Shielding and potential equalization

Please take note when installing the device:
If screened (shielded) cables are used then the shielding connected to the output (output signal 4 to
20 mA) must be at the same potential as the shielding at the sensor connection!
When operating in plants with high electromagnetic fields, it is recommended that all cables be
shielded using a low ohm ground connection. Due to the possible danger of lightning strikes,
shielding is also recommended for cables that are run outside buildings!
