4. On the right-side adjacent module, move its bus lever to the

right (unlock) to disconnect it from the module to be removed.

5. Gently slide the disconnected module forward.

If you feel excessive resistance, check that the module has been
disconnected from the bus, and that both mounting screws have
been removed or DIN latches opened.

6. Before installing the replacement module, be sure that the bus

lever on the module to be installed and on the right-side
adjacent module are in the unlocked (fully right) position.

7. Slide the replacement module into the open slot.

8. Connect the modules together by locking (fully left) the bus

levers on the replacement module and the right-side adjacent
module.

9. Replace the mounting screws or snap the module onto the DIN

rail.

Grounding the Module

This product is intended to be mounted to a well-grounded mounting
surface, such as a metal panel. Additional grounding connections from
the module’s mounting tabs or DIN rail (if used) are not required
unless the mounting surface cannot be grounded. Refer to Industrial
Automation Wiring and Grounding Guidelines, publication

for additional information.

TIP

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.
