Proline Promag L 800 Electrical connection
Hauser 43
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.
The required ground cable can be ordered from Hauser.
Metal, ungrounded pipe without liner
This connection method is also to be used when:
• Potential equalization is not customary
• Equalizing currents are present

Abb. 27: 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 Hauser.
