Installing the Module
5. Gently slide the disconnected 1769-SM1 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 1769-SM1 module, be sure that the
bus lever on the right-side adjacent module is in the unlocked (fully
right) position.
7. Slide the replacement 1769-SM1 module into the open slot.
8. Connect the 1769-SM1 module and adjacent modules together by
locking (fully left) the bus levers on the 1769-SM1 module and the
right-side adjacent module.
9. Replace the mounting screws (or snap the module onto the DIN rail).
10. Plug the appropriate 1202-C* communications cable into its
respective port on the 1769-SM1 module.
11. Restore 1769-SM1 module configuration using an appropriate
configuration tools.
Grounding the Module
The 1769-SM1 module 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. For
additional information, refer to Industrial Automation Wiring and
Grounding Guidelines (Publication No. 1770-4.1).
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.
