Replacing a Single Module within a System
The module can be replaced while the system is mounted to a panel (or
DIN rail). Follow the steps below in order:
1. Remove power. See important note on page 4.
2. On the module to be removed, remove the upper and lower mounting
screws from the module (or open the DIN latches using a flat-blade or
phillips-style screwdriver).
3. Move the bus lever to the right to disconnect (unlock) the bus.
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).
