Safety instruction

WARNING
Risk of burns due to hot measuring media.
The insertion sensor surface temperature may exceed
70 °C (158 °F), depending on the measuring medium
temperature! Before starting work on the insertion
sensor, make sure that it has cooled sufficiently.
If there is a chance that safe operation is no longer possible,
take the insertion sensor out of operation and secure it against
unintended startup.

Checks prior to commissioning

The following points must be checked before commissioning
the insertion sensor:
• The wiring must have been completed as described in the
Installation section on page 15.
• The insertion sensor must be grounded correctly.
• The ambient conditions must meet the requirements set
out in the technical data.
• The power supply must meet the requirements printed on
the identification plate.
• Checking the correct insertion sensor to transmitter
assignment (remote flowmeter only – see page 8 for
insertion sensor label information.
IMPORTANT (NOTE)
The Flow Settings > Mains Noise Rejection Frequency
(Hz) setting must match the mains frequency
supplied at the point of installation – refer to
Operating Instruction OI/FET400-EN.
