Page 8: Installing The Modules
8 CompactLogix ControlNet Interface Module Installing the Modules This product is grounded through the DIN rail to chassis ground. Use ATTENTION 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.
Page 9 CompactLogix ControlNet Interface Module 9 4. Use M4 or #8 screws to mount the modules to your panel with 1.16 Nm (10 lb-in) of torque. 5. Ground the module on a ground bus with a dedicated Earth-ground stake. 6. Connect the ground bus to a functional Earth-ground on the DIN rail or panel.

Page 16: Connect To A Controlnet Network
16 CompactLogix ControlNet Interface Module Connect to a ControlNet Network The 1768-CNB and 1768-CNBR modules have a network access port (NAP) available. The most common and easiest way to connect to the network is by using the a ControlNet tap. Perform the following steps to connect the module to the network by using a tap.
Page 17 CompactLogix ControlNet Interface Module 17 On 1768-CNBR installations, make sure the correct network is IMPORTANT connected to the correct tap connection. Reversing the tap connections will result in incorrect status display. When you are using redundant media, connect the channel of each partner to the same network segment.
