Caution!
• The transmitter (compact and remote version) is to be securely connected to the potential equalization
system using the screw terminal on the outside of the transmitter housing. Alternatively, the transmitter of
the compact version as of serial number 4Axxxxxx000 can be connected to the potential equalization
system via the pipeline if a ground connection via the pipeline according to regulations can be assured.
• With the remote version, the sensor's wiring compartment housing is to be grounded using the external
screw terminal . Alternatively, the sensor can be connected to the potential equalization system via the
pipeline when a ground connection according to regulations can be assured.
