3 Mounting and sensor wiring
3.1 Mounting and sensor wiring for integral-
mount transmitters
There are no separate mounting requirements for integral transmitters, and no need to
connect wiring between the transmitter and the sensor.
3.2 Ground the meter components
Prerequisites
NOTICE
Improper grounding could cause inaccurate measurements or meter failure.
WARNING
Failure to comply with requirements for intrinsic safety in a hazardous area could result
in an explosion causing death or serious injury.
Note
For hazardous area installations in Europe, refer to standard EN 60079-14 or national
standards.
If national standards are not in effect, adhere to the following guidelines for grounding:
• Use copper wire, 14 AWG (2.08 mm
2
) or larger wire size.
• Keep all ground leads as short as possible, less than 1 Ω impedance.
• Connect ground leads directly to earth, or follow plant standards.
Procedure
1. Ground the Coriolis sensor according to the instructions in the sensor installation
manual for your Coriolis sensor.
2. Ground the transmitter according to applicable local standards, using the
transmitter’s internal or external ground screw.
• The internal ground screw is located inside the power wiring compartment.
