Chapter 6 Install ControlLogix Isolated Analog I/O Modules
Connect the Grounded End of the Cable
Before wiring the RTB, you must connect the ground wiring.
1. Remove a length of cable jacket from the Belden cable.
2. Pull the foil shield and bare drain wire from the insulated wire.
3. Twist the foil shield and drain wire together to form a single strand.
4. Attach a ground lug and apply heat shrink tubing to the exit area.
IMPORTANT We recommend that you ground the following ControlLogix isolated analog
module shield and drain wires at the field-side:
• 1756-OF8I
• 1756-IRT8I
• 1756-IF8I on points that use the non-sourcing current/voltage
functionality
If you cannot ground the module shield and drain wires at field-side, ground
them at an earth ground on the chassis.
We recommend that you always ground the 1756-IF8I module at an earth
ground on the chassis when you use the module’s current sourcing
functionality.
