Procedure
1.
Screw the cable gland (E) into the transmitter housing.
2.
Guide the sensor connecting cables through the cable gland cover (F).
3.
Threat the sensor connecting cables into the transmitter housing.
Align the outer end of the rubber grommet with the end of the cable gland/grounding
mechanism. This ensures that the cable entry will be a) tight and b) the cable is correctly
grounded to the transmitter housing at the internal contact point (D) once tightended.
An external inspection is not possible, so it is important to follow this instruction.
4.
Tighten the cable gland by turning the cable gland cover clockwise.
!
Note!
The red marked cable is sensor "up"; the blue marked cable is sensor "down".
!
Note!
The cable gland can be released from the cable by unscrewing and removing tha cable gland cover.
Then retract the grounding mechanism (G) with pair of pliers. The retraction of the mechanism does
not require strong force (strong force might destroy the screen). It might be required to lift the
internal hooks of the grounding mechanism out of a locked position by pressing the grounding
mechanism further forward by turning the cable gland clockwise. Remove the cable gland cover
again. Then retry to retract with the pair of pliers.
