[. . . ] Adjustment: Scale values represent the lowest switching point, the highest switching point being the switching difference higher. [. . . ] earthing connection / potential equalisation External on the outside of the switching unit. The maximal cross section of the cable is 4 mm2 Switching power AC: 3 A 250 V resistance load, 2 A 250 V inductive load (cos = 0. DC: 0, 1 A 250 V~ resistance load, 0, 01 A 250 V~ inductive load, 2 A 30 V resistance load. Setting of switching point The switching point can be set within the range given in the datasheet by using a screwdriver on the setting spindle. Additionally you should remove the terminal board casing (with 4 hexagon screw M4). The affixing screw on the front end (above the scale) has to be removed and should be reattached after setting the switching point. By turning the setting spindle clockwise gives a lower switching point, by turning anticlockwise gives a higher switching point. The scale should be used as a guide for more exact settings you should use a Manometer. [. . . ] Important notice When installing the Ex switch units and setting them up for operation you should comply with the recognised rules and guidelines for installations in Ex-areas. [. . . ]
