    FLEX I/O 48V DC Digital Input and Output Modules  

Publication 1794-IN105C-EN-P - July 2018

ATTENTION: 

This product is grounded through the DIN rail to chassis ground. 

Use zinc plated chromate-passivated steel DIN rail to assure proper grounding. 
The use of other DIN rail materials (for example, aluminum or plastic) that can 
corrode, oxidize, or are poor conductors, can result in improper or intermittent 
grounding. Secure DIN rail to mounting surface approximately every 200 mm 
(7.8 in.) and use end-anchors appropriately.  Be sure to ground the DIN rail 
properly.

ATTENTION: 

Refer to Industrial Automation Wiring and Grounding 

Guidelines, Rockwell Automation publication 

1770-4.1

, for more information.

ATTENTION: 

If this equipment is used in a manner not specified by the 

manufacturer, the protection provided by the equipment may be impaired.

ATTENTION:
