7. Starting, operation
Electrical connection
Connect the instrument to earth via the pressure connection.
Operate the pressure transmitter with a shielded cable and earth the shield at least on
one side of the cable.
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 transmitter is connected with female connectors that provide the
corresponding ingress protection).
PIN assignment of connections according to CiA-DR 0-1
