The switching function of switch point 1 can be set to normally closed or normally open using
the teach function.
Power supply - 1 V
max. 250 mA to 80 °C [176 °F]

The power supply for the pressure sensor must be made via an energy-limited electric circuit in
accordance with section 9.3 of UL/EN/IEC 61010-1 or an LPS to UL/EN/IEC 60950-1 or class
2 in accordance with UL1310/UL1585 (NEC or CEC). The voltage supply must be suitable for
operation above 2,000 m should the pressure sensor be used at this altitude.
