1-6 Installing Your DeviceNet Adapter Module
DIN Rail Mounting
The adapter can be mounted using the following DIN rails:
• 35 x 7.5mm (EN50022 - 35 x 7.5)
• 35 x 15mm (EN 50022 - 35 x 15)
Before mounting the module on a DIN rail, close the DIN rail latches.
Press the DIN rail mounting area of the module against the DIN rail.
The latches will momentarily open and lock into place.
Replacing the 1769-ADN
within a System The adapter can be replaced while the system is mounted to a panel
(or DIN rail).
1. Remove power. See important note on page 1-2.
2. Remove the DeviceNet cable from the module by loosening the
upper and lower retaining screws of the DeviceNet connector
and removing the connector from the module.
3. Remove the upper and lower mounting screws from the adapter
(or open the DIN latches using a flat-blade or phillips-style
screwdriver).
4. On the right-side adjacent module, move its bus lever to the
right (unlock) to disconnect it from the adapter being removed.
5. Gently slide the disconnected adapter forward.
If you feel excessive resistance, make sure that you
disconnected the adapter from the bus and that you removed
both mounting screws (or opened the DIN latches).
Note: It may be necessary to rock the module slightly from front
to back to remove it, or, in a panel-mounted system, to loosen
the screws of adjacent modules.
6. Before installing the replacement adapter, be sure that the bus
lever on the right-side adjacent module is in the unlocked (fully
right) position.
7. Slide the replacement adapter into the open slot.
8. Connect the adapter and modules together by locking (fully left)
the bus lever on the right-side adjacent module.
9. Replace the mounting screws (or snap the adapter onto the DIN
rail).
