Installation and Wiring Chapter 3
Replace the Module within
a System
The module can be replaced while the system is mounted to a panel or DIN rail.
1. Remove power, referring to the Warning on
page 47.
2. Remove terminal block or disconnect input and/or output wiring from the
module.
3. Remove the upper and lower mounting screws from the module (or open
the DIN latches using a screwdriver).
4. On the module to be replaced and the right-side adjacent module (or end
cap if the module is the last module in the bank), move the bus levers to the
right (unlock) to disconnect the module from the adjacent modules.
5. Gently slide the disconnected module forward.
If you feel excessive resistance, make sure that you disconnected the
module from the bus and that you removed both mounting screws (or
opened the DIN latches).
6. Before installing the replacement module, be sure that the bus lever on the
right-side adjacent module is 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 or end cap.
9. Replace the mounting screws (or snap the module onto the DIN rail).
10. Replace the terminal block or connect the input and/or output wiring to
the module.
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.
