3.5 Grounding the transmitter
The Rosemount 705 Transmitter operates best with the housing grounded. Floating systems,
however, can cause extra noise that may affect the accuracy of the Rosemount 705 Totalizer. If
the signal appears noisy or erratic, grounding at a single point may solve the problem.
Grounding of the electronics enclosure should be done in accordance with local and national
installation codes. Grounding is accomplished through the process connection using the
internal or external case grounding terminal.
Determining grounding requirements
Each process installation has different grounding requirements. Use the options recommended
by the facility for the specific turbine meter or pulse output device.
1. Connect turbine meter wiring shield to the grounded transmitter housing.
2. Ensure the transmitter housing is electrically isolated from the turbine meter or pulse
output device wiring.
