Remote Termination Panels

If your controller will be mounted in a separate panel with intermediate terminations between field wiring
and controller wiring, consider using RTPs to replace the intermediate terminations. Pre-wired cable
assemblies for the RTPs eliminate the need for separate wiring terminations between the controller and
the intermediate terminal boards. For details see page 221.

Environment

The ControlEdge HC900 Controller must be mounted in suitable equipment enclosures. That is, all
components such as the Controller rack, I/O Racks, and the 900CS Control Station manufactured by
Honeywell must be mounted in approved furniture designed for industrial applications.
Consideration should be given to the installation so that the potential for the build-up of static electricity
is minimized or eliminated.
