The power supply for the pressure transmitter must be made via an energy-limited electrical 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 power supply must

be suitable for operation above 2,000 m should the pressure transmitter be used at this altitude.
