10. Turn the display cover clockwise until it is snug.
11. Replace the end-cap clamp by reinserting and tightening the cap screw.
12. Restore power to the transmitter.
3.5 Ground the flowmeter components
In 4-wire remote installations, the transmitter and sensor are grounded separately.
CAUTION!
Improper grounding could cause inaccurate measurements or flow meter failure. Failure to
comply with requirements for intrinsic safety in a hazardous area could result in an explosion.
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 (2.5 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.
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.
