A torque spanner with a tolerance ≤10% should be used for tightening. The specified tightening torques can
be understood as extremely rough and non-binding reference values. See VDI 2230 for the calculation of the
tightening torque. Coefficient of friction µ
6.2.2
Required tools
Only commercially available tools and torque spanners are required to install the pressure switch.
6.3 Installing the pressure switch
DANGER of injury and material damage
The relevant plant part should always be relieved of pressure and de-energized
prior to installing/dismantling the pressure switch.
Use of the pressure switch is only permitted in plants in which the max. operating
pressure Pmax is not exceeded (see technical data or rating plate).
WARNING of risk of injury and material damage
Exceeding of the max. operating pressure Pmax through pressure peaks and
pressure surges and the exceeding of temperature limit values lead to
consequences ranging from behavioural changes to damage.
NOTE
The pressure switch should be installed in a low vibration environment and
protected against pressure surges to increase the service life.
All dimensions relevant to installation and other information can be found in the
technical data for the respective pressure switch.
