Installation for level
Note
Seals are required for the installation. The seals must be compatible with the medium to be measured.
Seals are not included in the delivery.
Procedure
To install the transmitter for level, proceed as follows:
1.
Attach the seal to the container's mating flange.
Ensure that the seal is centrically positioned and that it does not restrict the movement of the flange's seal diaphragm in
any way as otherwise the tightness of the process connection is not guaranteed.
2.
Screw on the transmitter's flange.
3.
Observe the installation position.
Connecting

WARNING
Unsuitable cables and/or cable glands
Danger of explosion in hazardous areas if you connect cables and/or cable glands which do not match one another or do
not comply with the technical requirements.
● Only use cables and cable glands complying with the requirements specified in the section Technical data (Page 25).
● Tighten the cable glands in accordance with the specified torques.
● When replacing cable glands use only cable glands of the same type.
● After installation check that the cables are seated firmly.
