Grounding the Controller
This product is intended to be mounted to a well grounded mounting surface
such as a metal panel. Refer to the Industrial Automation Wiring and Grounding
Guidelines, publication 1770-4.1 , for additional information.
Wiring Diagrams
The following illustrations show the wiring diagrams for the Micro800
controllers. Controllers with DC inputs can be wired as either sinking or sourcing
inputs. Sinking and sourcing does not apply to AC inputs.
High-speed inputs and outputs are indicated by .
