Module Components
The illustration shows the components that comprise the 1786-RPFS module.
Mount the Module
Mount the module on a 35 x 7.5 mm (1.38 x 0.30 in.) DIN rail, Allen-Bradley 
part number 199-DR1, 46277, EN 50022.
ATTENTION: This product is grounded through the DIN rail to 
chassis ground. Use zinc plated yellow-chromate 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.
TIP
Horizontal mounting is preferred. Vertical mounting is allowed. 
We recommend that the 1786-RPA/B repeater adapter module be 
mounted at the top if vertical mounting is chosen.
