8.3.2 Making the installation equipotential
To ensure the equipotentiality of the installation (power supply - device - medium):
→ Connect together the various earth spots in the installation to eliminate the potential differences that may
occur between different earthes.
→ Observe faultless grounding of the shield of the power supply cable. Refer to Fig. 13 and Fig. 14.
→ If the device is installed on plastic pipes, earth together the metallic equipment such as pumps or valves, that
is as close as possible to the device. Refer to Fig. 14.
