Electrical connection
Connect the instrument to earth via the pressure connection.

For transmitter with voltage output signal: Operate the pressure transmitter with a

shielded cable and earth the shield at least on one side of the cable, if the cable is
longer than 30 m or if it is run outside of the building.
 For North America: The connection shall be made to „Class 2 Circuits" or „Class 2
Power Units" according to CEC (Canadian Electrical Code) or NEC (National Electrical
Code).
 Ingress protection per IEC 60529 (The ingress protection classes specified only apply
while the pressure transmitter 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.
