5.9 Ground the meter components
In a remote core processor with remote sensor installation, the transmitter, remote core
processor, and sensor are all grounded separately.
Prerequisites
CAUTION!
Improper grounding could cause inaccurate measurements or meter failure.
If national standards are not in effect, adhere to the following guidelines for grounding:
• Use copper wire, 14 AWG (2.5 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 sensor according to the instructions in the sensor documentation.
2. Ground the transmitter according to applicable local standards, using the
transmitter’s internal or external ground screw.
