7.3 Grounding

Earth/Machine Ground
The LLE is earth grounded through the process connection to the
tank with the assumption that the tank is grounded. If the tank is not
grounded then a ground will need to be connected to the housing of
the LLE. Without correct grounding the overvoltage protection will be
compromised.
Shield Ground
Immunity performance of the sensor from external sources of surge,
burst, RF, radiated emissions and other noise is dependent on a proper
ground for the shield of the communications cable. The communica-
tions cable shield should be of a braided type and connected to the
internals.
