Assembly information
Please observe the following device assembly notes. This information serves your own safety and guarantees smooth installation and low-
maintenance and reliable operation of your transmitter.
The plant must be returned to the ambient pressure before assembly. Failure to do so brings the danger of flying
parts or the sudden release of gases or other media.
Before assembly, ensure that the locations affected does not become too hot for working without danger. Allow
the surfaces and attachments to cool before assembly.
Continue to be aware of the danger of cold burns on strongly-cooled system components. Ensure that you can
work without danger.
Ensure that you do not come into contact with aggressive residual media remaining in the plant during assembly.
Make sure that the potential equalisation between the transmitter and plant is facilitated. In this respect, please
also read the section regarding the electrical connections of the device.
Do not remove the protective cover from the measuring cell during the assembly preparations. Only remove the
cover shortly before installing the transmitter. Make sure that you don't touch the membrane during the
installation.
The device manufacturer recommends that device openings such as ventilation openings should point downwards
during the installation if possible. This way, in the event that process media make the device wet, its blockage by
highly viscose or drying substances is avoided.
The device should be installed in a low-vibration location and with some distance to larger plants and strong
electrical fields if possible.
Make sure that the process connection with the plant has a tight fit and no medium leaks from the connection
point. For this purpose, use a seal which is suited for your specific process, and pay special attention to its
suitability for the process temperature and compatibility with the medium.
Tighten the transmitter with the torque that is suitable for your process connection. If in doubt, please contact the
manufacturer. Under certain circumstances, metal screw connections damaged by improper installation may not
be able to be loosened without causing problems.
If the provided reference cable is used, please observe a minimum bending radius of the cable of 120 mm. Protect
the cable against the ingress of moisture by making sure that it ends inside a dry room.
