Electrical connection
Connect the instrument to earth via the pressure connection.
Operate the pressure sensor with a shielded cable and earth the shield at least on one
side of the cable, if the cable is longer than 30m (2-wire) or 3m (3- or 4-wire), or if it is
run outside of the building.
Use power supplies which guarantee reliable electrical isolation of the operating
voltage as per IEC/DIN EN 60204-1. Consider also the general requirements for PELV
circuits in accordance with IEC/DIN EN 60204-1.
Ingress protection per IEC 60529 (The ingress protection classes specified only apply
while the pressure sensor is connected with female connectors that provide the
corresponding ingress protection).
Ensure that the cable diameter you select fits to the cable gland of the connector.
Ensure that the cable gland of the mounted connector is positioned correctly and that
the sealings are available and undamaged. Tighten the threaded connection and check
the correct position of the sealings in order to ensure the ingress protection.
Please make sure that the ends of cables with flying leads do not allow any ingress of moisture.
