and cable entry are distinct different for the two sensor connection types.
4.1.1 Procedure
!
Note!
The outer shield of the sensor connecting cable (triaxial cable) is grounded by a ground disk in
the cable feedthrough (A). This grounding is absolutely essential to ensure correct
measurement.
1. Unscrew the cover (c) of the cable gland (A). Remove the rubber seal (d).
2. Guide the sensor connecting cables (a, b) through the cover of the cable gland.
3. Guide the sensor connecting cables individually through the ground disk in the cable gland
holder (g) and into the connection compartment.
4. Plug in the connectors of the sensor connecting cables.
Left sensor upstream (a), right sensor downstream (b).
The connector engages with a click when correctly plugged in.
5. Spread the rubber seal (d) along side slits (e.g. using a screwdriver) and fix the cables in
place appropriately. Push up the rubber seal in the cable gland until the sensor cable
sleeves are pressed against the ground disk.
6. Close the cover of the cable gland (c) so that it is tight.
7. In the connection compartment, fix the two sensor connecting cables in place in the
holder (i) provided.
