5.4.1 Requirements for voltage supply
→ For power supply see product label
The power supply for the pressure sensor must be made via an energy-limited electric circuit in accordance with
section 9.4 of UL/EN/IEC 61010-1, or an LPS per UL/EN/IEC 60950-1 / CSA C22.2 no. 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.
5.4.2 Requirements for electrical connection
Ingress protection of the mating connector corresponds to the ingress protection of the pressure sensor.
■
Cable diameter matches the cable bushing of the mating connector.
■
Cable gland and seals of the mating connector are correctly seated.
■
No humidity can ingress at the cable end.
■
5.4.3 Requirement for shielding and grounding
The pressure sensor must be shielded and grounded in accordance with the grounding concept of the application.
Take measures to prevent electrostatic discharge on the connection terminals, as a discharge could lead to temporary
corruption of the measured value.
