7. Starting, operation

Operate the level probe 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 if it is run outside of the

building.

There mus be no differences in potential between medium/tank and the grounding of

the junction box and the control cabinet when the shield of the cable is applied.

Ingress protection per IEC 60529

Please make sure that the ends of cables with flying leads do not allow any ingress of

moisture.



With a line transformer you realise the mandatory galvanic isolation of the voltage

and current supply between hazardous and non-hazardous areas and ensure the

safety connection data.
