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