3 INSTALLATION
Ensure the equipotentiality of the installation (power supply - transmitter - fluid):
- The various earth spots in the installation have to be connected together to
eliminate the potential differences that may occur between different earthes.
- Observe faultless grounding of the shield at both ends of the cable.
- Earth the negative terminal of the power supply to suppress the common mode
currents. If direct earthing is not possible insert a 100 nF / 50 V-condensator
between the negative terminal and the earth.
Special attention has to be paid if the transmitter is installed on plastic pipes because there
is no direct earthing possible.
Proper earthing is performed by earthing together the metallic devices such as pumps or
valves, that are as close as possible to the transmitter.
Realizing (principle) the equipotentiality of a compact version:

(*) If direct earthing is impossible, connect a 100 nF / 50 V-condensator between the negative terminal and the
earth.
