! Ensure that the system is under any pressure before installing or removing the sensor.
Connect the sensor device to the selected process port
Fully tighten, recommended tightening torque range: 25 to 35Nm
In critical applications (such as violent vibrations or shocks), the pressure pipe joint
can be mechanically decoupled via a miniature hose.

Safety instructions are intended to protect users from dangerous situations and/or
prevent material damage. In the operating instructions, the severity of the potential risk can
be indicated by the following signal words:
Install
Sensors (switches) should only be installed in systems that do not exceed the maximum
pressure Pmax (see type label).
Install sensors (switches) only when power is off (electric, hydraulic/pneumatic).
!
danger
Vibration and violent vibration must be avoided during transportation. Even if the sensor
(switch) housing is not damaged,
Internal components can also break down and cause failure.
