3.7.1 Shortening the connecting cable
A recalibration must be performed before commissioning see Page 56 ff.
Note!
The maximum connection length between the probe and separate housing is 6 m and is indicated
by dimension L4. When ordering a device with a separate housing, the connection length must be
specified.
If the connecting cable is to be shortened or guided through a wall, it must be disconnected from
the process connection. To do so, proceed as follows:
• Unscrew the pressing screw (1) using a 22mm open-end wrench. If necessary, hold the process
connection. In doing so, ensure that neither the connecting cable nor the probe is turned in the
process.
• Pull the insert seal (2) out of the cable gland (3).
• Using a 22mm open-end wrench, disconnect the cable gland (3) from the adapter disk. If
necessary, hold it against the adapter disk (6) using a 34mm open-end wrench.
• Disconnect the adapter disk (6) from the sleeve (17).
• Remove the snap ring using a snap ring pliers.
• Using pliers, grab the nut (M6) on the Multilam plug and pull out the plug.
• Disconnect the connection between the yellow and red (guard) wires.
• Then, shorten the connecting cable to the desired length. If the separate housing is in a different
room than the probe, you can now route the connecting cable through the wall.
• You can now reassemble the device by following the reverse order of steps.
Note!
• If you shorten the connecting cable, we recommend reusing all strands with ring terminals.
• If the wires are not reused, the crimp connections of the newly attached eyelets must be insulated,
for example using a heat-shrinking sleeve (danger of short circuit).
• All soldered joints must be insulated.

3.8.1 Wall holder unit
Note!
The wall holder unit first has to be screwed to the separate housing before you can use it as a drilling
template. The distance between the holes is reduced by screwing it to the separate housing.
