Caution:
• The transmitter ➀ (compact and remote version) is to be securely connected to the
potential equalization system using the screw terminal ➁ on the outside of the trans-
mitter housing.
• With the remote version, the sensor's wiring compartment housing ➂ is to be
grounded using the external screw terminal ➃. Alternatively, the sensor can be con-
nected to the potential equalization system via the pipeline when a ground connection
according to regulations can be assured.
The table below contains the values that are identical for all versions, irrespective of the
type code.
