System Assembly
The adapter can be attached to adjacent 1769 modules before or after mounting.
For mounting instructions, see Mount the Adapter with Screws on page 70 , or
Mount on a DIN Rail on page 71 .
Follow these steps to assemble the Compact I/O™ system.
1. Disconnect power.
2. Check that the bus lever of the module to the right of the adapter is in the
unlocked (fully right) position.
3. Use the upper and lower tongue-and-groove slots (a) to secure the modules
together.
4. Move the module back along the tongue-and-groove slots until the bus
connectors line up with each other.
5. Use your fingers or a small screwdriver to push the bus lever of the module
to the right of the adapter back slightly toclear the positioning tab (b).
6. To allow communication between the adapter and I/O modules, move the
bus lever of the module to the right of the adapter fully to the left (c) until
it clicks. Make sure it is locked firmly into place.
IMPORTANT The 1769-AENTR adapter must be used with one of the following Rockwell
Automation power supply models: 1769-PA2, 1769-PB2, 1769-PA4, or
1769-PB4.
WARNING: If you insert or remove the module while backplane power is on, an
electrical arc can occur. This could cause an explosion in hazardous location
installations.
Be sure that power is removed before proceeding.
ATTENTION: When you attach the adapter, it is very important that the bus
connectors are securely locked together to create a proper electrical connection.
