Conduit electrical connector wiring (option GE or GM)

For 3051S Transmitters with conduit electrical connectors GE or GM, refer to the

cordset manufacturer’s installation instructions for wiring details. For FM

Intrinsically Safe, non-incendive or FM FISCO Intrinsically Safe hazardous

locations, install in accordance with Rosemount drawing 03151-1009. See

Appendix B of the 3051S Reference Manual.

Power supply

The DC power supply should provide power with less than two percent ripple. The

total resistance load is the sum of the resistance of the signal leads and the load

resistance of the controller, indicator, and related pieces. Note the resistance of

intrinsic safety barriers, if used, must be included.
