 15 Potential equalization via ground terminal and pipe flanges
Note the following when installing:
• Connect both sensor flanges to the pipe flange via a ground cable and ground them.
• Connect the connection housing of the transmitter or sensor to ground potential by means of the
ground terminal provided for the purpose.To mount 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.
