Potential equalization
• 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.
• When using the remote version, the connection housing of the sensor must be grounded via the external
screw terminal. Alternatively, the sensor can be integrated into the potential equalization via the pipeline
as long as the pipeline provides a ground connection conforming to regulations.
