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, Allen-Bradley publication 1770-4.1, for additional information. 
Note:
Use the pull loop on the connector to disconnect modules. Do not pull 
on the ribbon cable.
