NOTICE
Direct sunlight
Increased measuring errors.
● Protect the device from direct sunlight.
Make sure that the maximum ambient temperature is not exceeded. Refer to the information
in the section Technical data (Page 191).
5.1.1.1
Devices with marine approval
Note
For vibrations in the direction of the measuring cell diaphragm, the measuring accuracy of the
pressure transmitter with flush-mounted diaphragm can deviate no more than 0.2% from the
respective specification.
● Install the device so that no or almost no vibrations occur in the direction of the diaphragms.
● To avoid measuring values that fluctuate strongly, use the damping function.
For information on vibration resistance, refer to the marine approval certificate.
5.1.2
Proper mounting
WARNING
Incorrect mounting at Zone 0
Risk of explosion in hazardous areas.
● Ensure sufficient tightness at the process connection.
● Observe the standard IEC/EN 60079-14.
CAUTION
Loss of type of protection
Damage to device if the enclosure is open or not properly closed. The type of protection
specified on the nameplate or in Technical data (Page 191) is no longer guaranteed.
● Make sure that the device is securely closed.
