3.12.1 Shortening the connecting cable
Note!
The maximum connection length between the probe and separate housing is 6 m and is indicated
by dimension L4. The connection length must be quoted when ordering a Liquicap M with a
separate housing.
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 pressure 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 disc. If
necessary, hold it against the adapter disc (6) using a 34mm open-end wrench.
• Disconnect the adapter disc (6) from the sleeve (17).
• Remove the snap ring using a snap ring pliers.
