7. Starting, operation
MSM, Modular Surface Mount (only WU-16)
Please observe the corresponding technical specifications, such as torques and mounting position of the contact compo-
nents.
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, if the cable is longer than 30 m (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
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 undam-
aged. 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.
The transducer must be connected and operated in accordance with the approriate regulations. Take care
to ensure that the electrical connection (e.g. M12 connector) is correctly made (fully sealed).
The WIKA WU Series transducer is designed to operate with an input voltage of DC 10 ... 30 V (DC 14 ... 30 V with output
signal DC 0.1 ... 10.1 V and DC 0 ... 10 V). The interrelationship between voltage supply and load resistor (R
