Proline Promag W 800
16 Endress+Hauser
Connection example in special situations
Metal, ungrounded pipe without liner
This connection method is also to be used when:
• Potential equalization is not customary
• Equalizing currents are present
A0016317
Potential equalization via ground terminal and pipe flanges
For mounting consider the following:
• Connect both sensor flanges to the particular pipe flange via a ground cable and ground them.
Ground cable = copper wire, at least 6 mm² (0.0093 in
²
).
• Connect the transmitter or sensor connection housing, as applicable, to ground potential by means
of the ground terminal provided for the purpose. For mounting the ground cable:
–If DN 300 (12"): Mount the ground cable directly on the conductive flange coating of the sensor
with the flange screws.
–If DN 350 (14"): Mount the ground cable directly on the metal transport bracket.
For remote version: The ground terminal in the example refers to the sensor and not to the
transmitter.
The required ground cable can be ordered from Endress+Hauser ä 53.
Plastic pipe or pipe with insulating lining
This connection method is also to be used when:
• Potential equalization is not customary
• Equalizing currents are present
A0016318
Potential equalization via ground terminal and ground disk
For mounting consider the following:
The ground disks have to be connected to the ground terminal via a ground cable and to the ground
potential. Ground cable = copper wire, at least 6 mm² (0.0093 in²).
For remote version: The ground terminal in the example refers to the sensor and not to the
transmitter.
