The tests of clamping ranges and torque values were performed with metal mandrel. The clamping range can
vary by using cables with different manufacturing tolerances and material properties. Please use a suitable
combination of seals in the intermediate area, so that the cap nut can be tightened in future maintenance
work on the cable entry.
