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 dif-
ferent 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.
