• The operator must carefully select the correct tube diameter with respect to the expected
flow rates.
• The device must not be exposed to excessive vibration during operation.
• It is the responsibility of the operator to ensure that wetted material is compatible with
process fluid.
• Correctly sized cables for the cable glands must be used and the cable glands and the lid
must be tightened sufficiently. Furthermore the device (lid, cable glands) must not be opened
during safe operation.
• If the safe current output is used in passive configuration an overvoltage at the terminal can
lead to a leakage current in the device's input protection circuit and loss of the safety function
of the device. It is necessary to use a power supply with voltage limitation or voltage
monitoring.
WARNING!
In safety-related applications you must follow the installation instructions given in the
handbooks of the sensor and the converter ([N1], [N2]). The device must be installed by properly
trained and authorised personnel.
