lever back slightly to clear the positioning tab (C). Use your
fingers or a small screwdriver.
6. To allow communication between the controller and module, move the bus
lever fully to the left (D) until it clicks. Ensure it is locked firmly in place.
ATTENTION
!
When attaching I/O modules, it is very important that the bus
connectors are securely locked together to ensure proper
electrical connection.
