8.4.2 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 earthing of the shield of the power supply cable, at both ends.
→ If the device is installed on plastic pipes, earth together the metallic instruments such as pumps or valves, that
are as close as possible to the device.
