Proline Prosonic Flow P 500 HART Electrical connection
Endress+Hauser 55
7.4 Potential equalization
7.4.1 Requirements
For potential equalization:
• Pay attention to in-house grounding concepts
• Take account of operating conditions like the pipe material and grounding
• Medium, Connect the sensor and transmitter to the same electric potential
4)
• Use a ground cable with a minimum cross-section of 6 mm
2
(10 AWG) and a cable lug
for potential equalization connections
